Perceived Social Support (PSS) and Physical Activity (PA) could have an important role in reducing psychological distress in women with problems in the menopausal period. The aim was to analyze the associations between a) Self-Perceived Health (SPH), prevalence of self-reported depression and anxiety, and mental health and its subscales, through the Goldberg General Health Questionnaire (GHQ-12) with b) the Physical Activity Level (PAL) and c) the PSS, through the Duke-UNC-11 functional social support questionnaire in Spanish women with problems in the menopausal period. This document uses data from the Spanish National Health Survey of 2017, focusing on women between 40 and 69 years of age with problems in the menopausal period. Dependency relationships were found between the prevalence of depression and PAL, anxiety and PAL, and SPH with PAL ( p  < 0.001). Weak inverse correlations were found between PAL and mental health, Coping Success, Self-confidence, and Stress (rho: - 0.214 to - 0.258; p  < 0.001). Also, weak and very weak significant inverse correlations were found between PAL and all items of the GHQ-12. Weak inverse correlations were found between PSS scores and mental health, Coping, and Stress (r: -0.201 to - 0.304; p  < 0.001). Likewise, weak and very weak inverse correlations, although statistically significant, were found between the PSS scores and the responses to the GHQ-12 items. Very active women with higher PSS have less psychological distress, higher self-esteem, and better prevalence of positive health.

Subjective cognitive impairment in older persons has a substantial influence on their quality of life and can progress to serious illnesses such as dementia. Physical activity level can help prevent cognitive decline and improve cognitive performance. The aim of this study was to investigate the association between frequency of physical activity and subjective cognitive impairment in Spanish adults aged 65 and over, and to identify different risk factors. Using data from the EHSS20 survey, the study focused on 7082 participants who provided information on cognitive impairment and physical activity. Key predictor variables included age, gender, BMI, marital status, and education level. A significant relationship was found between BMI category and gender, with 66.5% of the population being overweight or obese. Men were more likely to be overweight than women. Socio-demographic factors such as educational level, marital status, and physical activity frequency showed dependent associations with sex. Women had a higher prevalence of subjective cognitive impairment than men. A strong association was found between frequency of physical activity and subjective cognitive impairment, with inactive older people having the highest prevalence of subjective cognitive impairment. Older women who engage in little physical exercise and have less education are at risk for subjective cognitive impairment. Furthermore, for both men and women, being overweight was associated with a more reduced risk than obesity. Significant relationships were also discovered between subjective cognitive impairment, frequency of physical exercise, gender, BMI, and degree of education. In conclusion, older, sedentary women with high BMI and less education are more likely to experience subjective cognitive impairment.

The proportion of aged populations is increasing worldwide. Exercise has a palliating effect on some adverse implications of aging. Multicomponent training (MCT) is a recommended form of exercise for the aged population. The aims of this research were to (1) study the number of publications regarding MCT in the aged population following an exponential growth rate; (2) identify the journals, authors, and countries that stand out the most in this area; and (3) describe the most common themes and used keywords in this field. The analysis was performed through the traditional laws of bibliometrics, including, Price's, Lotka's, Bradford's, and Zipf's law. All documents published in journals indexed in the Web of Science (WoS) Core Collection from 2001 to November 2023 that met the inclusion criteria were included. The 485 documents included in this review revealed that the number of annual publications experienced an exponential growth phase, 15 journals with six or more publications formed the core journals on this topic, and the author Mikel Izquierdo and his collaborative network topped the lists of prominent and prolific co-authors. Spain was the leading country in number of publications. Various thematic lines and keywords regarding strength, sarcopenia, quality of life, falls, balance, dual-task exercise, and cognitive and physical functioning were identified. In conclusion, this work confirmed that research on this topic is going through an exponential growth phase and provided detailed information about the journals, authors, and countries involved in the subject, as well as the keywords most frequently used in the subject matter.

High-intensity activities are related to success in football. We looked at whether high-intensity activity differed between home and away matches and its impact on the final score. Thirty football players (20.3 ± 0.8 years) were recruited from a Spanish semi-professional team. Footballers wore a GPS device to monitor high-intensity parameters from competition matches. The final score of every match was also recorded. Playing at home showed greater total distance (TD) > 24 km/h, >27 km/h, >85% Vmax, and the number of sprints > 24 km/h (all p < 0.05) than playing away. Positive correlations were also found between the match score and high-speed running (HSR) distance covered by the team per minute (r = 0.401), TD > 21 km/h (r = 0.417), TD > 24 km/h (r = 0.343), number of sprints > 24 km/h (r = 0.337), and HSR per minute (r = 0.459) (all p < 0.05). The results suggest that playing at home is associated with greater high-intensity effort than playing away. Moreover, the volume of high-intensity effort influences the final score.

Aims: The present study sought to analyze the effects of 6-month multicomponent training (MCT) combined with a 4-month detraining on metabolic syndrome (MetS) profile among older adults with decreased functional capacity., Methods: This quasi-experimental study included a total of 104 older adults (80.5 ± 6.0 years) and the sample was divided into a training (TRAIN, n = 55) or control group (CON). Harmonized definition was used to diagnose the MetS. Functional capacity, blood biochemical parameters, blood pressure, body composition and anthropometric measurements were assessed 3 times. Analysis of variance for repeated measures and Wilcoxon signed-rank test were used to check the differences within groups., Results: TRAIN decreased diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDLC) and total fat mass during training period, whereas CON did not show any significant changes. During detraining, TRAIN increased HDLC, systolic blood pressure (SBP), waist circumference (WC) and total fat mass; and decreased glucose and fat free mass, whereas CON increased the concentration of glucose and HDLC. From baseline to post-detraining assessment, CON increased the concentration of triglycerides and the WC, while TRAIN only increased the WC (all p < 0.05)., Conclusions: Exercise can be a key component in the treatment of the MetS, since MCT seems to be effective to decrease DBP and total fat mass. Nevertheless, 4-months of detraining could cause a drop of total fat mass, but no in DBP. To avoid reversibility of the benefits obtained, it could be beneficial to promote continuing exercise programs., Trial Registration: ClinicalTrial.gov identifier: NCT03831841., Competing Interests: Declaration of competing interest None., (Copyright © 2024 The Authors.

Over the past few years, organizations around the world have tried to reach different populations with recommendations about physical activity (PA), due to this subject playing an important role in the phases of intention development and in preparation for it. Thus, the knowledge of future educators in the fields of health and PA is of vital importance when improving the levels of the latter in students. The objective of this research is to determine what knowledge future teachers have about health and PA, examining possible disparities according to the gender, age, and level of physical exercise of the participants. In addition, the psychometric properties of the instrument used were explored. A total of 321 Colombian university students from the Faculty of Education between the ages of sixteen and thirty-five participated in this study, providing sociodemographic information by filling out the CUAFYS-A questionnaire. Significant differences were found in the scale items according to sex and self-perception of being physically active. Also, the findings revealed a single-factor structure with nine items that had satisfactory reliability (α = 0.71; CR = 0.72) and excellent goodness-of-fit indices (RMSEA = 0.055 (90% CI (0.3, 0.8), RMSR = 0.02, CFI = 0.935, NNFI = 0.912, CMIN/DF = 1.97). Therefore, strategies and campaigns to promote PA knowledge in prospective teachers should be tailored according to gender and PA levels. Similarly, the CUAFYS-A questionnaire can be considered a valid and reliable instrument to identify the PA knowledge of future educators.

Aging leads to physiological changes affecting body composition, mediated by lifestyle. However, the effectiveness of organized physical activities (OPAs) in attenuating or delaying these age-related transformations remains an area of limited understanding. The primary objectives of this study were threefold: (I) to comprehensively assess the evolution of body composition in a cohort of Spanish older adults over an 8-year period; (II) to compare this evolution in the different age groups; and (III) to investigate the influence of active engagement in OPAs on these age-related changes. From a sample of 3136 Spanish older adults recruited in 2008, 651 agreed to participate in the 8-year follow-up. Anthropometric and bioelectrical impedance data were included for 507 females (70.3 ± 4.4 years) and 144 males (77.8 ± 4.5 years). Age groups were categorized as follows: youngest (65-69 years), mid (70-74 years), and oldest (≥75 years). The engagement in OPA was recorded before and after the follow-up. A repeated measures ANOVA was performed to evaluate the 8-year changes. Males increased in hip (98.1 ± 9.3 vs. 101.5 ± 10.2 cm) and waist circumferences (101.2 ± 6.6 vs. 103.2 ± 6.1 cm), specifically in the youngest group ( p < 0.05). Females decreased in weight (67.6 ± 10.0 vs. 66.6 ± 10.5 kg) and fat mass percentage (39.3 ± 5 vs. 38.8 ± 5.4%) and increased in hip circumference (104.4 ± 9.0 vs. 106.5 ± 9.7 cm); these effects were the most remarkable in the oldest group (all p < 0.05). OPA engagement seemed to slow down fat-free mass loses in males, but not in females (grouped by time, p < 0.05). Body composition changes caused by aging seem to happen earlier in males than in females. Moreover, participating in OPAs does not prevent fat-free mass due to aging.

Background/objective: This study presents the first Report Card from Extremadura (Spain), concerning the 4th edition of Global Matrix (GM), which aimed to provide an assessment of Physical Activity (PA) in children and adolescents based on 10 common indicators defined by GM., Methods: This Report Card was developed by 34 experts from 8 public institutions and 5 research groups from Extremadura and audited by the Active Healthy Kids Global Alliance (AHKGA). All documents, up to July 2021, were analyzed to grade the 10 indicators according to the benchmarks set out by the AHKGA (scale ranging from A to F)., Results: Information was reported in 8 of the 10 indicators, only Active Play and Active Transportation were not reported due to a lack of local information. The other 8 indicators were graded as follows: Overall Physical Activity : F; Organized Sport and Physical Activity : D+, Sedentary Behavior : D, Physical Fitness : C+, Family and Peers : A, School : C+, Community and Environment : B, and Government : C-. In addition, some of the indicators were evaluated according to gender; boys scored higher than girls in Overall Physical Activity (D-vs. F); Organized Sport and Physical Activity (C vs. D) and Physical Fitness (C- vs. D+)., Conclusion: The first Report Card from Extremadura in the GM initiative revealed low compliance with international guidelines on PA and sedentary behavior. Despite high grades for sources of influence, the implemented actions have not been effective yet, and there is no information on Active Play and Active Transportation . These results will allow regional authorities to act at a more local level, as Extremadura's administrative framework allows public administrations and political institutions to act in terms of legislative and budgetary powers among others, which is important for resource allocation., Competing Interests: A conflict of interest occurs when an individual's objectivity is potentially compromised by a desire for financial gain, prominence, professional advancement or a successful outcome. JESF Editors strive to ensure that what is published in the Journal is as balanced, objective and evidence-based as possible. Since it can be difficult to distinguish between an actual conflict of interest and a perceived conflict of interest, the Journal requires authors to disclose all and any potential conflicts of interest., (© 2023 The Society of Chinese Scholars on Exercise Physiology and Fitness.

Achieving a high quality of life in older adults can be difficult if they have limited physical function. The aims of this study were to evaluate the relationship between baseline values and variations in body composition, fitness, and nutritional status on health-related quality of life (HRQoL) and to describe the effects of a 6-month multicomponent training (MCT) programme and a 4-month detraining period on HRQoL. A total of 106 participants with limited physical function were included in this study (age: 80.8 ± 5.9 years; 74 females) and were divided into two groups: control (CON) and intervention (TRAIN). HRQoL was measured using the EQ-5D-3L questionnaire and a visual analogue scale (EQ-VAS). Information on body composition, physical fitness, Mediterranean diet adherence, and nutritional status were obtained. Healthier baseline values for body composition, fitness and nutritional status were associated with better HRQoL (explaining 23.7-55.4%). The TRAIN group showed increased HRQoL during this 6-month MCT, showing group-by-time interaction ( p < 0.05) and a deleterious effect of detraining. Changes in weight, arm strength, and aerobic capacity contributed to explaining 36% of the HRQoL changes obtained with MCT (all p < 0.05). This MCT improved HRQoL in older adults with limited physical function. However, HRQoL returned to baseline values after detraining. This study highlights the importance of performing ongoing programs in this population.

The aims of this study were (1) to analyse the effects of a 6-month multicomponent training (MCT) on the physical fitness of older adults with or at risk of frailty; (2) to study the consequences of a 4-month detraining period; (3) to analyse the influence of frailty status on the training and detraining adaptations. A total of 102 robust, frail and prefrail older adults (80.1 ± 6.1 y) were divided into an intervention (TRAIN) and control group (CON). The TRAIN performed a 6-month MCT, while the CON continued with their usual lifestyle. Fitness assessment was mainly based on the Senior Fitness Test. Four evaluations were carried out; at baseline, and at 3, 6 and 10 months from baseline. Linear mixed models were performed to analyse group by time interactions and to compare differences in changes within groups between different time points. After 6-month MCT, TRAIN showed greater improvements for all fitness variables (group effects p  < 0.05, except for flexibility) when compared to the CON. During the 4-month detraining period, TRAIN significantly decreased their balance, upper-limb flexibility and upper and lower-limb strength (all p  < 0.05). CON only decreased upper-limb flexibility. When accounting for frailty status in the TRAIN, the frail-prefrail showed lower adaptations to the training and were more affected by detraining than the robust. The presented MCT is a good strategy to improve fitness in this population, but its positive effects are limited in time. It is, therefore, critical to avoid detraining periods. Trial registration: ClinicalTrials.gov identifier: NCT03831841. Highlights Our 6-month MCT-program improves the physical fitness of robust, frail and prefrail older adultsA detraining period of four months partially deteriorates the physical fitness of robust, frail and prefrail older adults, so it is recommended to promote ongoing exercise programs or smaller break periodsIt seems that those older adults with a more advanced frailty status may not benefit from exercise to the same degree and will be more affected by detraining. Therefore, trainers may need to individualize training protocols to obtain the greatest exercise benefits.

Physical exercise effects and ageing on fitness may be influenced by nutritional status. This study investigates the effects of a 6-month multicomponent exercise training (MCT) on nutritional status and evaluates if this type of exercise could affect differently body composition and physical fitness depending on the nutritional status of older adults with decreased functional capacity. Ninety-three participants (80.4 ± 6.0 y) were divided into control ( n  = 45) and intervention ( n  = 48) groups. The intervention consisted of a 6-month multicomponent training. Comparisons between changes in body composition and fitness during the 6-months were performed between individuals at risk of malnutrition and those well-nourished, according to the Mini Nutritional Assessment. Model mixed-effect analyses were used to investigate differences after the 6 months of MCT between groups. Well-nourished participants compared with those at risk of malnutrition had higher: arm (13.4 ± 3.5 vs 14.3 ± 33.6 repetitions) and leg strength (9.0 ± 3.0 vs 11.1 ± 3.3 repetitions), maximum walking speed (31.6 ± 13.1 vs 23.7 ± 6.3s), agility (11.9 ± 5.8 vs 8.3 ± 2.1s), and aerobic capacity (31.6 ± 13.1 vs 23.7 ± 6.3 m), at baseline. After the training, those without risk of malnutrition in CON decreased their nutritional status (-1.7 + 0.7 points). Those well-nourished that performed the intervention decreased total fat mass (-1.0 ± 0.3 kg) and body fat percentage (-1.2 ± 0.4%). Both groups of training improved similarly in all tests, except for balance, in which the well-nourished showed improvements of 6.3 ± 1.9s. These results underline the usefulness of MCT in improving physical fitness regardless of nutritional status and preventing nutritional status detriment in well-nourished older adults, who are fitter and benefit more, in terms of body composition. Trial registration: ClinicalTrials.gov identifier: NCT03831841. Highlights Multicomponent exercise programme seems to be effective in delaying detriments in the nutritional status of well-nourished people.Well-nourished older people obtain more benefits in body composition from the multicomponent exercise than those at risk of malnutrition, decreasing adiposity.The positive effect of multicomponent exercise was observed in physical fitness independently of nutritional status.

Adolescence is a stage of crucial physiological and psychological changes within the individual's life cycle, where fitness work is important. With self-perception being crucial in relation to adolescent health and well-being, a positive perception of fitness is directly related to increased practice or higher level of physical activity (PA). Thus, the aims were: (1) to analyze, with the Visual Analogue Fitness Perception Scale for Adolescents (FP VAS A), the self-perceived physical fitness (PF) of high school students, (2) to investigate if there are differences according to sex and school location, and (3) to study the correlations between the items of the FP VAS A with age and body mass index (BMI). For this purpose, a cross-sectional study was designed with a total of 961 participants, 48.8% boys and 51.2% girls in secondary education, where 31.9% studied in rural schools and 68.1% in urban schools. The FP VAS A scale was used to assess self-reported PF. Regarding the results, there were statistically significant differences between sexes ( p < 0.001), with boys showing higher scores than girls in all the items of the FP VAS A scale, with the exception of global flexibility. Inverse, mean and significant correlations were established between BMI and self-perceived overall PF (r = -0.202; p < 0.001), cardiorespiratory endurance (r = -0.226; p < 0.001) and movement speed (r = -0.268; p < 0.001). Between age and self-perceived cardiorespiratory endurance (r = -0.138; p < 0.001) an inverse, mean and significant correlation was also observed. In conclusion, boys showed a better self-perception of PF than girls for all physical abilities, with the exception of flexibility. School location was not shown to influence students' self-perceived PF. In addition, most of the self-perceived PF abilities for overall fitness correlated inversely with BMI.

Background: This systematic review and meta-analysis set out to determine the efficacy of whole-body muscle electrostimulation on body composition, strength, and muscle power in active and non-active adults (aged ≥18 years)., Method: This review was reported in accordance with the Protocol Statement of Preferred Reporting Element Guidelines for Systematic Reviews and Meta-Analysis included controlled trials; whole-body electromyostimulation trials with at least 1 exercise and control group; participants >18 years old. Outcome measures were defined as standardized mean differences for muscle mass, body fat mass, strength, and power. Studies were searched in the following electronic databases: PubMed, Web of Science, Scopus, SPORTDiscus, and EMBASE for all articles published up to July 30, 2021. The risk of bias was assessed by 2 independent researchers using the Physiotherapy Evidence Database scale and Grading of Recommendations, Assessment, Development and Evaluations approach. Analyses were performed using the metafor package of the statistical software R (version 4.0.3; R Core Team, 2020). Random effects models, forest, and funnel plots to quantify the asymmetry associated with publication bias were fitted using the metafor library in R. Statistical heterogeneity was assessed using I2 statistics., Results: In total, 26 studies representing 1183 participants were included (WB-electromyostimulation: n = 586 and control group: n = 597). The mean age of the participants ranged from a minimum of 20.4 to a maximum of 77.4 years old. Interventions lasted a minimum of 4 and a maximum of 54 weeks. Standardized mean difference was 0.36 (95% confidence interval [CI]: 0.16-0.57) for muscle mass, -0.38 (95% CI: -0.62-0.15) for body fat, 0.54 (95% CI: 0.35-0.72) for strength, and 0.36 (95% CI: 0.02-0.71) for power with significant differences between groups (all P < .04). I2 revealed low heterogeneity of muscle mass (15%) and power (0%) between trials and medium heterogeneity of body fat (45%) and strength (55%)., Conclusion: We concluded that WB-electromyostimulation has significant positive effects on muscle mass, body fat, strength, and power., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Inclusive education is a right that has captured the attention of public institutions, researchers, and teaching professionals around the world. The beliefs and perceptions of teachers are a fundamental axis in knowing the state of these professionals regarding this ethical principle, allowing them to develop and implement different strategies. This study aims to explore the reliability and factor structure of the Evaluation of Teachers' Preparation for Inclusion (CEFI-R) questionnaire among physical education teachers. The sample consisted of 789 Spanish in-service teachers who completed the questionnaire to assess their readiness for inclusion in this subject. Exploratory and confirmatory factor analyses as well as reliability testing were carried out. A factor structure with four dimensions (conception of diversity, methodology, support, and community participation) was obtained. These dimensions consisted of 17 items with good and excellent goodness-of-fit values. In addition, a high reliability was obtained (Cronbach's Alpha = 0.71-0.93). Therefore, the CEFI-R could be considered a valid and reliable tool to analyze physical education teachers' perceptions of their preparedness for inclusive education.

People with Alzheimer's disease (AD) diagnosis who get informal care remain at home longer, reducing the demand for healthcare resources but increasing the stress of caregiving. Research on the effectiveness of physical training, psychoeducational, cognitive-behavioural, and health education programs in reducing the caregiver load and enhancing health-related quality of life (HRQoL) exist, but none exist about an integrated interdisciplinary program. The goals of this project are (1) to assess the Integral-CARE Interdisciplinary Program (IP) applicability, safety, effects on HRQoL, and the incremental cost-effectiveness ratio for AD caregivers; (2) to evaluate the IP applicability and cost-effectiveness to enhance the physical, psychoemotional, cognitive-behavioural dimensions, and the health education status of informal caregivers, and (3) to study the transference of the results to the public and private sectors. A randomized controlled trial will be conducted with an experimental (IP) and a control group (no intervention). The PI will be conducted over nine months using face-to-face sessions (twice a week) and virtual sessions on an online platform (once a week). There will be an initial, interim (every three months), and final assessment. Focus groups with social and health agents will be organized to determine the most important information to convey to the public and private sectors in Extremadura (Spain). Applicability, safety, HRQoL, incremental cost-effectiveness ratio, and HRQoL will be the main outcome measures, while secondary measures will include sociodemographic data; physical, psychoemotional, health education, and cognitive-behavioural domains; program adherence; and patient health status. Data will be examined per procedure and intention to treat. A cost-effectiveness study will also be performed from the viewpoints of private and public healthcare resources.

Background: The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children's and adolescents' (5-17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to the Human Development Index and geo-cultural regions., Methods: A total of 57 Report Card teams followed a harmonized process to grade the 10 common PA indicators. An online survey was conducted to collect Report Card Leaders' top 3 priorities for each PA indicator and their opinions on how the COVID-19 pandemic impacted child and adolescent PA indicators in their country., Results: Overall Physical Activity was the indicator with the lowest global average grade (D), while School and Community and Environment were the indicators with the highest global average grade (C+). An overview of the global situation in terms of surveillance and prevalence is provided for all 10 common PA indicators, followed by priorities and examples to support the development of strategies and policies internationally., Conclusions: The Global Matrix 4.0 represents the largest compilation of children's and adolescents' PA indicators to date. While variation in data sources informing the grades across countries was observed, this initiative highlighted low PA levels in children and adolescents globally. Measures to contain the COVID-19 pandemic, local/international conflicts, climate change, and economic change threaten to worsen this situation.

This study aimed: To analyze the effects of 6-month multicomponent training (MCT) and 4-month detraining on functional capacity and frailty among older adults with/at risk of frailty and to analyze the influence of frailty status on training and detraining adaptations. A total of 106 older adults (80.5 ± 6.0 years) were divided into a control (CON) or training group (TRAIN). The TRAIN performed a 6-month MCT (Eelder-fit), while CON continued their usual lifestyle. Functional capacity was assessed by the Short Physical Performance Battery (SPPB), while frailty was evaluated through Fried (FP) and the short version of the Frailty Trait Scale (FTS-5). Linear mixed models were performed to analyze group effects and to compare differences in changes within and between groups. TRAIN showed improvements in SPPB (3.2 ± 2.4), FP (-0.7 ± 1.3), and FTS-5 (-5.9 ± 5.8), whereas CON improved in SPPB (0.7 ± 2.9) and deteriorated in FTS-5 (2.8 ± 7.6) (all p < 0.05). Group effects favorable to TRAIN were found for all scales during this period (all p < 0.05). After detraining, TRAIN worsened in SPPB (-1.2 ± 2.7) and FTS-5 (4.1 ± 6.1) (both p < 0.05). No relevant differences were observed, accounting for frailty status between TRAIN subgroups. Eelder-fit improved the functional capacity and frailty of this population, whereas 4-months of detraining caused a drop of these variables except in FP.

Objective: To determine the link between physical fitness and body composition with nocturnal and nap time in Spanish older adults. Methods: Eight hundred thirty older adults underwent several tests. Sleep was measured using Jenkins Sleep Scale. Nocturnal sleep was categorized (<7, 7-9, and >9 hours), and nap time (no nap, 1-30 minutes, and >30 minutes).Physical fitness was evaluated using validated tests, and body composition by electric bioimpedance. Results: 75.1% of participants were female, mean age 77.7 ± 5.1 years. Mean nocturnal sleep and nap time was 6.7 hours and 23.3 minutes, respectively. Models showed nocturnal sleep >9 hours was significant and positively associated with body shape index (Odds ratio[ OR ] = 4.07 ( p  = .011)) and waist circumference OR  = 1.04 ( p  = .024) in females. Males' waist and hip circumference were positively significantly related to nap time between 1 and 30 minutes, OR  = 1.08, p  = .009 and OR  = 1.08, p  = .048, respectively. In females, nap time >30 minutes was associated with greater fat mass and body shape index OR  = 1.22, p  = .032 and OR  = 3.95, p  = .027, respectively. Physical fitness showed no associations with sleep outcomes. Conclusions: Sleep patterns do not influence physical fitness but body composition, being more related to female body composition as nocturnal and nap sleep were associated with higher fat mass, waist circumference and body shape index, while only short nap times were related to higher waist and hip circumference in males., Competing Interests: Declaration of Conflicting Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2022.)

Introduction: Regular exercise training reduces arterial blood pressure, but the underlying mechanisms are unclear. Here, we evaluated the potential involvement of pannexin 1, an ATP releasing channel, in the blood pressure-reducing effect of training., Methods: Middle-age men, 13 normotensive and 14 nonmedicated stage 1 hypertensive, completed 8 wk of intensive aerobic cycle training. Before and after training, blood pressure and changes in leg vascular conductance, induced by femoral arterial infusion of tyramine (induces endogenous noradrenaline release), acetylcholine, or sodium nitroprusside, were measured during control conditions and after acute pannexin 1 inhibition by probenecid. A skeletal muscle biopsy was obtained from the thigh, pre- and posttraining., Results: Exercise training reduced mean systolic and diastolic blood pressure by ~5 ( P = 0.013) and 5 mm Hg ( P < 0.001), respectively, in the hypertensive group only. The reduction in blood pressure was not related to changes in pannexin 1 function because mean arterial blood pressure and tyramine-induced vasoconstriction remain unaltered by pannexin 1 inhibition after training in both groups. After training, pannexin 1 inhibition enhanced leg vascular conductance in the normo- and hypertensive groups at baseline (41.5%, P = 0.0036, and 37.7%, P = 0.024, respectively) and in response to sodium nitroprusside infusion (275%, P = 0.038, and 188%, P = 0.038, respectively). Training did not alter the pannexin 1 protein expression in skeletal muscle. Training enhanced the vasodilator response to acetylcholine infusion and increased the expression of microvascular function-relevant proteins., Conclusions: The exercise training-induced lowering of arterial blood pressure in nonmedicated hypertensive men does not involve an altered function of pannexin 1., (Copyright © 2022 by the American College of Sports Medicine.)

Introduction: depression and anxiety is one of the most relevant public health problems. The link between smoking and depression has been demonstrated. Regular physical activity (PA) could act as a protector against mental health diseases. Objectives: (1) to explore the prevalence of depression and anxiety in relation to sex and to the condition of smoker and ex-smoker, (2) to study the differences in prevalence proportions according to the frequency and level of PA, and (3) to calculate the probability of presenting depression or anxiety according to the frequency and level of PA. Methods: a cross-sectional study was conducted, based on data extracted from the 2014 and 2020 Spanish European Health Survey and the 2017 Spanish National Health Survey. The sample included 9524, 7813, and 9079 participants, respectively. Descriptive analysis was performed (comparisons using a Chi-square test and z-test for independent proportions). Probability odds ratios of anxiety and depression were calculated according to PA. Results: women had a higher prevalence of depression and anxiety than men (p < 0.001−0.003). Higher levels of prevalence were observed in inactive people versus very active or active people (p < 0.001). Inactive people had a higher risk of depression and anxiety compared to very active people. Conclusion: inactive smokers and ex-smokers had higher levels of prevalence of depression and anxiety than active and very active people. Physical inactivity could increase the risk of suffering these mental disorders in this population. This could affect women more than men.

Introduction: Reducing the prevalence of hypertension is a major priority of the World Health Organization (WHO). Its high prevalence and associated risks generate high economic and social costs. Physical activity (PA) is associated with a decrease in hypertension and in the use of antihypertensive drugs., Objective: To explore the association between PA levels (PAL), prevalence of hypertension and the use of antihypertensive drugs in Spanish population. To calculate risks of hypertension and use of antihypertensive in the inactive versus physically active population., Method: This cross-sectional study used data from 17717 individuals, sampled in the 2017 National Health Survey. Interaction by sex, age groups, body mass index (BMI), hypertension prevalence, antihypertensive drugs use and PAL, using a pairwise z-test, and dependence relationships between variables, were studied using a chi square test. Odds ratios of hypertension and antihypertensive drug use were calculated among the inactive and the physically active populations., Results: The findings showed a significant inverse association between prevalence of hypertension, antihypertensive use, and PAL in both sexes and different age and BMI groups, with lower prevalence of hypertension and antihypertensive use when PAL were higher. The risks of hypertension and antihypertensive use seems to be reduced when related to higher PAL compared to inactive people., Conclusions: High PAL is associated with lower prevalence of hypertension and lower antihypertensive use. Thus, being physically active or very active may reduce the risks of suffering from hypertension and the need to use antihypertensives compared to inactive people or walkers.

Purpose: To investigate differences in athletes' knowledge, beliefs, and training practices during COVID-19 lockdowns with reference to sport classification and sex. This work extends an initial descriptive evaluation focusing on athlete classification., Methods: Athletes (12,526; 66% male; 142 countries) completed an online survey (May-July 2020) assessing knowledge, beliefs, and practices toward training. Sports were classified as team sports (45%), endurance (20%), power/technical (10%), combat (9%), aquatic (6%), recreational (4%), racquet (3%), precision (2%), parasports (1%), and others (1%). Further analysis by sex was performed., Results: During lockdown, athletes practiced body-weight-based exercises routinely (67% females and 64% males), ranging from 50% (precision) to 78% (parasports). More sport-specific technical skills were performed in combat, parasports, and precision (∼50%) than other sports (∼35%). Most athletes (range: 50% [parasports] to 75% [endurance]) performed cardiorespiratory training (trivial sex differences). Compared to prelockdown, perceived training intensity was reduced by 29% to 41%, depending on sport (largest decline: ∼38% in team sports, unaffected by sex). Some athletes (range: 7%-49%) maintained their training intensity for strength, endurance, speed, plyometric, change-of-direction, and technical training. Athletes who previously trained ≥5 sessions per week reduced their volume (range: 18%-28%) during lockdown. The proportion of athletes (81%) training ≥60 min/session reduced by 31% to 43% during lockdown. Males and females had comparable moderate levels of training knowledge (56% vs 58%) and beliefs/attitudes (54% vs 56%)., Conclusions: Changes in athletes' training practices were sport-specific, with few or no sex differences. Team-based sports were generally more susceptible to changes than individual sports. Policy makers should provide athletes with specific training arrangements and educational resources to facilitate remote and/or home-based training during lockdown-type events.

Metabolic syndrome (MetS) is a cluster of medical conditions associated with several health disorders. MetS and frailty can be related to prolonged physical deconditioning. There is a need to know whether there is concordance between the different ways of diagnosing it and to know their prevalence in Spanish older adults. Thus, the aims of this study were to describe the prevalence of MetS; to analyse the concordance between different definitions to diagnose MetS; and to study the associations between MetS, frailty status, and physical activity (PA) in older adults with decreased functional capacity. This report is a cross-sectional study involving 110 Spanish older adults of ages ≥65 years with decreased functional capacity. Clinical criteria to diagnose MetS was defined by different expert groups. Anthropometric measurements, blood biochemical analysis, frailty status, functional capacity, and PA were assessed. The Kappa statistic was used to determine the agreement between the five MetS definitions used. Student's t -test and the Pearson chi-square test were used to examine differences between sex, frailty, and PA groups. The sex-adjusted prevalence of MetS assessed by the National Cholesterol Education Program-Third Adult Treatment Panel was 39.4% in men and 32.5% in women. The International Diabetes Federation and the Harmonized definitions had the best agreement (k = 1.000). The highest odds ratios (ORs) of cardiometabolic risk factors to develop MetS were elevated triglycerides (37.5) and reduced high-density lipoprotein cholesterol (27.3). Central obesity and hypertension prevalence were significantly higher in the non-active group (70.7% and 26.8%, respectively), compared to the active group (50.0% and 7.7%, respectively). Moreover, the active group (OR = 0.85, 95% CI = 0.35, 2.04) and active women group (OR = 0.77, 95% CI = 0.27, 2.20) appeared to show a lower risk of developing this syndrome. MetS is highly prevalent in this sample and changes according to the definition used. It seems that sex and frailty do not influence the development of MetS. However, PA appears to decrease central obesity, hypertension, and the risk of developing MetS.

Background: Increased physical activity (PA) is a very important factor in a healthy aging lifestyle. Psychosocial factors have also a main role in the initiation and maintenance of this behavior, but nowadays its implications for frailty elderly people are unknown, therefore, the aim of this study was to identify the psychosociological variables of behavior change that influence the practice of (PA) in frail and prefrail elderly., Methods: A total of 103 frail and pre-frail elderly people (72 females) participated in this cross-sectional study, on the framework of the EXERNET-Elder3.0 project. Age ranged from 68-94 years (mean = 80.4 ± 5.9 years). Individualized face-to-face interviews according to the constructs of the Transtheoretical Model of Change (TTM) [(decisional balance (DB) and self-efficacy (SE)], social support (SS) (family and friends) and outcome expectations (OE) were administered to all participants., Results: Significant differences were found in DB, perceived benefits (PBn), SE, family-related SS and OE as a function of stages of change (SoC) (p < 0.005), but no significant were found in perceived barriers (PBrr) (p = 0.259) and friends-related SS (p = 0.068). According to the Scheffé post-hoc test, those in advanced SoC (Action-Maintenance), scored higher than those in lower SoC (Precontemplation-Contemplation and Preparation)., Conclusion: The scores obtained from the study variables differed according to the SoC, supporting the external validity for the use of the TTM in frailty elderly. Further research is needed to determine the impact of PBrr and friends-related SS on this people, as well as to identify the validity of this model in the long-term in this population., (© 2022.

Background: Physical fitness and body composition are important health indicators; nevertheless, their combined pattern interrelationships and their association with mortality are poorly investigated., Methods: This longitudinal study is part of the Spanish EXERNET-Elder project. Person-months of follow-up were calculated from the interview date, performed between June 2008 and November 2009, until the date of death or censoring on March 2018 (whichever came first). In order to be included, participants had to fulfill the following criteria: (a) be older than 65 years, (b) live independently at home, (c) not suffer dementia and/or cancer, and (d) have a body mass index above 18.5. Body fat and weight were assessed by a bioelectrical impedance analyzer. Fitness was measured with the Senior Fitness and the one-leg static balance tests. The Spanish Death Index was consulted for the death's identification. Cluster analysis was performed to identify Fat-Fit patterns and traditional cut-points and percentiles to create the Fat-Fit groups. Cox proportional hazards regression models were used to calculate the hazard ratios (HRs) of death in clustered Fat-Fit patterns and in traditional Fat-Fit groups., Results: A total of 2299 older adults (76.8% of women) were included with a baseline mean age of 71.9 ± 5.2 years. A total of 196 deaths (8.7% of the sample) were identified during the 8 years of follow-up. Four clustered Fat-Fit patterns (Low fat-Fit, Medium fat-Fit, High fat-Unfit, and Low fat-Unfit) and 9 traditional Fat-Fit groups emerged. Using the Low fat-Fit pattern as the reference, significantly increased mortality was noted in High fat-Unfit (HR: 1.68, CI: 1.06-2.66) and Low fat-Unfit (HR: 2.01, CI: 1.28-3.16) groups. All the traditional Fit groups showed lower mortality risk when compared to the reference group (obese-unfit group)., Conclusion: Physical fitness is a determinant factor in terms of survival in community-dwelling older adults, independently of adiposity levels., (© The Author(s) 2021.

Introduction: The multiple benefits of physical activity (PA) compared to the current lack of adherence to this behavior in older people makes it necessary to identify the factors related to its long-term dropout, therefore, the aim of this study was: (i) to study the evolution of behavior change for PA through stages of change (SoC) after 8 years and, to identify the associated factors related to the worsening of SoC for PA., Methods: A total of 714 Spanish older adults (>65 years) participated in the Longitudinal elderly EXERNET study 8 years follow-up. SoC for PA from Transtheoretical model of behavior change (TTM), body composition [BMI, fat mass, lean mass, waist circumference (WC), and hip circumference (HC)] and physical fitness (EXERNET battery fitness tests) were recorded. A multivariate binary logistic regression model was used to identify the potential predictive factors of worsening SoC for PA., Results: Three hundred and sixty participants (50.4%) worsening their SoC for PA after 8 years. Predictors factors associated with worsening of SoC were: HC (OR = 1.022; 95% CI: 1.001, 1.044), Lower body strength (OR = 0.940; 95% CI: 0.887, 0.997) and aerobic endurance at the 6 min-walk test (OR = 0.997; 95% CI: 0.995, 0.999)., Conclusion: This study highlights that we need to identify adults with high HC, lower body strength and lower aerobic endurance to design a tailored PA program. Identifying the determinants of losing adherence to PA will help in the creation, design, and evaluation of exercise programs with the goal of reducing older adults' drop-outs rates., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Jiménez-Zazo, Hernández-Martínez, Romero-Blanco, Cabanillas, Pérez-Gómez, Ara, Casajús, Vicente-Rodríguez, Gesteiro, González-Gross and Aznar.)

Background: The second-to-fourth digit ratio (2D:4D) has been calculated for individual athletes and sports, but it has not been investigated in futsal performance. Therefore, the aim of this study was to investigate any relationships between 2D:4D of the dominant and non-dominant hands and physical capacity performances, selected functional variables and hormone concentrations in elite female futsal players., Methods: Twenty-four elite female futsal players were measured for 2D:4D in the dominant (2D:4D D ) and non-dominant (2D:4D ND ) hand. The futsal specific performance test (FSPT), hand-grip strength (HGS) and aerobic power were also assessed. In addition, selected circulatory hormones were measured (estradiol, cortisol, growth hormone and insulin like growth factor-1). Pearson's correlation test was used to identify correlational relationships., Results: Total test-time and performance time (total time + penalty time) for the FSPT showed a significant correlation with 2D:4D D (r = 0.53, p = 0.005 and r = 0.55, p = 0.003, respectively). HGS ND also displayed a significant correlation with the 2D:4D D (r = 0.59, p = 0.002). Aerobic power and time spent running on the treadmill also showed a significant relationship with 2D:4D ND (both, r = 0.54, p = 0.006). Cortisol showed a significant correlation with 2D:4D D (- 0.58, p = 0.003) and 2D:4D ND (- 0.52, p = 0.008)., Conclusions: The measurement of 2D:4D ratio could be an important factor in determining potential performance attributes and talent identification of elite female futsal players. Further studies are needed in this area to further examine the results presented here., (© 2022. The Author(s).)

Purpose: To assess and compare the HRQoL and physical fitness of polio survivors with healthy individuals., Methods: Thirty-seven polio survivors and 40 healthy individuals were recruited in this cross-sectional study. The Fatigue Severity Scale (FSS) was used to evaluate participant's level of fatigue; Short Form 36 (SF-36) was used for evaluating HRQoL, and hand-grip strength, lumbar trunk muscle endurance, flexibility, balance, and aerobic endurance were used as measures for physical fitness., Results: Polio survivors had lower HRQoL in most of the dimensions of the SF-36, and they showed a lower level of physical fitness than controls. In particular, mobility-related variables were 20-40% lower in people with PP., Conclusions: Subjects with PP had lower scores for the physical component of the HRQoL questionnaire, reduced physical fitness, increased fatigue, less mobility, and a higher fall risk than controls. The outcomes of the study can be useful to the design of future programs tailored specifically to improve the assessment of the physical fitness of subjects with paralytic polio and to facilitate interventions based on appropriate physical exercise regimens.Implications for rehabilitationPost-polio syndrome is a disabling disease that impacts in fitness, physical and psychological health-related quality of life of polio survivors.Polio survivors should undergo physical activity programs that focus on improving mainly their mobility and physical functioning (walking, self-care, and climbing stairs), thereby reducing fall risk and fatigue.Individual tailored physical exercise programs should be promoted in order to improve HRQoL in this population.

Objective: Our objective was to explore the training-related knowledge, beliefs, and practices of athletes and the influence of lockdowns in response to the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)., Methods: Athletes (n = 12,526, comprising 13% world class, 21% international, 36% national, 24% state, and 6% recreational) completed an online survey that was available from 17 May to 5 July 2020 and explored their training behaviors (training knowledge, beliefs/attitudes, and practices), including specific questions on their training intensity, frequency, and session duration before and during lockdown (March-June 2020)., Results: Overall, 85% of athletes wanted to "maintain training," and 79% disagreed with the statement that it is "okay to not train during lockdown," with a greater prevalence for both in higher-level athletes. In total, 60% of athletes considered "coaching by correspondence (remote coaching)" to be sufficient (highest amongst world-class athletes). During lockdown, < 40% were able to maintain sport-specific training (e.g., long endurance [39%], interval training [35%], weightlifting [33%], plyometric exercise [30%]) at pre-lockdown levels (higher among world-class, international, and national athletes), with most (83%) training for "general fitness and health maintenance" during lockdown. Athletes trained alone (80%) and focused on bodyweight (65%) and cardiovascular (59%) exercise/training during lockdown. Compared with before lockdown, most athletes reported reduced training frequency (from between five and seven sessions per week to four or fewer), shorter training sessions (from ≥ 60 to < 60 min), and lower sport-specific intensity (~ 38% reduction), irrespective of athlete classification., Conclusions: COVID-19-related lockdowns saw marked reductions in athletic training specificity, intensity, frequency, and duration, with notable within-sample differences (by athlete classification). Higher classification athletes had the strongest desire to "maintain" training and the greatest opposition to "not training" during lockdowns. These higher classification athletes retained training specificity to a greater degree than others, probably because of preferential access to limited training resources. More higher classification athletes considered "coaching by correspondence" as sufficient than did lower classification athletes. These lockdown-mediated changes in training were not conducive to maintenance or progression of athletes' physical capacities and were also likely detrimental to athletes' mental health. These data can be used by policy makers, athletes, and their multidisciplinary teams to modulate their practice, with a degree of individualization, in the current and continued pandemic-related scenario. Furthermore, the data may drive training-related educational resources for athletes and their multidisciplinary teams. Such upskilling would provide athletes with evidence to inform their training modifications in response to germane situations (e.g., COVID related, injury, and illness)., (© 2021. The Author(s).)

Background: The present study aimed to quantify training and match load in elite young soccer players over the course of an entire season., Methods: Using a longitudinal design, session-rate of perceived exertion (s-RPE) and its metrics (weekly acute workload [wAW], acute to chronic workload ratio [wACWR], training monotony and training strain) were examined in twenty-one elite young soccer players (mean±standard deviation; age: 16.1±0.2 years; height: 176.8±5.6 cm; body mass: 67.3±5.7 kg; BMI: 21.5±1.4 kg/m 2 ; V̇O2max: 47.6±3.8 mL.kg -1 .min -1 ) during the whole season containing 4 meso-cycles: preseason (Pre-S), early-season (Ear-S), mid-season (Mid-S), and end-season (End-S)., Results: Repeated-measures analysis of variance examined variations in s-RPE load data across the 4 meso-cycles and 1-week of microcycle. Analyzing data revealed the End-S had a significant greater wAW compared to Early-S (P=0.002, g=0.96) and Mid-S (P<0.001, g=1.09). However, no differences between in-season periods were observed in wACWR (P=0.524). The within-week variations revealed significant lower wAW in prematch a day (M D-1 ) (P<0.001), 1 day after match (M D+1 ) (P<0.001) and 2 days after match (M D+2 ) (P<0.001) compared to match day (M D ) for overall team analysis. Additionally, analyses by playing position showed that fullbacks have a significant lower AW in M D+2 compared to M D (P<0.029)., Conclusions: The periodization of training load indicated variations across the whole season in young elite players. The weekly microcycle perceived load could be identified as follows; there are higher training loads on M D-3 and M D-2 which was similar to intensities experienced by players throughout the match play and, furthermore, lower overall WL on the M D+1 and M D+2 in order to ensure the optimal recovery of the players.

Given the importance of sport at a global level, the competitiveness of sport systems is a determining factor in attracting resources from different sectors. Competitiveness is largely measured by the athletes' level. Therefore, the production of competitive talent is an aspect that occupies the managers of different sports systems. This study analyzed the factor structure and reliability of a questionnaire for the evaluation of the perceptions of actors of a sport (canoeing) on the ability of the national system to produce talent in one of its modalities recently incorporated in the Olympic Games (OG) of Tokyo 2021. The sample consisted of 167 individuals linked to Spanish canoeing, who responded to the questionnaire "Evaluation of the current position in canoeing-sport with regard to talent" of the International Canoe Federation (ICF). Exploratory, confirmatory and reliability factor analyses were performed. The results showed a one-dimensional factor structure composed of seven items, with good and excellent goodness-of-fit values and high reliability (McDonald's Omega = 0.82). Thus, the ICF questionnaire can be considered a quick and easy to apply tool to analyze the perceptions about the development of talent in canoeing in order to take actions for the recruitment, promotion and development of talent.

Introduction: Depression is currently the most prevalent mental illness in the world. It is a very frequent geriatric syndrome that causes a high degree of disability and increases mortality in the elderly population. This mental disorder is a social and public health problem that alters the quality of life (Qol) of the patient. Physical strength work has been reported to improve the clinical picture of people with depression., Objective: To determine the relationship between lower body strength, health-related quality of life (HRQoL), depression status and body mass index (BMI) in older women with depression., Design: A cross-sectional descriptive study with 685 elder women with depression., Results: A mild direct correlation (Rho = -0.29; p ≤ 0.001) between stand-ip test and EQ-5D-3L test was shown. There is a mild inverse correlation between stand-up test and six of fifteen items of the Geriatric Depression Scale (GDS) (Rho item 1 = -0.24; p ≤ 0.001; item 4 = 0.11; p ≤ 0.001; item 5 = -0.20; p ≤ 0.001; item 7 = -0.15; p ≤ 0.001; item 11 = -0.19; p ≤ 0.001; item 13 = -0.21; p ≤ 0.001). Between Stand-Up test and BMI, the correlation is weak inverse (Rho = -0.20; p ≤ 0.001)., Conclusions: There is a significant association of lower body strength with HRQoL, and BMI, as well as some variables of depression status in elder women with depression. Better scores in the stand-up test lead to an improvement in HRQoL and BMI. Therefore, stand-up test could be a complementary tool in public health for improve HRQoL in the elderly women with depression.

Background: Age-related changes negatively affect physical fitness, body composition, and executive function and produce a decrease in regucalcin level expression in blood. The square-stepping exercise (SSE) is a balance and lower-limb strength training programme used to prevent falls and stimulate cognitive function in older adults. This project aims to analyse the effects of SSE on executive function, regucalcin expression, fall prevention, body composition, and physical fitness in people over 65 years old., Methods: A randomized controlled trial will be conducted. A total of 90 older people over 65 years old will be recruited and randomly assigned to 2 groups: experimental ( n = 45) and control ( n = 45). The experimental group will perform an SSE-based intervention for 6 months (2 times per week), while the control group do not follow any treatment., Results: The main outcome will be balance, but other motor (body mass index, upper- and lower-limb strength, flexibility, and speed-agility) and cognitive variables (executive functions and attention) will be assessed. The expression of regucalcin levels will also be evaluated. Therefore, this project aims to analyse the effect of a 6-month SSE intervention on cognitive and motor competence, physical fitness, regucalcin levels, fall risk, and body composition in older people. If the intervention proves to be effective, it could be implemented in centres, entities, and associations specialized in elderly care.

Introduction: Depression is a disabling mental illness and therefore also a serious public health problem. It affects 5% of the adult population in the world and is the leading cause of disability, with an annual cost of USD one trillion. In Spain, its prevalence is 13.4%, costing EUR 6000 million a year. Physical inactivity has been linked to an increase in depressive symptoms, with physical activity associated with an improvement in health-related quality of life. Objective: To calculate the odds ratio (OR) and relative risk (RR) of suffering from depression and taking antidepressants in the inactive Spanish population compared to groups with a higher level of physical activity. Method: 17,141 individuals aged 18−69 years residing in Spain and interviewed in the 2017 Spanish National Health Survey were included in this cross-sectional investigation. Results: Dependence relationships were found between the level of physical activity and the prevalence of depression and taking antidepressants (p < 0.001). We found elevated ORs and RRs for depression and antidepressant use in inactive people compared to those with a high/very high level of physical activity (Depression: OR: 4.32. CI95%: 3.35−5.57. RR: 1.59. 95% CI: 1.51−1.68; Antidepressants: OR: 4.95. CI95%: 3.59−6.82. RR: 1.61. CI95%: 1.52−1.71). Conclusions: Belonging to an inactive population group increases the risk of suffering from depression and of taking antidepressants.

Background: Wrestling is considered one of the oldest sports in the world. There is a high rate of injuries in Wrestling. To prevent injuries, it is necessary to identify the risk factors. Despite the functional importance of strength in wrestling, few studies have investigated the relationship between isokinetic strength and the rate of injuries in the sport., Objectives: The objective of the present study was to investigate the relationship between the isokinetic strength of elite wrestlers and the rate of injuries prospectively., Method: A total of 72 young wrestlers with at least 2 years of experience in the Tehran Wrestling Premier League participated in this study. Before the start of the competition season, the isokinetic strength of flexor and extensor muscles of the knee and shoulder were measured at different velocities by an isokinetic dynamometer. The injuries and training hours of these wrestlers were then recorded for nine months., Results: The study results showed no significant relationship between isokinetic strength of flexor and extensor muscles of the knee or shoulder at different angular speeds of 60, 180, and 300°/s. There was neither significant between the ratio of the strength flexor/extensor for knee and/or shoulder in young elite wrestlers with injuries., Conclusion: Isokinetic strength of lower and upper limb muscles alone cannot predict wrestlers' injuries. Therefore, the use of these tests is not recommended to evaluate the risk of injury in this population., (© 2022. The Author(s).)

Introduction: Depression is a mental disorder that affects more than 250 million people in the world, limiting their functional capacities. The work of public health policies is aimed at reducing its prevalence as well as its pharmaceutical cost. Physical activity (PA) programs are interventions with a high potential for effectiveness., Objectives: To establish the relationships between physical activity and the prevalence of depression and antidepressant intake in the Spanish population., Design: We performed a correlational study that was based on data from the European Health Survey Spain 2020 with 20,287 participants, aged 18-84 years, living in Spain., Results: Dependency relationships were found between the prevalence of depression, and: the frequency of PA, the number of days of PA per week, and the number of days of muscle strengthening in the population, in both sexes, and in all age groups ( p < 0.001). Dependency relationships were found between the three PA variables and the prevalence of taking antidepressants ( p < 0.001). An elevated prevalence of depression and antidepressant taking were found in the inactive groups compared to those who performed PA ( p < 0.05)., Conclusions: There is an inverse relationship between physical activity and the probability of suffering from depression and the intake of antidepressants. Performing PA 3-4 days/week, including 1-2 days of strength work, could be the best proposal to reduce the prevalence of depression in the Spanish population.

Our study examined the effect of 8 weeks of high-intensity interval training (HIIT) and spirulina supplementation on the humoral immunity, cardio-respiratory fitness, and body composition of overweight and obese women. Thirty sedentary women (height: 161.7 ± 2.8 cm, body mass: 75.8 ± 8.4 kg, body mass index [BMI]: 28.8 ± 2.5 kg/m 2 , age: 25.1 ± 6.7 years) were divided into three groups: placebo with HIIT group, spirulina group (SG), or combined group (CG). Exercise groups performed HIIT for 8 weeks, with three sessions per week and four to seven repetitions in each session of 30 s running and 30 s walking; the intensity was established at 90% of the maximum heart rate. Supplementation groups received 6 g of spirulina powder per day. Fasting blood samples were collected before and after 8 weeks to determine the concentrations of immunoglobulins (IgA and IgG). There was a significant group-by-time interaction for fat free mass (FFM; p = 0.001, f = 8.52, ηp 2 = 0.39) and IgA ( p = 0.036, f = 3.86, ηp 2 = 0.22). The post hoc analysis revealed that CG reduced FFM significantly ( p = 0.012, g = -0.55) after training. CG and SG showed significantly greater IgA concentrations after 8 weeks ( p = 0.02, g = 0.70 and p = 0.001, g = 0.34, respectively). We conclude that spirulina supplementation with HIIT affects the body composition (lower FFM) but also boosts IgA, which plays an important role in the immune system.

Introduction: Depression is a challenge for public health policies, as it is the number one leading cause of disability in the world. In order to combat and prevent it, different social and health interventions are being developed to promote health through physical activity., Objective: Analyze and describe the user profile of the patients with depression from the Exercise Looks After You program, which is a physical activity program that works on improving public health and has an essential role preventing chronic diseases and improving the quality of life of the elderly in Extremadura., Design: Cross-sectional study., Participants: total sample of 1972 users (96.4% women, 3.6% men), of whom 724 (94.6% women, 5.4% men) suffer from depression., Results: It was observed that the dominant user profile of the patients with depression within the program is female, 71 years old, physically active, overweight, married, with low educational level, non-smoker, no alcohol consumption and below average physical fitness and health-related quality of life, which translates into a high incidence of primary care, nursing and prescription visits., Conclusions: This study presents the user profile of depressive versus non-depressive participants of the Exercise Looks After You physical activity program. This data could be meaningful in order to improve and optimize public health programs and resources.

Introduction: Depressive disorders are mental disorders that last over time, and seriously affect the lives of the people who suffer from them, diminishing their quality of life, reducing their motor capacity, and incapacitating them in their daily lives. It is a major problem worldwide., Objective: To study the association between agility, health-related quality of life (hrqol), anthropometric status, and depression status in older adult women with depression., Design: Data collected from 685 physically active older women with depression were analyzed., Result: A moderate inverse correlation (r = -0.34) is shown between Time Up & Go (TUG) and EuroQol Five-Dimensional Three-Level Version (EQ-5D-3L). Between TUG and Geriatric Depression Scale (GDS), there is a small direct correlation (r = 0.14) between them. Between TUG and anthropometric data, all observed correlations are significant., Conclusions: There is a significant association between agility, health-related quality of life, depression, and anthropometric data in physically active older women with depression.

Background: Football is the most practised sport in the world and is associated with the risk of injuries in the players. Some studies have been published that identify injury prevention programs, but there is no review of the full body of evidence on injury prevention programs for use by football coaches. The aim of this article was to carry out a systematic review of published studies on injury prevention programs for adult male footballers, identify points of common understanding and establish recommendations that should be considered in the design of injury prevention strategies., Methods: PubMed and EMBASE databases were used to identify relevant published articles using the following keywords: "soccer" AND "injury" AND "prevention"., Results: A total of 2512 studies were identified initially, but only 11 studies met the inclusion criteria, and their outcomes are presented. Results revealed that injury prevention programs in football have focused on strength training, proprioceptive training, multicomponent programs (balance, core stability, and functional strength and mobility), and warm-up programs., Conclusion: Based on results from the studies analyzed, football players can lower the incidence of match and training injuries by participating in dynamic warm-up programs that include preventive exercises before games or during training sessions, and by adding strength, balance, and mobility training to the training sessions., Competing Interests: Competing interests The authors declare they have no competing interests., (Copyright © 2020.

Background: Regucalcin, or senescence marker protein-30 (SMP30), is a Ca 2+ -binding protein with multiple functions reported in the literature. Physical exercise has been shown to improve aging markers; nevertheless, SMP30 in humans has not been extensively researched. Older adults experience a decline in functional capacity and body composition. The purpose of this study was to examine the effects of a multicomponent training (MCT) program on SMP30 and its regulation of walking ability and body composition in functionally limited, frail, and pre-frail older adults., Methods: A total of 34 older adults (aged 80.3 ± 6.1 years) were divided into an intervention group (IG = 20) and control group (CG = 14). The IG performed a supervised MCT (strength, endurance, balance, coordination, and flexibility) program for 6 months, 3 days per week, whereas the CG continued their normal lives without any specific physical training. SMP30 was analyzed in plasma after 3 and 6 months of MCT, while some physical fitness variables (Timed Up and Go (TUG) and 6-min walk test (6MWT)) and body composition (fat mass and lean mass) were measured at baseline, as well as after 3 months and 6 months of MCT., Results: No significant changes were observed in SPM30 between the IG (877.5 a.u. to 940.5 a.u., respectively) and CG (790.4 a.u. to 763.8 a.u., respectively). Moreover, no SMP30 differences were found between groups after 3 and 6 months of MCT. The IG improved significantly in the 6MWT after 3 months (472.2 ± 84.2 m) compared to baseline (411.2 ± 75.2 m). The IG also significantly enhanced their TUG performance after 3 months (7.6 ± 1.6 s) and 6 months (7.3 ± 1.8 s) of training compared to baseline (9.3 ± 3.2 s) (all, p < 0.001). There were no significant differences in body composition between the IG and CG through the 6 months of MCT., Conclusions: The present study suggests that MCT did not change SMP30 levels from 3 to 6 months, where there were changes in neither walking ability nor body composition; however, MCT was effective in improving 6MWT and TUG performance from baseline to 3 months.

Free radicals are reactive products that have multiple effects on the human body. Endogenous and exogenous antioxidants manage the overproduction of free radicals. However, an imbalance between free radicals and antioxidant factors causes oxidative stress. Exercise and physical activity are factors that increase oxidative stress and disrupts the body's homeostasis. Intensity and duration of training, training characteristics, and fitness level can have positive or negative effects on oxidative stress. Green tea consumption is recommended for the prevention of a variety of diseases, health maintenance, and weight loss. The effectiveness of green tea is primarily due to the presence of catechins and polyphenols, specifically (-)-epigallocatechin-3-gallate, which has antioxidant and anti-inflammatory properties based on clinical and animal studies. This review investigates the effect of green tea exercise and their interactive effects on free radicals and sports improvement.

Background: This study aims to assess the effects of 8 weeks of plyometric jump training (PJT) conducted on sand or a rigid court surface on jump-related biomechanical variables and physical fitness in female indoor volleyball players., Methods: Seventeen participants were randomly divided into a sand surface group (SsG, n = 8) and rigid surface group (RsG, n = 9). Both groups completed equal indoor volleyball training routines. Participants were assessed pre and post the 8-week PJT for jump-related biomechanical variables (countermovement jump (CMJ) RSI; drop jump (DJ) reactive strength index (RSI); spike jump (SJ) height; CMJ height; CMJ rate of force development (RFD); CMJ velocity at take-off; DJ height and CMJ peak force), 20 m linear sprint time, t test for change-of-direction sprint (CODs) time, Wingate test peak power (PP), cardiorespiratory endurance, and leg-press one-repetition maximum (1RM)., Results: A two-way mixed analysis of variance (group × time) revealed that there was a significant group × time interaction between DJ height ( p = 0.035) and CMJ peak force ( p = 0.032) in favour of RsG and SsG, respectively. A significant interaction was also observed for cardiorespiratory endurance ( p = 0.01) and 1RM ( p = 0.002), both favouring the SsG. No other group × time interaction was observed., Conclusions: The type of surface used during PJT induced specific adaptations in terms of jump-related biomechanical variables and physical fitness in female indoor volleyball players. Based on the individual needs of the athletes, practitioners may prescribe one type of surface preferentially over another to maximize the benefits derived from PJT.

The aims of this study were to compare the external intensity between official (OMs) and friendly matches (FMs), and between first and second halves in the Iranian Premier League. Twelve players participated in this study (age, 28.6 ± 2.7 years; height, 182.1 ± 8.6 cm; body mass, 75.3 ± 8.2 kg). External intensity was measured by total duration, total distance, average speed, high-speed running distance, sprint distance, maximal speed and body load. In general, there was higher intensity in OMs compared with FMs for all variables. The first half showed higher intensities than the second half, regardless of the type of the match. Specifically, OMs showed higher values for total sprint distance ( p = 0.012, ES = 0.59) and maximal speed ( p < 0.001, ES = 0.27) but lower value for body load ( p = 0.038, ES = -0.42) compared to FMs. The first half of FMs only showed lower value for body load ( p = 0.004, ES = -0.38) than FMs, while in the second half of OMs, only total distance showed a higher value than FMs ( p = 0.013, ES = 0.96). OMs showed higher demands of high intensity, questioning the original assumption of FMs demands. Depending on the period of the season that FMs are applied, coaches may consider requesting higher demands from their teams.

The aimed to evaluate the effects of low and moderate-intensity aerobic exercise on psychological well-being (PWB) and quality of life (QoL) among older people. Forty-five male Iranian adults aged 65-80 years were selected according to the eligibility criteria and randomly assigned to a low-intensity group (LIG) (40-50% of maximum heart rate), moderate-intensity group (MIG) (60-70% of maximum heart rate) and control group (CG). The exercise protocols consisted of 12 weeks of aerobic exercise (two sessions per week). Psychological well-being and QoL were assessed through the Ryff's Psychological Well-being Scale and the World Health Organization QoL Questionnaire. The statistical analysis for psychological well-being indicated that a significant main group (between-group) ( F = 11.777, p < 0.001, η p 2 = 0.359), time (within-group) ( F = 58.983, p < 0.001, η p 2 = 0.584) and interaction effect (group × time) ( F = 20.146, p < 0.001, η p 2 = 0.490) for PWB total score. Bonferroni post-hoc tests revealed that the PWB total score in the MIG group was more significant than both LIG ( p = 0.003) and CG ( p < 0.001). Results for PWB components including self-acceptance, positive relationships with others, autonomy, purposeful life, and environmental mastery revealed no significant differences ( p > 0.05). While there was a significant difference between the groups for personal growth component. Bonferroni post-hoc tests revealed that the personal growth in the MIG group was more significant than both LIG ( p = 0.028) and CG ( p < 0.001). Result for QoL indicated significant differences for the main group ( F = 13.277, p < 0.001, η p 2 = 0.387), time ( F = 25.533, p < 0.001, η p 2 = 0.378) and interaction effect ( F = 9.992, p < 0.001, η p 2 = 0.332) for QoL total scale. Bonferroni post-hoc tests revealed that the QoL total scale in the MIG group was more significant than both LIG ( p = 0.003) and CG ( p < 0.001). Results for QoL components including Physical health, Social relationships, Health environment revealed no significant differences ( p > 0.05), while there was a significant difference between the groups for the Psychological health component. Bonferroni post-hoc tests revealed that the Psychological health in the MIG group was more significant than both LIG ( p = 0.009) and CG ( p = 0.002). Therefore, aerobic exercise improves PWB and QoL in older adults, moderate-intensity exercise seems to produce higher benefits than low-intensity, demonstrating a positive dose-response relationship., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Shams, Nobari, Afonso, Abbasi, Mainer-Pardos, Pérez-Gómez, Bayati, Bahrami and Carneiro.)

Background: Due to the vulnerability to protective and risk factors during adolescence, there is a growing interest in the study of health-related quality of life (HRQoL) at this stage. The CHU9D is a generic and practical HRQoL instrument that provides values on all dimensions of self-perceived health, in addition to providing utilities and a cost-utility assessment fee, unlike other instruments. This study was conducted with an adolescent population in Peru. The main objective of this article is to report the normative values of the CHU9D questionnaire in Peruvian adolescents., Methods: The CHU9D questionnaire was administered to Peruvian adolescent students. A total of 1229 young people participated in the survey. The CHU9D score was reflected as a function of gender, age, weight, height, and educational level., Results: The mean CHU9D utility index for the total sample was 0.890; this rating was significantly better for boys with 0.887 and girls with 0.867. The ceiling effect was higher for male adolescents with 32.6 than for female adolescents., Conclusions: The results of the present study show that adolescents in school show a positive perception of HRQoL. It is also concluded that the CHU9D instrument can be effectively applied to economic evaluations for interventions to improve the quality of life of adolescents.

WHAT IS KNOWN ON THE SUBJECT?: Attention-deficit/hyperactivity disorder (ADHD) is characterized by problems of inattention and impulsive hyperactivity in children. Equine-assisted activities and therapies (EAATs) have been used as alternative non-pharmacological intervention option in patients with ADHD. WHAT DOES THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Nowadays, more studies of high methodological quality are needed to determine whether EAAT is an effective intervention for the treatment in children with ADHD. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Between 15 and 40 min of rising horses, 8-32 total sessions, for 4-32 weeks, seem to be beneficial to reduce the symptoms of ADHD., Abstract: INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is a disorder characterized by problems of inattention and impulsive hyperactivity. Equine-assisted activities and therapies (EAATs) have become an emerging non-pharmacological intervention option in patients with ADHD., Aim: To perform a systematic review of updated literature about EAAT in children with ADHD., Method: A systematic review was performed until 28 November 2019, in four electronic databases: PubMed, Web of Science, Embase and Google Scholar. The inclusion criteria were as follows: (a) intervention programme, with pre- and post-data, based on EAAT, (b) children with ADHD and (c) articles written in English., Results: A total of 9 articles were found that meet the inclusion criteria. The evidence level was C for 7 studies and B for 2 studies. The level of conclusion was 3., Discussion: There are few studies with high methodological quality, and there is a high heterogeneity in the variables included, what make that the level of evidence and conclusion are low., Conclusion: There is no account with enough studies of high methodological quality to determine whether EAAT is an effective intervention for the treatment in children with ADHD., (© 2020 John Wiley & Sons Ltd.)
