This pilot study assessed the physical and psychological outcomes of a tai chi exercise program for eight adults with visual impairments. It found that after eight weeks of orientation and mobility training and tai chi practice, the participants' single leg-stance time and total knee flexion work and power improved, as did their frequency of, independence in, and satisfaction with performing mobility tasks.

Exercise therapy is the first-line intervention recommended for those with chronic musculoskeletal pain (CMP). Smartphone technologies (mHealth) represent a feasible means for exercise prescription and individualization. This systematic review with meta-analysis aimed to identify factors associated with changes in pain and function following mHealth-based exercise therapy in patients with CMP. CINAHL (via EBSCOhost), Embase, PubMed, Scopus, and SPORTdiscus were searched from inception to February 2023. Observational and controlled clinical trials with correlation or regression analysis of factors associated with the effect of mHealth exercise interventions on pain and function were included. The risk of bias, completeness of interventions, spin of information, and certainty in the evidence were evaluated. Eight studies with 51,755 participants were included. Reduced pain intensity after intervention was associated with higher physical function: r (95% CI) = −0.55 (−0.67 to −0.41); I2 = 86%, Tau2 = 0.02; p < 0.01. Meta-regression identified the Body Mass Index (BMI), exercise dose, and completion rate as potential moderators between changes in pain and physical function following mHealth exercise therapy. No association was found between pain and anxiety: r (95% CI) = 0.15 (−0.08 to 0.37); I2 = 87%, Tau2 = 0.02; p = 0.19. Very low certainty in the evidence was observed due to serious concerns regarding the risk of bias, inconsistency, and indirectness. The limited available evidence detracts from the clinical interpretation of the findings. [ABSTRACT FROM AUTHOR]

Background: Pre-frailty is associated with increased healthcare utilization. Over the past decade, public health interventions such as community-based exercises to target pre-frailty have been increasingly studied. However, the effects of community-based exercises on clinical outcome measures amongst community-dwelling older adults with pre-frailty remain unclear. This review aims to better understand the effects of community-based exercise on physical function, cognition, quality of life and frailty status in community-dwelling pre-frail older adults. A secondary objective was to investigate the optimal exercise parameters on clinical outcomes. Methods: Searches of MEDLINE, CINAHL, Google Scholar and Web of Science databases were conducted. Articles were included if they were randomized controlled trials (RCTs), and excluded if the participants consist of less than 50% pre-frail community-dwelling older adults. Meta-analyses (where possible) with either a fixed- or random- effect(s) model, standardized mean difference (SMD), odds ratio (OR) and tests of heterogeneity were performed. Multivariable meta-regression was performed to identify predictors of statistically significant outcome measures. The risk of bias was assessed using the modified Cochrane Risk-of-Bias tool. Results: Twenty-two RCTs with 900 participants in the experimental group and 1015 participants in the control group were included. When compared to minimal intervention, community-based exercises significantly improved lower limb strength (10 RCTs, 384 participants in the experimental group and 482 participants in the control group) with SMD 0.67 (95% CI 0.29 to 1.04), and lower limb function (5 RCTs, 120 participants in the experimental group and 219 participants in the control group) with SMD 0.27 (95% CI 0.03 to 0.51). Those who have received community-based exercises were more likely to reverse from pre-frailty to healthy state (OR = 2.74, 95% CI 1.36 to 5.51) (6 RCTs, 263 participants in the experimental group and 281 participants in the control group). The frequency of exercise sessions was a significant predictor of the effect size for gait speed (P<0.05). Conclusions: Community-based exercise intervention is superior to minimal intervention for improving health status in pre-frail older adults. This has implications on the implementation of community-based exercise intervention by healthcare providers and policymakers. Other: Nil funding for this review.

Objective: To evaluate the effects of comprehensive exercise training on frailty, negative emotions and physical functions of elderly patients with diabetes. Methods: This is a retrospective study. A total of 140 elderly patients with T2DM in The No.2 Hospital of Baoding were selected from December, 2021 to June, 2023 and randomly divided into two groups, with 70 patients in each group. The control group was given routine nursing and routine exercise education, and the study group was additionally given comprehensive exercise training. Tilburg frailty indicator (TFI), emotional status, physical functions, grip strength, fasting blood glucose and patient satisfaction were compared and analyzed between the two groups. Results: Before the intervention, TFI showed no significant differences between the two groups (p>0.05). After the intervention, physical, psychological and social frailty in the study group were significantly lower than those in the control group, with statistically significant differences (p= 0.00). SAS and SDS scores reduced significantly in the study group compared with those in the control group after the intervention, with statistically significant differences (p=0.00). After the intervention, the grip strength was significantly larger while the fasting blood glucose was significantly lower in the study group compared with those in the control group, with statistically significant differences (p=0.00). Patient satisfaction in the study group was higher than in the control group, with a statistically significant difference(p=0.03). Conclusion: Comprehensive exercise training for elderly patients with diabetes is beneficial to improving their frail state, negative emotions, blood glucose levels and physical functions. It has significant clinical application value. [ABSTRACT FROM AUTHOR]

In people with Parkinson's disease, what is the effect of adding external cueing (ie, visual, auditory or somatosensorial cueing) to walking training compared with walking training alone in terms of walking, mobility, balance, fear of falling and freezing? Are any benefits carried over to participation or maintained beyond the intervention period? Systematic review of randomised trials with meta-analysis. Ambulatory adults with Parkinson's disease. Walking training with external cueing compared with walking training without external cueing. Walking (ie, speed, stride length and cadence), mobility, balance, fear of falling, freezing and participation. Ten trials involving a total of 309 participants were included. The mean PEDro score of the included trials was 5 (range 4 to 8). Walking training with auditory cueing improved walking speed by 0.09 m/s (95% CI 0.02 to 0.15) more than walking training alone. Although the best estimate was that auditory cueing may also improve stride length by 5 cm, this estimate was imprecise (95% CI –2 to 11). The addition of visual cueing to walking training did not improve walking speed or stride length. Results regarding cadence, mobility, balance, fear of falling, and freezing and maintenance of benefits beyond the intervention period remain uncertain. This systematic review provided low-quality evidence that walking training with auditory cueing is more effective than walking training alone for improving walking speed in Parkinson's disease. Cueing is an inexpensive and easy to implement intervention, so the mean estimate might be considered clinically worthwhile, although the confidence interval spans clinically trivial and worthwhile effects.

Anaerobic exercise decreases systemic pH and increases metabolic acidosis in athletes, altering the acid-base homeostasis. In addition, nutritional recommendations advising athletes to intake higher amounts of proteins and simple carbohydrates (including from sport functional supplements) could be detrimental to restoring acid-base balance. Here, this specific nutrition could be classified as an acidic diet and defined as 'Westernized athletic nutrition'. The maintenance of a chronic physiological state of low-grade metabolic acidosis produces detrimental effects on systemic health, physical performance, and inflammation. Therefore, nutrition must be capable of compensating for systemic acidosis from anaerobic exercise. The healthy gut microbiota can contribute to improving health and physical performance in athletes and, specifically, decrease the systemic acidic load through the conversion of lactate from systemic circulation to short-chain fatty acids in the proximal colon. On the contrary, microbial dysbiosis results in negative consequences for host health and physical performance because it results in a greater accumulation of systemic lactate, hydrogen ions, carbon dioxide, bacterial endotoxins, bioamines, and immunogenic compounds that are transported through the epithelia into the blood circulation. In conclusion, the systemic metabolic acidosis resulting from anaerobic exercise can be aggravated through an acidic diet, promoting chronic, low-grade metabolic acidosis in athletes. The individuality of athletic training and nutrition must take into consideration the acid-base homeostasis to modulate microbiota and adaptive physiological responses. [ABSTRACT FROM AUTHOR]

Optimal physical fitness is essential for military personnel to effectively meet their rigorous physical demands. This study aimed to investigate the effectiveness of a suspension training program on physical fitness, biomechanical risk factors for lower extremity injury, mental health, and work-related factors in Navy personnel. A total of 50 young men participated in a randomized controlled trial. The participants were randomly assigned to two groups (n = 25): the intervention group and the control group. The intervention group performed an eight-week suspension training session three times per week, while the control group maintained their daily duties. The primary outcome was physical performance. The secondary outcomes were determined biomechanical risk factors for lower extremity injuries, mental health, and work-related factors. The data were analyzed using the analysis of covariance (ANCOVA). Compared with the control group, the intervention group showed significant improvements in physical performance, biomechanical risk for lower extremity injuries, and work-related factors from baseline to follow-up (p ≤ 0.05). However, there was no improvement in mental health. Based on these findings, suspension training positively impacted physical fitness, reduced injury risk, and enhanced the work-related factors of Navy personnel. This study provides new insights for various related experts and military coaches because it is an easy-to-use and feasible method with minimal facilities. [ABSTRACT FROM AUTHOR]

The present study focused on the effects of a physical training program on physical- and psychological-related variables in professional esports players. Five professional League of Legends (LOL) players belonging to the highest national category participated in this study. Data were obtained before and after a 5 h virtual training session (acute), as well as before and after an 8-week intervention period, focused on decreasing the impact of fatigue on players' health and performance. The results showed that a complete virtual training session influences their performance, decreasing jump height and joint mobility (p < 0.01), as well as increasing perceived physical and cognitive exertion by 76.9% (p < 0.01) and 166.67% on the "Rating of Fatigue" scale (p = 0.002). Moreover, the intervention was able to reduce the impact of fatigue (30.8% and 43.3% reduction in cognitive and overall fatigue, respectively, p < 0.05), improving, at the same time, the amount of muscle mass by 2%, jumping ability by 9.8% to 21%, and strength levels in various exercises by 63% to 173% (p < 0.01). The implementation of a physical training program is capable of reducing the players' fatigue perception, improving their physical conditioning and health status, and decreasing the injury risk.

Introduction: With our rapidly expanding population of older adults, identifying effective intervention strategies to improve cognitive functioning is an increasing priority. This study sought to examine whether 4 weeks of thrice-weekly meditation training can improve attention in older adults, as well as whether such benefits may extend to other domains of cognition as well as mobility. Methods: Forty-three participants (mean age 68 years) were randomized into either the focused attention meditation group or the music listening control group (Clinicaltrials.gov ID NCT03417635). Participants completed three 20- minute guided group sessions per week for four consecutive weeks. Our primary outcome measure was behavioural performance on the Sustained Attention to Response Task (SART). Secondary and tertiary outcome measures included event-related potentials (ERPs) during the SART task, measures of executive functioning, and measures of mobility. Results: We found that meditation training significantly improved attention, as demonstrated by improved SART accuracy and changes in N2 ERP amplitude and latency. Discussion: These findings suggest that meditation may lead to changes in attention and underlying cognitive processing in older adults, although a fullscale definitive trial is needed. Future research on the long-term benefits with real world applications is warranted. [ABSTRACT FROM AUTHOR]

Purpose: Although several studies investigated the effect of plyometric training on physical performance, there is a lack of clarity regarding the effectiveness of plyometric training or its moderator variables in youth female volleyball players. The primary aim of this study was to explore the effect of horizontal plyometric training on explosive stretch-shortening cycle hops and jumps in the vertical and horizontal directions in female post peak height velocity (PHV) volleyball players. The secondary aim was to assess the influence of participant and training related moderators on horizontal plyometric training in post-PHV volleyball players. Methods: A total of 23 post-PHV volleyball players participated in this 8-week intervention with horizontal plyometric exercises, twice a week. Pre-testing and post-testing included bilateral and unilateral vertical sub-maximal hopping, horizontal jumping and hopping, and a drop jump test. The effectiveness of the intervention was assessed using a paired t-test. The influence of internal moderators such as age, maturity and body mass and external moderators such as training volume were assessed using regression and correlation analysis. Results: An 8-week plyometric training improved sub-maximal hopping at 2.5 Hz left by 4.4%, bilateral sub-maximal hopping at 2.0 Hz by 9.5% and bilateral submaximal hopping at 2.2 Hz by 6.8% in post-PHV female volleyball players. Horizontal jumping and hopping, reactive strength index and other submaximal hopping conditions did not improve significantly. Body mass had a large moderating effect on vertical unilateral sub-maximal hopping at 2.5 Hz right (p = 0.010, η² = 0.314), vertical unilateral hopping at 3.0 Hz right (p = 0.035, η² = 0.170), and vertical unilateral hopping at 3.0 Hz left (p = 0.043, η² = 0.203). Training volume together with generalized joint hypermobility moderated right leg triple broad hop performance, whereas maturity and age did not moderate any variables. Conclusion: This study determined that 8 weeks of horizontal plyometric training can improve unilateral absolute leg stiffness in post-PHV female volleyball players, and this training effect can be moderated by body mass. Furthermore, the training effect on triple hopping performance on the right leg can be moderated by combined training volume with generalized joint hypermobility. [ABSTRACT FROM AUTHOR]

Age‐related alterations in physiology lead to declines in physical function that are associated with numerous adverse outcomes among older adults. Utilizing a hybrid design, we aimed to understand whether both long‐term and short‐term Tai Chi (TC) training are associated with age‐related decline in physical function in healthy older adults. We first conducted cross‐sectional comparisons among TC‐naïve older adults (n = 60, 64.2 ± 7.7 years), TC‐expert older adults (n = 27, 62.8 ± 7.6 years, 24.5 ± 12 years experience), and TC‐naïve younger adults (n = 15, 28.7 ± 3.2 years) to inform long‐term effects of TC training on physical function, including single leg stance time with eyes closed, grip strength, Timed Up and Go, maximum walking speed, functional reach, and vertical jump for lower‐extremity power. There were significant differences among the three groups on all the six tests. For most functional tests, TC‐experts performed better than age‐matched TC‐naïve controls and were statistically indistinguishable from young healthy adult controls. Long‐term TC training was associated with higher levels of physical function in older adults, suggesting a potential preventative healthy aging effect. In the randomized longitudinal trial, TC‐naïve subjects were randomized (n = 31 to Tai Chi group, n = 29 to usual care control group) to evaluate the short‐term effects of TC over 6 months on all outcomes. TC's short‐term impacts on physical function were small and not statistically significant. The impact of short‐term training in healthy adults is less clear. Both potential longer‐term preventive effects and shorter‐term restorative effects warrant further research with rigorous, adequately powered controlled clinical trials. [ABSTRACT FROM AUTHOR]

Background: When compared to children without Down syndrome (DS), children with DS exhibit qualitatively different movement patterns and a considerable delay in the development of motor abilities. Due to their difficulty maintaining proper body alignment and aberrant walking patterns, children with DS are more likely to fall. Strengthening and aerobic exercise are part of the Down syndrome therapy programme. Purpose: To evaluate the effectiveness of aerobic exercises and strengthening exercises in Down Syndrome Population. Methodology: Twenty down syndrome patients were randomly divided into groups A and B. Aerobic exercise was given to ten subjects in group A, and strengthening exercise was given to ten subjects in group B. The Dynamic Gait Index Scale was employed as an outcome measure and was pre-assessed on Day 1. For four weeks of treatment, each group had two sessions per day, followed by a post-assessment of the outcome measures. Results: Group A experienced an increase in the dynamic gait index scale. The Group A showed improvement in the Dynamic gait index scale after training, which was statistically significant (p<.01) Conclusion: The results obtained from this research were statistically classified and can be concluded that there was a definite and positive effect of strengthening exercise in improving functional mobility in Down syndrome population.

Regular physical activity (PA) has numerous physical and mental health benefits, including reducing the risk of cardiovascular disease (CVD), chronic kidney disease (CKD), and cancer. However, a significant portion of the global adult population does not meet the recommended guidelines for weekly PA. In Portugal, only a small percentage of youth, adults, and older adults meet these guidelines. Physical exercise, a subset of PA, has been shown to have profound health benefits for individuals with chronic diseases. Despite the evidence supporting the role of PA in preventing and managing chronic diseases, efforts to promote PA and integrate it into routine clinical care have been largely unsuccessful. It is important for healthcare providers and public health stakeholders to prioritize the integration of PA into treatment plans and to take action to promote PA for better health management.

Background: Neuromuscular training (NMT) has demonstrated efficacy as an intervention to decrease the risk of anterior cruciate ligament injuries and improve sports performance. The effect of this training on the mechanisms that contribute to improved physical performance has not been well defined. Hypothesis: Athletes in the NMT group will have better mechanisms of fundamental movements and agility tests that may contribute to improved sports performance. Study Design: Prospective cohort study Level of Evidence: Level 2 Methods: Eight high school teams (111 athletes, 53% male, mean age 16 years) participated, with half performing NMT. Physical performance was measured using the dorsaVi ViPerform system, a US Food and Drug Administration-cleared wireless sensor system. Agility was assessed using a timed 3-cone test. Independent sample t tests were used to compare differences between the intervention and control groups. Results: Matched pre- and postseason data were collected from 74 athletes after excluding athletes with injury and those lost to follow-up. Significant improvements were observed in the NMT group for loading/landing speed ratios during a single-leg hop test (right lower extremity = −0.19 [–0.37, 0.03], P = 0.03 and left lower extremity = −0.27 [–0.50, −0.03], P = 0.03). The control group had lower ground reaction forces compared with the NMT group (P < 0.02), while significant improvements were found in the NMT group for initial peak acceleration (P < 0.02) and cadence (P = 0.01) during a straight-line acceleration/deceleration test. For the 3-cone agility test, the postseason time decreased compared with preseason in the NMT group, whereas the time for the control group increased (–0.37 s vs 0.14 s, P < 0.00). Conclusion: The results demonstrate that NMT administered by sports medicine clinicians can significantly improve some physical performance of fundamental movements in high school athletes. Clinical Relevance: Coaches should be trained to effectively deliver NMT in order to improve sports performance. [ABSTRACT FROM AUTHOR]

This systematic review aimed to assess the available evidence on the effects of neuromuscular training on physical performance in older adults. A literature search was conducted across four databases (Psychology and Behavioral (EBSCO), Scopus, Web of Science and PubMed). The PRISMA guidelines were followed. The PEDro scale and Cochrane risk of bias tool were used to assess the quality of and risk of bias in the studies, respectively. The protocol was registered in PROSPERO (code: CRD42022319239). The outcomes were muscle strength, cardiorespiratory fitness, postural balance and gait speed. From 610 records initially found, 10 were finally included in the systematic review, involving 354 older people with a mean age of 67.3 years. Nine of them reported significant changes in at least one variable related to physical performance in the intervention compared to the control groups. The neuromuscular training caused significant improvements in postural balance, flexibility, cardiorespiratory fitness, strength power of the upper and lower limbs and autonomy. The available evidence indicates that neuromuscular training has a positive effect on some variables of physical performance, especially in postural balance; however, the methodological quality and certainty of the evidence in the available literature are limited. Therefore, a greater number of high-quality studies are required to draw definitive conclusions. [ABSTRACT FROM AUTHOR]

Background: Patients who suffer from diabetic peripheral neuropathy in the lower leg experience a greater risk of falls due to a decrease in strength of the lower extremities. Methods: Fourteen participants, diagnosed with diabetic peripheral neuropathy or nocturnal allodynia in either one or both extremities, volunteered to participate in this study. Participants were purposively selected from two private Podiatry practices based on their signs and symptoms, age, gender, and doctor's clearance to participate in any form of physical activity. Dependent variables included isometric muscle strength of the hip, knee and ankle, range of motion of the ankle in plantarflexion and dorsiflexion and an assessment of balance, which were measured pre- and post-intervention. The researcher developed a scientifically based exercise intervention program to target the entire kinetic chain, and to develop a standard isometric protocol for patients with DPN. The intervention program consisted of a combination of ankle, hip, and knee specific rehabilitation. The intervention took place 3 times a week for 45 min per session. Results: The Mann-Whitney test was used to evaluate the differences in dependent variables from pre- to post-intervention. The level of significance was set at p<0.05. Notable increases were observed in range of motion in ankle plantarflexion and in balance time in the intervention group, post-intervention. Conclusions: Although many of the changes noted were insignificant, the trends indicated an improvement in the intervention group over the 10-week intervention period. These improvements can be considered clinically important. [ABSTRACT FROM AUTHOR]

In recent years, there has been an explosion of new approaches (technological, methodological, pharmacological, etc.) designed to improve physical performance for athletes, the military and in other applications. The goal of the present discussion is to review and quantify several ways in which physiology can provide important insights about which tools may lead to improved performance (and may therefore be worth resource investment) and which tools are less likely to provide meaningful enhancement. To address these objectives, we review examples of technological solutions/approaches in terms of the magnitude of their potential (or actual) influences: transformational, moderate, ineffective or undetermined. As one example, if there were a technology which significantly increased arterial oxygen partial pressure by 10%, this would be relatively meaningless in healthy people resting at sea level, where it would have a minimal effect on arterial oxygen content. However, there might be specific situations where such an effect would be very helpful, including at high altitude or in some patient populations. We discuss the importance of quantitative evaluation of putative approaches to performance enhancement and highlight the important role of integrative physiologists in the development and critical appraisal of these approaches.

Objectives: As a major feature of the disease, motor-related complications, including loss of balance and reduced ability to walk were seen in multiple sclerosis (MS). The purpose of this study was to investigate the effect of core stability exercises and transcranial directcurrent stimulation (tDCS) as a non-invasive brain stimulation on balance, walking capacity, and quality of life in patients with MS. Methods: In this randomized clinical trial study with a pretest-posttest design, 29 female patients with an Expanded Disability Status Scale (EDSS) of less than 4.5 (3.75±1.31) and a mean age of 38.36±7.99 years were purposefully selected from patients referring to MS society of Tehran during 2021 and then randomly assigned to the following three groups: core stability exercises, anodal tDCS, and sham. Variables, such as balance, walking capacity, and quality of life were measured before and after the interventions. Subjects in the core stability training group participated in core stability exercises for three weeks, and subjects in both sham and anodal tDCS groups received direct brain electrical stimulation for five sessions. Results: A significant improvement in balance and walking capacity were seen both in the anodal tDCS and the core stability training groups (P<0.05). Moreover, mobility was significantly changed in the tDCS group (P<0.05). However, no significant difference in the quality of life was seen between the groups. Discussion: Our findings indicate comparable effects of tDCS, and core stability training on balance and walking capacity in patients with MS. Therefore, in addition to exercises, tDCS can be considered a promising tool for the neurorehabilitation of patients with MS. [ABSTRACT FROM AUTHOR]

Background: Lewy body dementia (LBD) is an aggressive type of dementia of rapid, fluctuating disease trajectory, higher incidence of adverse events, and poorer functional independence than observed in Alzheimer's disease dementia. Non-pharmacological treatments such as progressive, high-intensity exercise are effective in other neurological cohorts but have been scarcely evaluated in LBD.Methods: The Promoting Independence in Lewy Body Dementia through Exercise (PRIDE) trial was a non-randomised, non-blinded, crossover pilot trial involving older adults with LBD consisting of a baseline assessment, an 8-week wait-list, and an 8-week exercise intervention. The aims of this study were to evaluate the determinants of the primary outcome functional independence, as measured by the Movement Disorder Society Unified Parkinson's Disease Rating Scale, and the feasibility and preliminary efficacy of an exercise intervention on this outcome. Additionally, important clinical characteristics were evaluated to explore associations and treatment targets. The exercise intervention was supervised, clinic-based, high-intensity progressive resistance training (PRT), challenging balance, and functional exercises, 3 days/week.Results: Nine participants completed the baseline cross-sectional study, of which five had a diagnosis of Parkinson's disease dementia (PDD), and four dementia with Lewy Bodies (DLB). Six completed the exercise intervention (three PDD, three DLB). The cohort was diverse, ranging from mild to severe dementia and living in various residential settings. Greater functional independence at baseline was significantly associated with better physical function, balance, cognition, quality of life, muscle mass ratio, walking endurance, faster walking speed and cadence, and lower dementia severity (p < 0.05). Participants declined by clinically meaningful amounts in functional independence, cognition, physical function, muscle mass, and weight over the wait-list period (p < 0.05). Following exercise, participants improved by clinically meaningful amounts in functional independence, cognition, physical function, and strength (p < 0.05). Progressive, high intensity exercise was well-tolerated (> 80% adherence), and only one minor exercise-related adverse event occurred.Conclusions: PRIDE is the first exercise trial conducted specifically within individuals diagnosed with LBD, and provides important insight for the design of larger, randomized trials for further evaluation of progressive, high-intensity exercise as a valuable treatment in LBD.Trial Registration: The PRIDE trial protocol has previously been prospectively registered (08/04/2016, ANZCTR: ACTRN12616000466448).

Background: The benefits of resistance training for patients with type 2 diabetes (T2D) are well documented; however, the effects of exercise with different muscle contraction types such as eccentric versus concentric contractions on physiological outcomes for this population are not clear. This study compared eccentric-only (ECC) and concentric-only resistance training (CON) to test the hypothesis that ECC would be superior to CON to improve insulin sensitivity, lipid profile, body composition, muscle strength and physical function of patients with T2D. Methods: Adults with T2D (50–79 years) were allocated to the ECC (n = 9) or CON group (n = 9). Resistance exercises (chest press, lateral pulldown, bicep curl, triceps extension, leg extension, leg curl, calf raise, abdominal crunch) consisting of 2–3 sets of 10 eccentric-only (5 s) or concentric-only contractions (1–2 s) was performed twice a week for 12 weeks. Changes in blood biomarkers, body composition, muscle strength and physical function from pre- to post-intervention were compared between groups. Results: Overall rating of perceived exertion (RPE, 1–10 Borg scale) was lower (p < 0.05) for ECC (2.9 ± 1.2) than CON (5.4 ± 1.1). No significant changes in blood biomarkers were found for both groups. Lean mass increased [effect size (ES) = 0.148, ECC 3.2 ± 6.9%; CON 3.6 ± 2.3%], and fat mass decreased (ES = 0.545, ECC − 6.1 ± 12.4%; CON − 7.1 ± 16.4%) (p < 0.05) similarly. One-repetition maximal strength of each exercise increased (p < 0.05) for both ECC (12–37%) and CON (27–68%). Both groups improved (p < 0.05) 6-min walk distance (ES = 0.083, ECC 12.2 ± 2.3%; CON 12.5 ± 15.3%) and chair rise time (ES = 0.463, ECC − 13.4 ± 25.4%; CON − 20.0 ± 53.3%) but only ECC improved (p < 0.05) the timed up-and-go test (− 11.3 ± 13.6%, ES 0.014). No significant changes in balance tests were found for both groups. Conclusion: These results did not fully support the hypothesis but showed that ECC was as effective as CON to improve body composition, muscle strength, and physical function with lesser RPE. Future studies should investigate whether larger differences between ECC and CON are evident when increasing the exercise frequency and matching the intensities of the two-exercise protocols.

This meta-analytical review aimed at comparing the impact of Pilates interventions (PIs) on physiological and psychological health parameters in healthy older adults and older adults with a clinical condition aged 55 years and older. The literature search was conducted in three databases (PubMed, Web of Science, SPORTDiscus). Randomized controlled trials that aimed at improving physiological and psychological health parameters in adults aged 55 years and older using Pilates as an intervention were screened for eligibility. The included data was extracted and assigned based on participants' health condition (clinical vs. non-clinical), as well as the respective control condition used in the study [inactive (IC) vs. active control group (AC)]. Statistical analyses were computed using a random-effects inverse-variance model. Fifty-one studies with a total of 2,485 participants (mean age: 66.5 ± 4.9 years) were included. Moderate effects (SMD: 0.55; 0.68) were found for physiological health parameters (muscle strength, balance, endurance, flexibility, gait, and physical functioning) in both experimental (clinical and non-clinical) conditions when compared to ICs (p < 0.003; p = 0.0001), and small to moderate effects (SMD: 0.27; 0.50) when compared to ACs (p = 0.04; p = 0.01). Moderate to large effects (SMD: 0.62; 0.83) were documented for psychological health parameters (quality of life, depression, sleep quality, fear of falling, pain, and health perception) in both conditions when compared to ICs (p < 0.001, p < 0.001). PIs induce small to large effects in physiological and psychological health parameters in older adults, regardless of their health condition. The substantial heterogeneity within the included studies complicated standardized comparison of the training modalities between the two target groups. Nonetheless, Pilates seems to be a safe, adaptable, and promising exercise approach for a heterogenous population of older adults. [ABSTRACT FROM AUTHOR]

Background: Impairment in the ability to perform another task while walking i.e., dual tasking is associated with an increased risk of fall, diminished mobility, loss of independence leading to decrease in the quality of life among patients with Parkinson's disease. So, the present study aims to determine the retention effect of dual task training on mobility, fear of fall, quality of life. Method: 30 subjects between the age group of 65-75 years diagnosed with PD were included in the study and were allocated to a single group after fulfilling inclusion and exclusion criteria. Baseline data like age, gender, Hoehn&Yahr stage was noted. Subjects underwent dual task training 5 times a week, for 4 weeks. All the subjects were assessed using Timed Up and Go test, Fall Efficacy Scale and Parkinson's Disease Questionnaire-39. Results: The dual task training on mobility showed significant improvement in mobility, fear of fall and quality of life in post-test 1. Retention effect (post-test 2) also showed significant improvement but compared to post-test 1 (p<0.001), it has reduced (p<0.05). Conclusion: The result of present study shows significant retention effect of dual task training on mobility, fear of fall and quality of life. The results also show that regular training is required for the subjects to maintain the progress achieved. [ABSTRACT FROM AUTHOR]

Background: This randomized controlled study compared standard supervised physiotherapy (SPT) with a self-developed, home-based, enhanced knee flexion exercise program involving a low stool (KFEH) in patients who underwent total knee arthroplasty (TKA). Methods: Patients were recruited from July 2014 to December 2015 and randomly assigned to one of two groups: KFEH (n = 60) and SPT (n = 59). Outcomes (joint function) were evaluated according to the Knee Society Score (KSS), visual analog scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and range of motion (ROM) assessment at selected time points (preoperatively; 1 week; 1, 3, and 6 months; and 1 year after surgery). Results: Pain and functional improvement were observed in both groups. Non-inferiority of KFEH was evident 12 months postoperatively; however, patients in the KFEH group exhibited better ROM at 1 month (P < 0.01). Absolute WOMAC and KSS scores were slightly better in the KFEH group, although the difference was not statistically significant. There was no difference in VAS scores and complication rates between the two groups. Additionally, the home program would save patient time and decrease the economic burden associated with in-hospital SPT. Conclusion: Considering rehabilitation and economic efficiency as well as the COVID pandemic, a home-based enhanced knee flexion exercise program for TKA rehabilitation is recommended.

Background: Multiple sclerosis (MS) impairs muscular function and limits individuals' ability to perform everyday activities requiring mobility. People with MS frequently exhibit mobility problems (ie, slower walking speed, shorter strides). General exercise training (eg, resistance, aerobic) provides modest physiological and walking mobility benefits. However, researchers suggest tailoring of interventions to address mobility specifically. We conducted a phase 2a pre-post intervention development study (Obesity-Related Behavioral Intervention Trials [ORBIT] intervention development model) of mobility exercise plus cognitive behavioral counseling to improve function and social cognitions known to encourage exercise. Methods: The intervention was conducted twice per week for 8 weeks followed by 1 month of self-managed mobility exercise. Participants (N = 29; mean ± SD age = 52.24 ± 11.36 years, mean time since MS diagnosis ≥11 years) were assessed at baseline and after follow-up for mobility function, social cognitions, and intervention fidelity indicators. Results: Results indicated significant improvements in a variety of valid measures of mobility function (eg, 400-m walk), self-regulatory efficacy for mobility exercise and symptom control, and fidelity measures with small to medium effect sizes. Conclusions: Positive findings suggest that the intervention seems to merit testing as a randomized pilot study following the ORBIT model. [ABSTRACT FROM AUTHOR]

Study Objective: To find out the effectiveness of yoga based exercise therapy program on Balance, Mobility and Gait speed in institutional living older adults. Design: Pre and Post- test experimental design Setting: Daivadan old age home, Chethimattom, Kottayam, Kerala Subjects: 30 male older adults, they are divided into Group A and B with 15 subjects each Measurement: After measuring Balance, Mobility and Gait speed scores Group A was given their normal exercise along with Yoga which includes several Asanas and Pranayamas. Group B continue with their normal exercise and they had not undergone any yoga. The treatment duration was 6 days in a week for a total period of 4 weeks Result: The results showed that there was a significant result in Balance, Mobility and Gait speed scores for the older adults received Yoga based exercise therapy program Conclusion: The study's results show that Yoga based exercise therapy program when added to standard care improves Balance, Mobility and Gait speed in old aged adults and enhance fall preventions in comparison to conventional exercise alone [ABSTRACT FROM AUTHOR]

S14 Lupus erythematosus and sleep hygiene: A salutogenic perspective Jorge Manuel Molina Aguilar (jmolina@uca.edu.sv) Universidad Centroamericana José Simeón Cañas, El Salvador, San Salvador, Centroamérica B Background b Research on individuals with lupus erythematosus has a number of limitations: (a) lack of clear theoretical framework of the social mechanisms underlying the development of life skills needed for healthy living, (b) narrow focus centered on biomedical models and health medicalization, and (c) implicit and explicit health hierarchies, especially between social sciences and health sciences. B Results b Application of the salutogenic health model resulted in the following contributions: 1) identification of the mechanisms that underlie the daily lifestyle activities of people with lupus (understandability, manageability and significance), 2) recognition that sleep difficulties arise from the interaction between: physical pain, stressors related to health and financial conditions, as well as ability to understand the disease, uncertainty and fear about their social context, 3) alcohol use and self-medication habits as strategies to fall asleep, regardless of prior knowledge of the mental and physical health consequences. B Materials and methods b This cohort design study with two measurements surveyed 69 health sciences students enrolled in an older adult population study class of a public university of Mexico. B Conclusions b The implementation of health promotion programs that include multicomponent physical activity can represent a positive impact on the biopsychosocial health of elderly.
