The emergence of tele-exercise as a response to the impact of technology on physical activity has opened up new possibilities for promoting physical health. By integrating innovative technologies and open-source platforms, tele-exercise encourages people to stay active. In our latest analysis, we delved into the scientific literature surrounding the use of tele-exercise technologies in training healthy individuals. After conducting an extensive search on the PubMed database using the keywords "tele-exercise" and "physical activity" (from 2020 to 2023), we identified 44 clinical trials that were applicable to tele-exercise, but less than 10% of them were aimed at healthy individuals, precisely 9.09% (four out of forty-four studies analyzed). Our review highlights the potential of tele-exercise to help maintain physical fitness and psychological well-being, especially when traditional fitness facilities are not an option. We also underscore the importance of interoperability, standardization, and the incorporation of biomechanics, exercise physiology, and neuroscience into the development of tele-exercise platforms. Nevertheless, despite these promising benefits, research has shown that there is still a significant gap in the knowledge concerning the definition and evaluation of training parameters for healthy individuals. As a result, we call for further research to establish evidence-based practices for tele-exercise in the healthy population. [ABSTRACT FROM AUTHOR]

There is limited research on female football players, especially related to their physical and cognitive performance under different climactic conditions. We analyzed the impact of a hot environmental temperature on physical performance and anticipation in elite female football players during a fatigue‐inducing intermittent protocol. Elite female players (n = 21) performed the countermovement jump (CMJ) and responded to filmed sequences of offensive play under two distinct environmental temperatures (i.e., mild environment temperature‐ 20°C and 30% rh versus hot environment temperature‐ 38°C and 80% rh), interspersed by 1‐week interval. Linear mixed models were used. CMJ performance declined following the intermittent protocol on both temperature conditions (p < 0.05). Moreover, there were significant main effects for protocol on CMJ speed (m/s) (p = 0.001; ηp2 = 0.12), CMJ power (p = 0.002; ηp2 = 0.11), and CMJ Heightmax (p = 0.002; ηp2 = 0.12). After performing the intermittent protocol, exposure to a hot temperature caused a greater decline in anticipation accuracy (mild temperature = 64.41% vs. hot temperature = 53.44%; p < 0.001). Our study shows impaired performance in elite female football players following an intermittent protocol under hot compared with mild environmental conditions. We report decreased performance in both CMJ and anticipation performance under hotter conditions. The results reveal that exposure to hot temperatures had a negative effect on the accuracy of their anticipatory behaviors. We consider the implication of the work for research and training interventions. [ABSTRACT FROM AUTHOR]

Air Bike ergometers have recently appeared and become popular among fitness. These ergometers combine the use of upper or lower limbs while remaining seated. Its characteristic is that of a system of external load imposed through air resistance which increases with the cadence imposed on the equipment. The present study aimed to evaluate the reliability of the ramp test and standard leg-cycle ergometer to assess maximum oxygen uptake (VO2max). For this purpose, 18 physically active young men, aged between 19 and 29 years (mean ± standard deviation= 21.78± 2.44), performed three maximal incremental ramp tests in random order: one test on a cycle ergometer and two tests on an Air Bike arm- and leg- ergometer (test and re-test) with cardiorespiratory measurements throughout the tests. VO2max and maximum heart rate (HRmax) were significantly higher in the Air Bike compared with the cycle ergometer (53.06± 8.72 vs 47.38± 9.15 mL/min/kg), 181.93± 10.20 vs 176.07± 5.28 bpm, p< 0.001; 95%CI 3.41–7.95; ES= 0.30 and p= 0.01; 95%CI 1.44–10.29; ES= 0.34, respectively for VO2max and HRmax). There were no differences between the two ergometers in the maximum respiratory exchange ratio (RER) and test duration (1.21± 0.13 vs 1.21± 0.13, 598.06± 37.28 vs 612.22± 86.40 s, p= 0.9; IC95% –0.05 – –0.05; ES= 0 and p= 0.4; 95%CI –46.12–17.79; ES= –0.11, respectively for RER and test duration). Both VO2max and HRmax showed to be reliable when assessed with the Air Bike ergometer. The maximal test carried out on the Air Bike is a reliable ergometer to assess VO2max and probably enables a higher VO2max as compared with a standard leg-cycle ergometer., Introdução: Os ergômetros Air Bike surgiram recentemente e rapidamente ficaram populares no fitness. Estes ergômetros combinam o uso de membros superiores ou inferiores, mesmo quando está sentado. Tem como característica um sistema de carga externa imposta através da resistência do ar que aumenta com a cadência imposta. Objetivo: o objetivo do presente estudo foi investigar se um teste de rampa incremental no ergômetro Air Bike é uma ferramenta válida e confiável para avaliar o consumo máximo de oxigênio (VO2max). Métodos: Para isso, dezoito homens jovens fisicamente ativos, com idades entre 19 e 29 anos (média ± desvio padrão = 21,78 ± 2,44), realizaram três testes de rampa incremental máxima em ordem aleatória: um teste em cicloergômetro e dois testes na Air Bike (teste e reteste) com medidas cardiorrespiratórias ao longo dos testes. Resultados: O VO2máx e a frequência cardíaca máxima (FCmáx) foram significativamente maiores na Air Bike em relação ao cicloergômetro (53,06 ± 8,72 vs 47,38 ± 9,15 mL/min/kg), 181,93 ± 10,20 vs 176,07 ± 5,28 bpm, p

Chronic kidney disease is a rising health issue that affects millions of people worldwide. Early detection and characterization of this disease is essential for effective management and control. This disease is associated with several serious health risks, such as cardiovascular disease, increased risk of stroke, and end-stage renal disease, which can be effectively prevented by early detection and treatment. Medical scientists rely on machine learning algorithms to diagnose the disease accurately at its outset. Recently, adding value to healthcare is being accomplished through the integration of machine learning algorithms into mobile health solution. Considering this, this paper proposes a predictive model of three machine learning classifiers, including Support Vector Machine, Decision Tree, and Multilayer Perceptron for chronic kidney disease prediction. The performance of the model was assessed using confusion matrix and executed in popular machine learning software tools such as WEKA and Rapid Minor. The study found that support vector machine yielded the highest accuracy rate of 98% in predicting chronic kidney disease in WEKA among other standard classifiers by using 10-fold cross validation. In addition, the proposed prediction model has been compared with existing models in terms of accuracy, sensitivity, and specificity. The experimental results indicate that the proposed predictive model shows promising results. These findings could integrate with the development of mobile health solution and other innovative approaches to prevent and treat this debilitating condition. [ABSTRACT FROM AUTHOR]

This descriptive article explores the use of smart devices for health and wellness in the context of telehealth, highlighting rapidly evolving technologies such as the Internet of Things (IoT) and Artificial Intelligence (AI). Key innovations, benefits, challenges, and opportunities related to the adoption of these technologies are outlined. The article provides a descriptive and accessible approach to understanding the evolution and impact of smart devices in the tele-exercise reality. Nowadays, technological advances provide solutions that were unthinkable just a few years ago. The habits of the general population have also changed over the past few years. Hence, there is a need to investigate this issue and draw the attention of the scientific community to this topic by describing the benefits and challenges associated with each topic. If individuals no longer go to exercise, the exercise must go to their homes instead. [ABSTRACT FROM AUTHOR]

The present study aimed to analyze swimmers' in-water kinetic and kinematic behaviors according to different swimming performance tiers within the same age group. An amount of 53 highly trained swimmers (girls and boys: 12.40 ± 0.74 years) were split up into 3 tiers based on their personal best performance (i.e., speed) in the 50 m freestyle event (short-course): lower-tier (1.25 ± 0.08 m·s−1); mid-tier (1.45 ± 0.04 m·s−1); and top-tier (1.60 ± 0.04 m·s−1). The in-water mean peak force was measured during a maximum bout of 25 m front crawl using a differential pressure sensors system (Aquanex system, Swimming Technology Research, Richmond, VA, USA) and defined as a kinetic variable, while speed, stroke rate, stroke length, and stroke index were retrieved and considered as kinematic measures. The top-tier swimmers were taller with a longer arm span and hand surface areas than the low-tier, but similar to the mid-tier. While the mean peak force, speed and efficiency differed among tiers, the stroke rate and stroke length showed mixed findings. Coaches should be aware that young swimmers belonging to the same age group may deliver different performance outcomes due to different kinetic and kinematic behaviors. [ABSTRACT FROM AUTHOR]

Background: This study aims to show the clinical outcomes of implants supporting mandibular overdentures in edentulous patients. Methods: Mandibular edentulous patients were diagnosed with an oral examination, panoramic radiograph, and diagnostic casts for intermaxillary relations and treated with overdentures over two implants. After two-stage surgery, implants were early loaded with an overdenture at 6 weeks. Results: Fifty-four patients (28 females and 24 males) were treated with 108 implants. Thirty-two patients (59.2%) had a previous history of periodontitis. Twenty-three patients (46%) were smokers. Forty patients (74.1%) suffered from systemic diseases (i.e., diabetes, cardiovascular diseases). The clinical follow-up of the study was 147.8 ± 10.4 months. The clinical outcomes showed a global success of 94.5% of implants. Fifty-four overdentures were placed in the patients over the implants. The mean marginal bone loss was 1.12 ± 0.34 mm. Nineteen patients (35.2%) showed some kind of mechanical prosthodontic complication. Sixteen implants (14.8%) were associated with peri-implantitis. Conclusions: Based on the clinical results obtained, we can determine that the treatment of elderly edentulous patients with mandibular overdentures through the early loading of two placed implants is a successful implant protocol.

Code linters are tools for detecting improper uses of programming constructs and violations of style issues. Despite that professional linters are available for numerous languages, they are not targeted to introductory programming, given their prescriptive nature that does not take into consideration a didactic viewpoint of learning programming fundamentals. We present Sprinter, a didactic code linter for structured programming supporting Java whose novelty aspects are twofold: (a) providing formative feedback on code with comprehensive explanatory messages (rather then prescriptive); (b) capability of detecting some control-flow issues to a deeper extent than professional linters. We review Sprinter features against popular tools, namely IntelliJ IDEA and Sonarlint., OASIcs, Vol. 102, Third International Computer Programming Education Conference (ICPEC 2022), pages 2:1-2:8

The purpose of this study was to investigate the acute effects of multi-joint resistance exercises (MJRE) with blood flow restriction on hormonal responses. Ten men participated in the study and underwent two experimental protocols in random order: four sets (30, 15, 15, and 15 reps, respectively) of MJRE (half squat and horizontal chest press) were performed with 20% of 1RM and a rest time between sets of 30 s, combined with intermittent blood flow restriction (LI + BFR protocol); and four sets (8, 8, 8, 20 reps, respectively) of the same MJRE performed with 75% of 1RM load (HI protocol), with a 90 s rest between the first three sets and 30 s between the third to the fourth set. Blood samples were collected before (PRE), immediately after (POST), and 15 min after the performance of MJRE (POST15). A time effect was observed for growth hormone (GH) and insulin-like-growth-factor-1-binding-protein-3 (IGFPB-3), but no protocol effects or interactions between protocol and times were observed (p > 0.05). There was no effect of either protocol or time (p > 0.05) on total testosterone, free testosterone, or cortisol concentrations. However, significant (p < 0.05) increases were observed in the GH serum concentrations of 2072.73% and 2278.5%, HI, and LI + BFR protocols, respectively, from the PRE to POST15 test. In addition, there was an increase of 15.30% and 13.29% in the IGFPB-3 concentrations (p < 0.05) from PRE to POST0 times for HI and LI + BFR protocols, respectively. Furthermore, there was a decrease of −6.17% and −11.54%, p = 0.00, between the times POST0 to POST15 in the IGFPB-3 for the HI and LI + BFR protocols, respectively. It is concluded that multi-joint resistance exercises combined with intermittent blood flow restriction seemed to promote acute hormonal responses in a manner similar to traditional exercise with high loads. Future studies may investigate whether chronic use of LI + BFR with MJRE may promote muscle hypertrophy. [ABSTRACT FROM AUTHOR]

The aim of this study was to analyze the agreement of the active drag coefficient measured through drag and propulsion methods. The sample was composed of 18 swimmers (nine boys: 15.9 ± 0.9 years; nine girls: 15.3 ± 1.2 years) recruited from a national swimming team. The velocity perturbation method was used as the drag measurement system and the Aquanex system as the propulsion system. For both sexes combined, the frontal surface area was 0.1128 ± 0.016 m², swim velocity 1.54 ± 0.13 m⋅s
-1 , active drag 62.81 ± 11.37 N, propulsion 68.81 ± 12.41 N. The level of the active drag coefficient agreement was calculated based on the mean values comparison, simple linear regression, and Bland Altman plots. The mean data comparison revealed non-significant differences (p > 0.05) between methods to measure the active drag coefficient. Both the linear regression (R² = 0.82, p < 0.001) and Bland Altman plots revealed a very high agreement. The active drag coefficient should be the main outcome used in the interpretation of the swimmers' hydrodynamic profile, because it is less sensitive to swimming velocity. Coaches and researchers should be aware that the active drag coefficient can also be calculated based on propulsion methods and not just based on drag methods. Thus, the swimming community can now use different equipment to measure the hydrodynamics of their swimmers. [ABSTRACT FROM AUTHOR]- Published

Saber nadar não é uma aptidão natural (Langerdorfer, 2014). Trata-se inequivocamente de uma competência adquirida que permite ao sujeito realizar atos motores intencionais para se propulsionar através da água. Por essa razão a aplicação do termo “competência aquática” não é inócua, dado que conceptualmente reflete um estado de prontidão, que se revela pela autonomia, confiança e satisfação do sujeito no meio aquático. É, portanto, um pressuposto biocomportamental que serve de base para a posterior aprendizagem de outras habilidades aquáticas mais complexas e especializadas, entre as quais o nado clássico das quatro técnicas se resume apenas a uma parcela. Deste modo, a competência aquática deve ser considerada enquanto sistema dinâmico, complexo e dependente das relações que o sujeito estabelece com o contexto aquático envolvente. Isto terá importantes implicações no domínio da capacidade de percecionar riscos e perigos, na prevenção do afogamento – nadar no mar, no rio, numa piscina ou com roupa atribuem condicionalismos diferentes, e por inerência requerem níveis de proficiência motora aquática distintos. Esta nota deflecte essa necessidade – reconhecer a importância da competência aquática em particular na população infantil Portuguesa. A justificativa inicia-se pelo reconhecimento da importância da experimentação de vivências, ação dos estímulos psico-motores durante a infância, salientando-se a importância da prática da natação, evocando: o seu “valor educativo”, enquanto exercício físico harmonioso, que conduz a benefícios significativos no desenvolvimento social, mental, emocional e motor da criança; o seu “valor no bem-estar e na saúde” pela importância em formar crianças fisicamente ativas, o que atribui uma menor probabilidade de ser tornarem cidadãos sedentários na vida adulta; o seu “valor social”, dado que a massificação da competência aquática constitui-se como uma medida direta para a diminuição do risco de afogamento, em particular junto das crianças, enquanto grupo etário de maior risco., Motricidade, Vol 15 No 1 (2019): Motricidade, Volume 15, n.º 1

For this purpose, 18 physically active young men, aged between 19 and 29 years (mean ± standard deviation= 21.78 ± 2.44), performed three maximal incremental ramp tests in random order: one test on a cycle ergometer and two tests on an Air Bike arm- and leg- ergometer (test and re-test) with cardiorespiratory measurements throughout the tests. VO2 max and maximum heart rate (HRmax) were significantly higher in the Air Bike compared with the cycle ergometer (53.06 ± 8.72 vs 47.38 ± 9.15 mL/min/kg), 181.93 ± 10.20 vs 176.07 ± 5.28 bpm, p< 0.001; 95%CI 3.41-7.95; ES= 0.30 and p= 0.01; 95%CI 1.44-10.29; ES= 0.34, respectively for VO2 max and HRmax). There were no differences between the two ergometers in the maximum respiratory exchange ratio (RER) and test duration (1.21 ± 0.13 vs 1.21 ± 0.13, 598.06 ± 37.28 vs 612.22 ± 86.40 s, p= 0.9; IC95% -0.05 - -0.05; ES= 0 and p= 0.4; 95%CI -46.12-17.79; ES= -0.11, respectively for RER and test duration). Both VO2 max and HRmax showed to be reliable when assessed with the Air Bike ergometer. The maximal test carried out on the Air Bike is a reliable ergometer to assess VO2 max and probably enables a higher VO2 max as compared with a standard leg-cycle ergometer.

Background: Paralympic powerlifting (PP) training is typically intense and causes fatigue and alterations in the immune system. Objective: To analyze whether IBU would affect performance and the immune system after training in PP. Methodology: 10 athletes at the national level (NL) and 10 at the regional level (RL) participated in the study, where force and blood indicators were evaluated after training. The study took place over three weeks: (1) familiarization and (2 and 3) comparison between recovery methods, with ibuprofen or placebo (IBU vs. PLA), 800 mg. In the evaluation of the force, the peak torque (PT), fatigue index (FI), and blood immune system biomarkers were analyzed. The training consisted of five sets of five repetitions with 80% of one maximum repetition (5 × 5, 80% 1RM) on the bench press. Results: The PT at the national level using IBU was higher than with PLA (p = 0.007, η2p = 0.347), and the FI in the NL was lower with IBU than with PLA (p = 0.002, η2p = 0.635), and when comparing the use of IBU, the NL showed less fatigue than the regional level (p = 0.004, η2p = 0.414). Leukocytes, with the use of IBU in the NL group, were greater than in the RL (p = 0.001, η2p = 0.329). Neutrophils, in the NL with IBU, were greater than in the RL with IBU and PLA (p = 0.025, η2p = 0.444). Lymphocytes, in NL with IBU were lower than in RL with IBU and PLA (p = 0.001, η2p = 0.491). Monocytes, in the NL with IBU and PLA, were lower than in the RL with IBU (p = 0.049, η2p = 0.344). For hemoglobin, hematocrit, and erythrocyte, the NL with IBU and PLA were higher than the RL with IBU and PLA (p < 0.05). Ammonia, with the use of IBU in the NL, obtained values higher than in the RL (p = 0.007), and with the use of PLA, the NL was higher than the RL (p = 0.038, η2p = 0.570). Conclusion: The training level tends to influence the immune system and, combined with the use of the IBU, it tends to improve recovery and the immune system. [ABSTRACT FROM AUTHOR]

Drowning is responsible for about 372000 deaths per year around the world (OMS, 2014). Nowadays, Swimming Instruction is considered a relevant preventive measure for drowning. However, the act of swimming by itself does not ensure the victim full protection; thereby, this study embraces the concept of Water Competency because it includes swimming competencies, awareness, attitude and risk management. Based on a series of studies called "Can you Swim? Survey" (Moran et al., 2012), it was established an evaluation protocol on Perceived Water Competency (PWC), Real Water Competency (RWC) and Risk Management (RM) adapted to the Portuguese reality, focused especially in the Azorean educational context. Aside from these competencies evaluation, the protocol also describes the environmental and sociocultural influences and the Physical Education subject and Sports on the development of water competencies. This work aims to bridge the gap of a standard evaluation methodology of Water Competency (WC). Adding a set of tasks and an effective review of the obtained results, the present methodology allows the classification of groups of students into approved/not approved as an essential precondition of the activities/categories' safe execution in the nautical area. It also presents a dissemination of the tools constructed and established partnership's methodology. A pilot application was carried out in a group of students (n = 115) with an average age of de 14.58 years for both genders. This test sample belongs to six geographically balanced schools in São Miguel Island -- Azores. The obtained results suggest that participants in this study were unable to accurately predict their actual swimming and survival skills, and no significant differences were evident in perceived or actual competency by gender. It was proven that regular informal exposure affects some of the tested competencies. However, the Physical Education classes swimming lessons variable was responsible for the bigger differences. In the end, we checked that formal Competitive Swimming lessons are the variable that shows a bigger influence in the PWC, in particular on the perceived activities of "maximum distance swam in 15 minutes" (Mann-Whitney U = 739, p = 0.000), "100 m backstroke" (Mann-Whitney U = 699, p = 0.000) and "dive entry headfirst" (Mann-Whitney U = 963, p = 0.010); in RM on the: "caught in a rip current at beach" (Mann-Whitney U = 972.5, p = 0.029) and "chased toy into the deep end of a swimming pool" (Mann-Whitney U = 957, p = 0.022); and in RWC on the activities: "maximum distance swam in 15 minutes" (Mann-Whitney U = 777, p = 0.000), "underwater swimming" (Mann-Whitney U = 963.5, p = 0.023), "100 m backstroke" (Mann-Whitney U = 712, p = 0.000) and "2 m surface dive" (Mann- Whitney U = 921.5, p = 0.012). Thereby, when having a major exposure combined with organised water safety or swimming lessons, the RWC increases. This work highlights the importance of proper conditions to maximise exposure and aquatic education amongst young people, leading to the prevention of drowning. [ABSTRACT FROM AUTHOR]

PLICA syndrome ,PATELLOFEMORAL joint ,KNEE ,RUNNING - Abstract
Dynamic knee valgus (DKV) is a frontal plane knee kinematic alteration that has been associated with patellofemoral pain (PFP) in female runners. DKV is commonly assessed in clinical practice by measuring frontal plane knee projection angle (FPPA) during squat tests. However, it remains unclear whether the DKV observed in these tests is similar to or correlates with that observed during running in female runners. The aims of this cross-sectional study were to correlate and compare DKV, by measuring FPPA values, in a lateral step-down (LSD) squat test and running in female runners with and without PFP. A two-dimensional (2D) video analysis of the LSD test and running was carried out for 21 asymptomatic female runners and 17 PFP female runners in order to determine FPPA values. A Pearson correlation test and a factorial ANOVA with Bonferroni post hoc correction were used for statistical analysis. The FPPAs recorded in the LSD test were significantly higher than those recorded during running in the asymptomatic (16.32° ± 5.38 vs. 4.02° ± 3.26, p < 0.01) and PFP groups (17.54° ± 7.25 vs. 4.64° ± 3.62, p < 0.01). No significant differences were found in FPPA values between asymptomatic and PFP runners during the LSD test (16.32° ± 5.38 vs. 17.54° ± 7.25, p = 0.55) and running (4.02° ± 3.26 vs. 4.64° ± 3.62, p = 0.58). There was a small (r < 0.3) and non-significant (p > 0.05) correlation in FPPAs between the LSD test and running in both groups. According to our results, DKV was not similar during the LSD test and running, and there was no significant correlation in FPPA values between the LSD test and running in both groups. Therefore, clinicians and therapists should be aware of these findings when using the LSD test in clinical practice to evaluate DKV in female runners with or without PFP. [ABSTRACT FROM AUTHOR]

Current patterns of preventive antibiotic prescribing are encouraging the spread of antimicrobial resistance. Recently, the Spanish Society of Implants (SEI) developed the first clinical practice guidelines published to date, providing clear guidelines on how to prescribe responsible and informed preventive antibiotic therapy (PAT) based on the available scientific evidence on dental implant treatments (DIs). The present document aims to summarise and disseminate the recommendations established by this expert panel. These were based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were analysed using the Scottish Intercollegiate Guidelines Network (SIGN) checklist templates and ranked according to their level of evidence. They were then assigned a level of recommendation using the Grading of Recommendations, Assessment, Development and Evaluation system (GRADE). Guidelines were established on the type of PAT, antibiotic and dosage of administration in the placement of DIs without anatomical constraints, in bone augmentation with the placement of DIs in one or two stages, placement of immediate DIs, sinus elevations, implant prosthetic phase, as well as recommendations in patients allergic to penicillin. Therefore, the PAT must be adapted to the type of implant procedure to be performed. [ABSTRACT FROM AUTHOR]

The present study aimed to assess the precision of oxygen uptake with heart rate regression during treadmill running in highly trained runners. Twenty national and international level male runners were divided into two equal groups. Group A was formed of 10 sprinters (31.5± 4.7 years, height 1.74± 0.04 m and mass 61.8± 5.2 kg), and group B comprised 10 endurance runners (25.7± 4.5 years, height 1.77± 0.08 m and mass 71.2± 5.8 kg). Each participant performed six min bouts at a constant velocity on a level treadmill, with each bout at an increased running velocity. The starting velocity was 3.33 m·s-1, with a 0.56 m·s-1 increase in each subsequent bout. VO2 and HR were measured during all runs. Mean peak VO2 and mean peak HR for Group A were, respectively, 71.7± 7.0 mL·kg-1·min-1 and 179.8± 12.7 beats·min-1, while for Group B were 67.3± 4.9 mL·kg- 1·min-1 and 198.2± 9.8 beats·min-1. The linearity of the regressions between VO2 and HR in both groups was very high (R2= 0.97 and R2 =0.76) with small standard errors of regression. Despite a stronger correlation in endurance-trained athletes, the results of the present study indicate that it is possible to use HR as an indicator of exercise intensity in individuals trained in both speed and longer distances.

One of the key factors in the swimming teaching-learning process seems to be the variation of water’s depth.However, there are almost no studies about this topic and the existing ones usually follow a basic approach and with no control of the educational program used. It was our purpose to determine the effect of deep versus shallow water differences on developing pre-schoolers’ aquatic skills after 6 months of practice. Twenty-one Portuguese school-aged children of both genders (4.70 ± 0.51 yrs.), inexperienced in aquatic programs, participated in this study. The children were divided into two groups performing a similar aquatic program but in a different water depth: shallow water (n=10) and deep water (n=11). Each participant was evaluated twice for their aquatic readiness using an observation check list of 17 aquatic motor skills: during the first session (T0) and after six months of practice (two sessions per week with a total of 48 sessions) (T1). The aquatic proficiency on each skill was compared between the groups and a stepwise discriminant analysis was conducted to predict the conditions with higher or lower aquatic competence. Results suggested that swimming practice contributed positively to improvements on several basic aquatic skills, in both groups. The results showed that shallow water group managed to acquire a higher degree of aquatic competence particularly in five basic aquatic skills (p< .05): breath control combined with face immersion and eye opening; horizontal buoyancy; body position at ventral gliding; body position at dorsal gliding; leg kick with breath control at ventral body position, without any flutter device. The discriminant function revealed a significant association between both groups and four included factors (aquatic skills) (p< .001), accounting for 88% between group variability. The body position at ventral gliding was the main relevant predictor (r=0.535). Shallow water swimming lessons generated greater aquatic competence in preschool children after a period of 6 months of practice., Motricidade, Vol 14 No 1 (2018): Motricidade

The aim of this study was to analyze the progression and stability in the performance of world-ranked swimmers from 2015 to 2020, and the impairment induced by the COVID-19 lockdown. An observational retrospective design over five consecutive competitive seasons was selected. FINA´s male Top-50 who were qualified for the Tokyo Olympic Games were considered in freestyle, backstroke, backstroke, and butterfly events. A total of 515 male swimmers and 2060 season-best performances were analyzed. All data was retrieved from two open-access and public websites (Swimrankings and Swimcloud). Repeated measures ANOVA followed by the Bonferroni post-hoc test was performed to analyze the variation between seasons. Stabilization in performance was assessed using spearman correlation coefficients. A significant improvement in performance ≈0.5-2.5% was found in most of the strokes and race distances until the 2018-2019 season. The 2020 lockdown impaired the performance by 1-2%. Moderate to high associations were found in the 2017-2018 season when considering the 2019-2020 performance. The breaststroke was the only stroke with a moderate-high stability (r > 0.40) in all race distances considering the overall time period. It can be concluded that world-ranked swimmers' performance was impaired by 1-2% due to the COVID-19 lockdown, returning to levels that were reached two years earlier. [ABSTRACT FROM AUTHOR]

Paralympic Powerlifting is a sport in which the strength of the upper limbs is assessed through bench press performance in an adapted specific bench. It is therefore essential to optimize training methods to maximize this performance. The aim of the present study was to compare force production and muscle activation involved in partial vs. full range of motion (ROM) training in Paralympic Powerlifting. Twelve male athletes of elite national level in Paralympic Powerlifting participated in the study (28.60 ± 7.60 years of age, 71.80 ± 17.90 kg of body mass). The athletes performed five sets of 5RM (repetition maximum), either with 90% of 1RM in full ROM or with a load of 130% 1RM in partial ROM. All subjects underwent both exercise conditions in consecutive weeks. Order assignment in the first week was random and counterbalanced. Fatigue index (FI), Maximum Isometric Force (MIF), Time to MIF (Time) and rate of force development (RFD) were determined by a force sensor. Muscle thickness was obtained using ultrasound images. All measures were taken pre- and post-training. Additionally, electromyographic signal (EMG) was evaluated in the last set of each exercise condition. Post-exercise fatigue was higher with full ROM as well as loss of MIF. Full ROM also induced greater. EMG showed greater activation of the Clavicular portion and Sternal portion of pectoralis major muscle and lower in the anterior portion of deltoid muscle when full ROM was performed. Muscle thickness of the pectoralis major muscle increased post-exercise. We concluded that training with partial ROM enables higher workloads with lower loss of muscle function.

The objective of this study was to analyze the effects of the reduction of ankle mobility on the jumping performance of young soccer athletes, through a validated jump platform valued and test. Twenty-one soccer players (16.19±0.60 years old, 67.26±5.94 kg weight, 173.81±8.15cm height, 11.29±5.37% estimated body fat, and 8.76±2.70 years of soccer practice) were evaluated and tested for vertical jump performance. Goniometry and Knee-to-Wall tests were adopted in order to evaluate movement and a jump platform was used to evaluate performance. The performance in Counter Movement Jump test correlated positively and significantly not only with right dorsiflexion test but also right Knee-to-Wall test (r = 0.576; p = 0.006, r = 0.513, p = 0.17, respectively). Right Knee-to-Wall is correlated with left Knee-to-Wall (r = 0,816 p = 0,001). Based on the presented data the vertical jump is impaired by ankles mobility deficit.

O excesso de peso é cada vez maior entre da população escolar jovem. Uma vez que não é evidente qual a atitude dos alunos com sobrepeso e obesidade face à participação em atividades físicas e sua relação com o desempenho escolar pretendemos identificar os factores de influência no contexto da EF escolar. Participaram neste estudo 490 alunos dos 3º ciclo e ensino secundário, divididos por sexo. Os valores de IMC foram ajustados para sexo e idade e criados três grupos: Magreza; peso normal; e excesso de peso. Os valores dos resultados escolares foram normalizadas para uma escala de 1 a 5 valores. A participação em atividades desportivas, regularidade de prática e percepção do sucesso escolar foi medida por questionário. Após análise exploratória dos dados foram realizados os testes do Qui-quadrado, ANOVA e correlação de Pearson. O eta quadrado parcial (η²) foi reportado como medida da magnitude do efeito das diferenças verificadas nas ANOVAs. Foi considerado o valor de α de 0.05. Os resultados mostraram que alunos com excesso de peso e magreza reportaram menores níveis de atividade física em relação a alunos normoponderais (4.20±1.73, 4.06±1.77, 4.61±1.73; p=0.044; η²=0.01, resp.). A maior parte dos alunos definiu o seu sucesso escolar através da aprovação/transição de ano a par de boas classificações, tendo este grupo obtido níveis superiores de prática (4.57±1.71, p=0.03) Verificaram-se efeitos significativos da variável níveis de IMC nas classificações médias finais e na disciplina de EF, em que os alunos normoponderais obtiveram melhores classificações do que os alunos com excesso de peso. Além disso, verificaram-se correlações significativas entre as classificações de Português e Matemática (r=0.80; p, Motricidade, Vol 11 No 3 (2015)

Background: The sticking region is considered an intervening factor in the performance of the bench press with high loads. Objective: To evaluate the strength indicators in the sticking point region in Powerlifting Paralympic athletes. Methods: Twelve Brazilian Powerlifting Paralympic athletes performed maximum isometric force (MIF), rate of force development (RFD), time at MIF, velocity, dynamic time in sticking, and surface electromyography in several distances from the bar to the chest. Results: For velocity, there was a difference between the pre-sticking and sticking region (1.98 ± 0.32 and 1.30 ± 0.43, p = 0.039) and dynamic time between the pre-sticking and the sticking region (0.40 ± 0.16 and 0.97 ± 0.37, p = 00.021). In static test for the MIF, differences were found between 5.0 cm and 15.0 cm (CI 95% 784; 1088; p = 0.010) and between 10.0 cm and 5.0 cm (CI 95% 527; 768; p < 0.001). Regarding the RFD, differences were found (CI 95% 938; 1240; p = 0.004) between 5.0 cm and 25.0 cm and between 10.0 cm and 25.0 cm (CI 95% 513; 732; p < 0.001). In relation to time, there were differences between 5.0 cm and 15.0 cm (CI 95% 0.330; 0.515; p < 0.001), 5.0 cm, and 25.0 cm (CI 95% 0.928; 1.345; p = 0.001), 10.0 cm and 15.0 cm (p < 0.05) and 15.0 cm and 25.0 cm (p < 0.05). No significant differences were observed between the muscles in electromyography, although the triceps showed the highest muscle activation values. Conclusions: The maximum isometric force, rate of force development, time, velocity, and dynamic time had lower values, especially in the initial and intermediate phases in the sticking region.

- Abstract
The purpose of this study was to verify the acute effects of different exercise orders and rest intervals between sets on young athletes performance. Sixteen young male football players (73.2 ± 4.8 kg, 177.5 ± 5.1 cm, BMI 23.2 ± 1.1, 19.8 ± 0.9 years) completed six experimental strength training (ST) sessions with different exercise order sequences (A and B) and rest interval lengths (1 min, 3 min, and self-selected).In Sequence A the exercises were: bench press (BP), back squat (BS), biceps curl (BC) and plantar flexion (PF); while Sequence B was performed in the opposite order (i.e. PF, BC, BS and BP).The total work volume (TWV) per exercise (sets x repetitions x load) and per training session (sum of the TWV of all exercises) were evaluated for all ST sessions. BC and PF exercises presented higher TWV in sequence B (p ≤ 0.05). Already, the exercises BP, BS and PF presented higher TWV with 3 min and self-selected rest intervals (p ≤ 0.05). The 3-min and self-selected rest intervals presented higher values of TWV per training session compared to the 1-min rest interval (p ≤ 0.05). The exercise order influenced certain exercises (BC and PF), which presented higher TWV when positioned at the beginning of a sequence. While the longer rest intervals (3 min and self-selected) resulted in higher TWV per exercise (BP, BS and PF) and per training session. These results suggest that self-selected rest interval can be implemented to increase training efficiency in young athletes. [ABSTRACT FROM AUTHOR]

Introduction: The literature has shown that a gap is identified regarding the acute effects of blood flow restriction training on aerobic variables. Objective: to analyze oxygen consumption (VO2) during and after two resistance training sessions: traditional high intensity and low intensity with blood flow restriction. Methods: After one-repetition maximum tests, eight male participants (25.7±3 years) completed the two experimental protocols, separated by 72 hours, in a randomized order: a) high intensity training at 80% of 1RM (HIRE) and b) low intensity training at 20% of 1RM combined with blood flow restriction (LIRE + BFR). Three sets of four exercises (bench press, squat, barbell bent-over row and deadlift) were performed. Oxygen consumption and excess post-exercise oxygen consumption were measured. Results: the data showed statistically significant differences between the traditional high intensity training and low intensity training with blood flow restriction, with higher values for traditional training sessions, except for the last five minutes of the excess post-exercise oxygen consumption. Oxygen consumption measured during training was higher (p = 0.001) for the HIRE (20.32 ± 1.46 mL·kg-1·min-1) compared to the LIRE + BFR (15.65 ± 1.14 mL·kg-1·min-1). Conclusion: Oxygen uptakes rates during and after the exercise sessions were higher for the high intensity training methodology. However, when taking into account the volume of training provided by both methods, these differences were attenuated. Level of Evidence III - Non-consecutive studies, or studies without consistently applied reference stand. RESUMO Introdução: Na literatura, é identificada uma lacuna em relação aos efeitos agudos do treino com restrição de fluxo sanguíneo sobre as variáveis aeróbicas. Objetivo: analisar o consumo de oxigênio (VO2) durante e após duas sessões de treino de força: tradicional de alta intensidade e baixa intensidade com restrição do fluxo sanguíneo. Métodos: Após os testes de repetição máxima, oito participantes do sexo masculino (25,7 ± 3 anos) completaram os dois protocolos experimentais, separados por 72 horas, em ordem aleatória: a) treino de alta intensidade, com 80% de 1RM (AI) e b) treino de baixa intensidade a 20% de 1RM combinado com restrição de fluxo sanguíneo (BI + RFS). Três séries de quatro exercícios (supino, agachamento, remada inclinada e levantamento terra) foram realizadas. O consumo de oxigênio e o consumo de oxigênio em excesso pós-exercício foram medidos. Resultados: foram observadas diferenças estatisticamente significativas entre o treino tradicional de alta intensidade e de baixa intensidade com restrição de fluxo sanguíneo, com valores mais altos para sessões de treinamento tradicionais, exceto nos últimos cinco minutos para a medida de consumo de oxigênio pós-exercício. O VO2 medido durante o treino foi maior (p = 0.001) para a sessão de AI (20.32 ± 1.46 mL·kg-1·min-1) comparada ao treino de BI + RFS (15.65 ± 1.14 mL·kg-1·min-1). Conclusão: O consumo de oxigênio durante e após as sessões de exercício foram maiores para a metodologia de treinamento de alta intensidade. Contudo, quando se considera o volume dos treinos, estas diferenças foram atenuadas. Nível de Evidência III - Estudos de pacientes não consecutivos; sem padrão de referência “ouro” aplicado uniformemente. RESUMEN Introducción: La literatura ha demostrado que se identifica una laguna con respecto a los efectos agudos del entrenamiento de restricción del flujo sanguíneo en las variables aeróbicas.

O 3º Congresso Internacional de Atividade Física, Nutrição e Saúde proporcionou discussão, reflexão e prática acerca das bases teórico-metodológicas dirigidas às intervenções na área de Atividade Física, Nutrição e Saúde. Reflexões sobre o processo de envelhecimento, bem como os aspetos do envelhecer com saúde e qualidade de vida foram abordados no evento. O envelhecimento é um fenômeno natural, universal, irreversível e não ocorre de forma simultânea e igualitária nos seres humanos. Envelhecer faz parte da vida e, visto a luz dos conhecimentos atuais, nada é possível para fazer alterar este processo. Atualmente, o envelhecimento constitui um dos temas de maior interesse da sociedade devido à transição epidemiológica que o mundo está apresentando. Diante disso, procurar respostas sobre quais são as mudanças que ocorrem nesse período, quais são as causas e as consequências são os desafios da ciência com o objetivo de retardar esse processo. Para melhor compreensão da relação entre envelhecimento e saúde, uma abordagem multidimensional deve ser considerada, levando em consideração os aspectos biológicos, físicos, psicológicos, econômicos e sociais. Além disso, a qualidade de vida passa a ser um aspecto importante por atender as demandas de saúde da sociedade. Tais discussões realizadas servirão para subsidiar uma análise crítica sobre a atuação dos profissionais da saúde, no Brasil e no Estado de Sergipe. É inadiável, portanto, que os acadêmicos e os professores de todas as áreas do conhecimento, conscientizem-se de que é necessário atualização e capacitação constante., Motricidade, Vol 13 (2017): CIAFIS – Congresso Internacional de Atividade Física, Nutrição e Saúde

As 2017 is ending evolution does not stop, and publishing systems are getting along with this evolvement, since the “publish or perish” dictum is nowadays a way of living among the academy. In this way, in this competitive context, one must keep the publication records updated and, most of all, visible, easy to find, or discoverable. Some questions arise related to this topic: how can publishers help to connect individuals with their contributions? How can publishers make the publishing process easier for the authors, editors, and reviewers? How can publishers improve discoverability?, Motricidade, Vol 13 No 4 (2017)

Abstract Background The association between physical activity and quality of life in stroke survivors has not been analyzed within a framework related to the human development index. This study aimed to identify differences in physical activity level and in the quality of life of stroke survivors in two cities differing in economic aspects of the human development index. Methods Two groups of subjects who had suffered a stroke at least a year prior to testing and showed hemiplegia or hemiparesis were studied: a group from Belo Horizonte (BH) with 48 people (51.5 ± 8.7 years) and one from Montes Claros (MC) with 29 subjects (55.4 ± 8.1 years). Subsequently, regardless of location, the groups were divided into Active and Insufficiently Active so their difference in terms of quality of life could be analyzed. Results There were no significant differences between BH and MCG when it came to four dimensions of physical health that were evaluated (physical functioning, physical aspect, pain and health status) or in the following four dimensions of mental health status (vitality, social aspect, emotional aspect and mental health). However, significantly higher mean values were found in Active when compared with Insufficiently Active individuals in various measures of physical health (physical functioning 56.2 ± 4.4 vs. 47.4 ± 6.9; physical aspect 66.5 ± 6.5 vs. 59.1 ± 6.7; pain 55.9 ± 6.2 vs. 47.7 ± 6.0; health status 67.2 ± 4.2 vs. 56.6 ± 7.8) (arbitrary units), and mental health (vitality 60.9 ± 6.8 vs. 54.1 ± 7.2; social aspect 60.4 ± 7.1 vs. 54.2 ± 7.4; emotional aspect 64.0 ± 5.5 vs. 58.1 ± 6.9; mental health status 66.2 ± 5.5 vs. 58.4 ± 7.5) (arbitrary units). Conclusions Despite the difference between the cities concerning HDI values, no significant differences in quality of life were found between BH and MCG. However, the Active group showed significantly better results, confirming the importance of active lifestyle to enhance quality of life in stroke survivors.

- Abstract
Objectives: A PubMed search has revealed a mere 4 papers published on bodyboard science, from 1995 to date. Moreover, modern wearable technology enabled to accurately assess heart rate during aquatic activities. The aims of the present study were to assess the reliability of a specific swimming-pool test for bodyboarders by measuring: i) aerobic response through heart rate; ii) anaerobic response through post-exercise peak blood lactate; and, iii) performance through mean velocity. Methods: Ten experienced bodyboarders (more than 4 years of training) volunteered for the study. The mean (±SD) age, body mass and height of the subjects were, respectively: 21,3±5,0 years, 64,7±8,6 kg, 1,72±5,9. The subjects performed a specific swimming-pool test. Testing was performed in a 50-m indoor heated swimming pool (26-27˚) and consisted of a 400-m individual time trial. The subjects paddled on a standard bodyboard using bodyboard swim fins. The test was repeated 72-h after. During both tests heart rate was continuously assessed with a Polar® device (RCX5 with H2 sensor). After testing ear-lobe capillary blood lactate was measured every minute until levelling-off with a Accutrend Plus® device. Reliability of repeated measurements was assessed with the coefficient of variation and significance level was set at p≤0.05. Results & Discussion: To the best of our knowledge this was the first study to assess the reliability of heart rate, blood lactate and velocity during a swimming-pool specific test for bodyboarders. Due to weather and tide constraints during natural bodyboarding it is difficult to have a reliable physiological response under field conditions. Hence, we propose herein a swimming-pool specific test based on a surfing specific swimming-pool test. In the present study, coefficients of variation were: 0,3% for peak heart rate, 1,8% for mean heart rate, 14,7% for post-exercise peak blood lactate and 1,7% for mean paddling velocity. Average measures with the two test were: 182,2±13,9 bpm peak heart rate, 170,3±15,4 bpm for mean heart rate, 9,7±2,6 mmol/L for post-exercise peak blood lactate and for 1,27±0,09 m/s mean paddling velocity. Conclusion: We conclude that the 400-m bodyboard paddling specific swimming-pool test seems to be a reliable measure of performance (mean velocity) and aerobic response (heart rate). Anaerobic response during this test (post-exercise peak blood lactate) presented a less reliable profile.
