Cardiorespiratory fitness and muscular fitness correlates in youth: A hierarchy of behavioral, contextual, and health-related outcomes.

OBJECTIVES: Despite the health importance of identifying correlates of physical fitness in youth, no investigation to date has explored the influence of behavioral, health-related, and contextual correlates simultaneously. We investigated the hierarchical relationship of multiple modifiable correlates favoring or diminishing cardiorespiratory and muscular fitness in youth. DESIGN: Cross-sectional investigation. METHODS: In a sample of 5174 children and adolescents, 31 correlates were hierarchized according to their impact on cardiorespiratory and muscular fitness assessed using the FITESCOLA® fitness battery. A Chi-squared Automatic Interaction Detection approach was employed and measures of correlation and association were used to investigate the relationship between physical fitness and correlates. RESULTS: In children, body mass index was the most relevant factor to discriminate between high and low cardiorespiratory and muscular fitness of the upper, middle, and lower body. While body mass index was more important than any other correlate to differentiate levels of upper and lower body muscular fitness during adolescence, specific characteristics of sports participation emerged as key factors to discriminate between high and low cardiorespiratory fitness and middle body muscular fitness. Other correlates, including the self-report of active recess time, active commuting to school, favorable neighborhood conditions, and limited time on screens and cellphones, were demonstrative of favorable physical fitness levels. CONCLUSIONS: Both body composition and sports-related characteristics emerged as the two most relevant factors of physical fitness in youth. Additional health benefits may be obtained from building supportive environments for sports and healthy exercise habits within the household and at different school education levels.

The Meaning of Physical Education Practice in Students with Attention-Deficit Hyperactivity Disorder (ADHD).

Purpose: This study seeks to describe the perspective of students with attention-deficit hyperactivity disorder (ADHD) and physical education (PE) teachers concerning physical activity practice in high school. Methods: A qualitative descriptive study based on an interpretative framework was conducted with secondary school students with ADHD, and their teachers of physical education. In-depth interviews and researchers' field notes were used to collect the data. Purposive sampling and inductive thematic analysis were applied. Results: Results show that ADHD is not experienced as limiting the practice of PA and PE by students, except in motor activities that require concentration such as tactical games. On the contrary, PA and PE helps them feel better. Teachers have not had to make extensive methodological modifications in their teaching styles with students with ADHD in relation to other situations or incidents. Conclusions: Students with ADHD do not seem to show significant difficulties in PE lessons or in the practice of extracurricular PA. PE teachers do not need to make significant adaptations with these students.

Training efficacy of robotic duct-to-mucosa pancreaticojejunostomy simulation using silicone models for surgical fellows.

Purpose: In the era of minimally invasive surgery (MIS), robotic pancreatoduodenectomy (PD) is actively performed, and clinical fellows need to thoroughly prepare for MIS-PD during the training process. Although pancreaticojejunostomy (PJ) is a difficult anastomosis that requires repeated practice, there are obstacles preventing its practice that concerns patient safety and limited time in the actual operating room. This study evaluated the efficacy of simulation-based training of robotic duct-to-mucosa PJ using pancreatic and intestinal silicone models using a scoring system. Methods: Three pancreatobiliary clinical fellows who had never performed a real robotic PJ participated in this study. Each trainee, who was well acquainted with master's video created by a senor surgeon, performed the robotic PJ procedures 9 times, and 3 independent pancreatobiliary surgeons assessed the videos and analyzed the scores using a blind method. Results: The mean robotic PJ times for the 3 trainees were 42.8 and 29.1 minutes for the first and 9th videos, respectively. The mean score was 13.8 (range, 6-17) for the first video and 17.7 (range, 15-19) for the 9th video. When comparing earlier and later attempts, the PJ time decreased significantly (2,201.67 seconds vs. 2,045.50 seconds, P = 0.007), whereas test scores increased significantly (total score 14.22 vs. 16.89, P = 0.011). Conclusion: This robotic education system will help pancreatobiliary trainees overcome the learning curves efficiently and quickly without raising ethical concerns associated with animal models or direct practice with human subjects. This will be of practical assistance to trainees preparing for MIS-PD.

The influence of physical education at school on the attention of students aged 15-16 years / El impacto de la educación física en la escuela en la atención de los estudiantes de 15 a 16 años / O impacto da educação física na escola na atenção de estudantes de 15 a 16 anos

ABSTRACT Objectives: the influence of physical activity in physical education lessons on the attention indicators of schoolchildren. Material and Methods: 141 students, aged 15-16, who studied in the 9th grade, took part in the experiment. The main research method was the "Trondyke Test", which determines the level of attention development of students. The test was used before and after the physical education lesson 1 time per month for 5 months. Results: students who did not engage in physical education in the lesson were not able to significantly improve their performance in the test, which indicates a possible adaptation to the test after its first performance before the lesson. Students who were engaged in physical exercises could significantly increase the test results. Conclusion: the results obtained determine the effectiveness of the influence of a physical education lesson at school on the indicators of students attention. This study will serve as an additional motivation for students to engage in physical culture, since the impact of physical exercises has a positive effect not only on the development of physical qualities, but also on the attention of schoolchildren. Level of Evidence III; Retrospective Comparative Study.

Evaluating Feasibility of a Secondary Stroke Prevention Program.

Healthy lifestyles including exercise and diet can reduce stroke risk, but stroke survivors often lack guidance to modify their lifestyles after hospital discharge. We evaluated the implementation of a new, secondary stroke prevention program involving supervised exercise, multidisciplinary education and coaching to address modifiable risk factors. The group-based program involved face-to-face and telehealth sessions. The primary outcomes were feasibility, examined via service information (referrals, uptake, participant demographics and costs), and participant acceptability (satisfaction and attendance). Secondary outcomes examined self-reported changes in lifestyle factors and pre-post scores on standardized clinical tests (e.g., waist circumference and 6-Minute Walk (6MWT)). We ran seven programs in 12 months, and 37 people participated. Attendance for education sessions was 79%, and 30/37 participants completed the full program. No adverse events occurred. Participant satisfaction was high for 'relevance' (100%), 'felt safe to exercise' (96%) and 'intend to continue' (96%). Most participants (88%) changed (on average) 2.5 lifestyle factors (diet, exercise, smoking and alcohol). Changes in clinical outcomes seemed promising, with some being statistically significant, e.g., 6MWT (MD 59 m, 95% CI 38 m to 80,159 m, p < 0.001) and waist circumference (MD -2.1 cm, 95%CI -3.9 cm to -1.4 cm, p < 0.001). The program was feasible to deliver, acceptable to participants and seemed beneficial for health. Access to similar programs may assist in secondary stroke prevention.

A Clinical Practice Guide to Enhance Physical Activity Participation for Children with Developmental Coordination Disorder in Canada.

Purpose: This clinical practice guide (CPG) aims to provide evidence-based recommendations for promoting and enhancing the participation and integration of children with developmental coordination disorder (DCD) into physical activities that take place in the home, school, community, or rehabilitation clinic contexts. Methods: A panel of key stakeholders relevant to these contexts (parents, instructors, rehabilitation professionals) developed evidence-based recommendations using a consensus methodology after reviewing results from a recent systematic review of relevant literature. The quality of the evidence on which the recommendations were based was evaluated (2011 Oxford Centre for Evidence-Based Medicine Levels of Evidence scale) as was the strength of the final CPG recommendations (American Society of Plastic Surgeons Grade Recommendation Scale). Results: Recommendations (n = 50; 36% supported by robust, empirically derived evidence) for the different stakeholder groups fell into three categories: 1) Choose an appropriate activity for your child, 2) Harmonize the activity with the child's interests and abilities, and 3) Help the child learn new movements prior to the activity. Conclusions: This comprehensive CPG provides concrete recommendations, based on the currently available evidence, that can be used by stakeholders to address the physical activity participation and integration needs of children with DCD in a variety of contexts.

Objectif: ces directives cliniques visent à fournir des recommandations basées sur les données probantes pour promouvoir et améliorer la participation et l'intégration des enfants ayant un trouble développemental de la coordination (TDC) à des activités physiques qui se déroulent à la maison, à l'école, dans la communauté ou dans des cliniques de réadaptation. Méthodologie: un groupe d'intervenants clés dans ces contextes (parents, entraineurs, professionnels de la réadaptation) a préparé des recommandations fondées sur des données probantes au moyen d'une méthodologie de consensus, après avoir révisé les résultats d'une récente analyse systématique de publications pertinentes. La qualité des données probantes sur laquelle reposent les recommandations a été évaluée (échelle de qualité des preuves de l'Oxford Centre for Evidence-Based Medicine de 2011) de même que les catégories des recommandations définitives tirées des directives (échelle des catégories de recommandations de l'American Society of Plastic Surgeons). Résultats: les recommandations (n = 50; 36 % soutenues par des données probantes empiriques vigoureuses) des divers groupes d'intervenants se déclinaient en trois catégories : 1) choisir une activité appropriée pour l'enfant, 2) harmoniser l'activité selon les intérêts et les capacités de l'enfant, 3) aider l'enfant à s'approprier de nouveaux mouvements pour aller vers l'activité. Conclusions: ces directives cliniques complètes fournissent des recommandations concrètes d'après les données probantes disponibles, que peuvent utiliser les intervenants pour aborder la participation à l'activité physique et les besoins d'intégration des enfants ayant un TDC dans divers contextes.

[Update of the recommendations of the Federal Falls Prevention Initiative-Identification and prevention of the risk of falling in older people living at home]. / Update der Empfehlungen der Bundesinitiative Sturzprävention ­ Identifizierung und Prävention des Sturzrisikos bei älteren zu Hause lebenden Menschen.

BACKGROUND: To reduce falls and their consequences, evidence-based and consensus-based recommendations are needed for risk stratification, screening, assessment, and fall prevention as well as treatment. In 2020, the Federal Falls Prevention Initiative (BIS) published recommendations for physical training for falls prevention as a group or individual intervention for older people living at home. In 2022, the world guidelines for falls prevention and management for older adults (WFG) were published. OBJECTIVE: To update the recommendations of the BIS. MATERIAL AND METHODS: The recommendations of the BIS were compared with those of the WFG and, if necessary, extended by methodological and subject-specific aspects. The following areas were considered: 1) screening and risk stratification, 2) interventions, 3) multifactorial assessment and interventions, and 4) specific target groups. RESULTS: The BIS recommendations are largely consistent with those of the WFG. The main reason for differences is the previous focus of the BIS recommendations on physical training. The multifactorial approach, which is described in detail by the WFG, has so far been mentioned in the recommendation paper on physical training in individual settings but not elaborated in detail. The BIS recommendations are supplemented or clarified in this respect. CONCLUSION: By updating the BIS recommendations, the establishment and promotion of fall prevention services for older people in Germany can be further advanced. The implementation can thus be carried out as consistently and scientifically proven as possible.

Interaction of Kinematic, Kinetic, and Energetic Predictors of Young Swimmers' Speed.

PURPOSE: The aim of this study was to assess the interaction of kinematic, kinetic, and energetic variables as speed predictors in adolescent swimmers in the front-crawl stroke. DESIGN: Ten boys (mean age [SD] = 16.4 [0.7] y) and 13 girls (mean age [SD] = 14.9 [0.9] y) were assessed. METHODS: The swimming performance indicator was a 25-m sprint. A set of kinematic, kinetic (hydrodynamic and propulsion), and energetic variables was established as a key predictor of swimming performance. Multilevel software was used to model the maximum swimming speed. RESULTS: The final model identified time (estimate = -0.008, P = .044), stroke frequency (estimate = 0.718, P < .001), active drag coefficient (estimate = -0.330, P = .004), lactate concentration (estimate = 0.019, P < .001), and critical speed (estimate = -0.150, P = .035) as significant predictors. Therefore, the interaction of kinematic, hydrodynamic, and energetic variables seems to be the main predictor of speed in adolescent swimmers. CONCLUSIONS: Coaches and practitioners should be aware that improvements in isolated variables may not translate into faster swimming speed. A multilevel evaluation may be required for a more effective assessment of the prediction of swimming speed based on several key variables rather than a single analysis.

Weekly cumulative extracurricular core training time predicts cadet physical performance: A descriptive epidemiological study.

Background: Core training can enhance athletic performance by enhancing core strength and stability. To achieve this outcome, however, a tailored training program is required; the normal military training curriculum is inadequate. The connection between cumulative weekly extracurricular training time, cumulative weekly extracurricular core training time and cadet performance is unknown. Methods: The association between cumulative weekly extracurricular training time, cumulative weekly extracurricular core training time and performance has been discovered using a descriptive epidemiological study methodology. Questionnaires were used to collect information on personal characteristics and weekly cumulative extracurricular (core) training time, as well as the results of the Chinese Army Physical Fitness Test (C-APFT), which included 100-m dash, 5000-m run, 3000-m armed training run, 400-m steeplechase, 800 m breaststroke, horizontal bar pull-ups, 2-min sit-ups, 2-min push-ups, and hand grenade throwing. This study recruited two hundred and twenty male cadets (aged 18 to 23 years, 19.68 ± 0.91) from a military medical university. Results: (a) The correlation between cumulative weekly extracurricular training time and C-APFT score is significant. The 100-m dash, 5000-m run, 3000-m armed training run, 400-m steeplechase, and 2-min push-ups performed the best when participants exercised for 5 to 10 h per week. (b) The number of cadets scoring good or excellent on the C-APFT improves with cumulative weekly extracurricular core training time. The recommended amount of core training for cadets per week is 120 min. (c) The average cumulative weekly extracurricular core training time was a effective predictor of performance on the 400-m steeplechase (R2 = 0.470, F = 10.641, P＜0.01), horizontal bar pull-ups (R2 = 0.238, F = 68.191, P＜0.01), 2-min sit-ups (R2 = 0.280, F = 84.710, P＜0.01), 100-m run (R2 = 0.031, F = 6.920, P＜0.01), 3000-m armed training run (R2 = 0.025, F = 5.603, P＜0.05), 2-min push-ups (R2 = 0.019, F = 4.295, P＜0.05), and hand grenade tossing (R2 = 0.025, F = 5.603, P＜0.05). Conclusions: Active participation in extracurricular core training can improve cadets' C-APFT scores. An average cumulative weekly extracurricular training duration of 5-10 h showed the most progress, and more than 120 min per week was ideal for extracurricular core training. The amount of extracurricular time spent on core training exercises each week can be used as a predictor of the C-APFT.

Análise do Efeito da Idade Relativa e do ano constituinte nas categorias de base do atletismo / Análisis del efecto de la edad relativa y el año constitutivo en las categorías básicas de atletismo / Analysis of the effect of relative age and constituent year on basic athletics categories

El presente estudio buscó analizar el Efecto de la Edad Relativa y el año constituyente en las categorías básicas del atletismo. Se decidió realizar un análisis del ranking general CBAt, tomando como muestra los datos de 2017. El enfoque de análisis consistió en un enfoque cuantitativo y cualitativo. La muestra estuvo compuesta por un total de 3.909 deportistas, hombres y mujeres, nacidos en los siguientes años: 1996 (n = 268); 1997 (n = 680); 1998 (n = 630); 1999 (n = 910); 2000 (n = 572); 2001 (n = 612); 2002 (n = 204); y 2003 (n = 33). Además, se entrevistó a seis entrenadores brasileños en la modalidad de atletismo para contribuir a las discusiones. Se puede observar que existe una tendencia a que el ranking deportivo de las categorías del base tenga una mayor sobrerrepresentación de los deportistas nacidos en los primeros meses del año, en relación a los nacidos en los últimos meses. Por otro lado, otro tema observado es que el año constitutivo de las categorías analizadas (16, 18 y 20 años) no tiene la mayoría de los resultados. Por tanto, son cuestiones que deben ser tenidas en cuenta por las personas que trabajan en el proceso de formación deportiva. (AU)

The present study sought to analyze the Effect of Relative Age and the constituent year in the basic categories of athletics. It was decided to carry out an analysis of the general CBAt ranking, taking the 2017 data as a sample. The analysis approach consisted of a quantitative and qualitative approach. The sample included a total of 3,909 athletes, male and female, born in the following years: 1996 (n = 268); 1997 (n = 680); 1998 (n = 630); 1999 (n = 910); 2000 (n = 572); 2001 (n = 612); 2002 (n= 204); and 2003(n = 33). In addition, six Brazilian coaches in the athletics modality were interviewed in order to contribute to the discussions. It is noticed that there was a tendency for the sports ranking of the basic categories to have agreater representation of athletes born in the first months of the year, in relation to those born in the final months. On the other hand, another issue observed is that the constituent year of the analyzed categories (16, 18 and 20 years) does not have the majorityof the results. Thus, these are issues that need to be taken into account by the people who work in the sports training process. (AU)

Optou-se em fazer uma análise do ranking geral da CBAt, tendo como amostra os dados de 2017. A abordagem de análise consistiu em uma abordagem quanti-qualitativa. Fizeram parte da amostra um total de 3.909 atletas, dos sexos masculino e feminino, nascidos nos seguintes anos: 1996 (n=268); 1997 (n=680); 1998 (n=630); 1999 (n=910); 2000 (n=572); 2001 (n=612); 2002 (n=204); e 2003(n=33). Além disto, seis técnicos brasileiros da modalidade de atletismo foram entrevistados com o intuito de contribuir para as discussões. Percebe-se que houve uma tendência de o ranking esportivo das categorias de base ter uma maior representação de atletas nascidos nos primeiros meses do ano, em relação aos nascidos nos meses finais. Por outro lado, outra questão observada, é que o ano constituinte das categorias analisadas (16, 18 e 20 anos) não possui a maioria dos resultados. Deste modo, essas são questões que precisam ser levadas em consideração pelas pessoasque atuam no processo de formação esportiva. (AU)

Have States Reduced Obesity by Legislating More Physical Activity in Elementary School?

Policy Points Between 1998 and 2016, 24 states and the District of Columbia passed laws meant to increase the time that children spent in physical education (PE) or other school-based physical activity (PA). Schools largely disregarded changes to PE/PA laws, which did not increase the time that children spent in PE or recess and did not reduce body mass index, overweight, or obesity. Closer oversight of schools would be needed to improve compliance with state PE and PA laws. Yet, even with better compliance, we estimate that PE and PA policies would be inadequate to reverse the obesity epidemic. Policies should also address consumption, both inside and outside of school. CONTEXT: To control childhood obesity, leading medical organizations have recommended increasing the time that children spend in physical education (PE) and other school-based physical activity (PA). Yet, it is unknown how many states have passed laws that codify these recommendations, and it is unknown what effect changing state laws has had on obesity or the time that children actually spent in PE and PA. METHODS: We joined state laws to national samples of 13,920 children from two different cohorts of elementary students. One cohort attended kindergarten in 1998; the other attended kindergarten in 2010; both cohorts were followed from kindergarten through fifth grade. We estimated the effects of changes to state laws in a regression with state and year fixed effects. FINDINGS: Twenty-four states and the District of Columbia increased the time that children were recommended or required to spend in PE or PA. These changes in state policies did not increase actual time spent in PE or recess, did not affect average body mass index (BMI) or BMI Z score, and did not affect the prevalence of overweight or obesity. CONCLUSION: Increasing the PE or PA time required or recommended by state laws has not slowed the obesity epidemic. Many schools have failed to comply with state laws. A back-of-the-envelope calculation suggests that, even with better compliance, the legislated changes in PE laws might not have changed energy balance enough to reduce obesity prevalence.

Inserção de profissionais de educação física no Sistema Único de Saúde: análise temporal (2007-2021) / Insertion of physical education professionals in the Unified Health System: temporal analysis (2007-2021)

O objetivo desta pesquisa foi descrever e analisar a série temporal da inserção de profissionais de educação física (PEF) no Sistema Único de Saúde (SUS) no período de 2007 a 2021, bem como apresentar a distribuição por regiões e estados de profissionais no território brasileiro. Trata-se de um estudo descritivo e de série temporal que utilizou dados secundários oriundos do sistema de consultas do Cadastro Nacional dos Estabelecimentos de Saúde (CNES). Analisou-se o quantitativo de PEF no SUS nas cinco regiões e nos vinte e seis estados e no Distrito Federal entre 2007 e 2021 e reali-zou-se a análise temporal para verificar a distribuição dos PEF nas regiões brasileiras. Os resultados apontam para um crescimento no número de PEF entre 2007 (n = 22) e 2020 (n = 7.560) em todo o país. Em 2021 observa-se uma redução de 2,8% no quantitativo de PEF. Entre as regiões, os maio-res quantitativos foram observados nas regiões Nordeste e Sudeste, enquanto nos estados a maior concentração foi em Minas Gerais, seguido de São Paulo, Pernambuco, Bahia e Rio Grande do Sul. Observou-se uma tendência crescente de PEF nas regiões Norte e Sul. Conclui-se que o quantitativo de PEF atuantes no SUS teve um crescimento expressivo durante o período analisado, sendo fruto das políticas públicas e programas voltados à promoção da atividade física constituídos ao longo do tempo. Apesar disso, há importantes disparidades geográficas que não devem ser desconsideradas, reforçando a necessidade de estratégias coletivas e investimentos em políticas públicas que fomentem a inserção dos PEF na rede assistencial e de fortalecimento do SUS

The aim of this study was to describe and analyze the time series of physical education professionals (PEF in Portuguese) in the Unified Health System (SUS in Portuguese) from 2007 to 2021, as well as to present their distribution by Brazilian regions and states. This is a time series study which used secondary data from the Consultation System of the National Registry of Health Establishments (CNES in Portuguese). We analyzed the number of PEF in the country, in the five Regions and in the twenty-six States and the Fed-eral District between 2007 and 2021 and the temporal analysis was carried out to verify the distribution of PEF in the Brazilian regions. The results point to an increase in the number of PEF between 2007 (n = 22) and 2020 (n = 7560). In 2021, there is a 2.8% reduction in the amount of PEF. Among the regions, the highest numbers were observed in the Northeast and Southeast regions, while in the states the highest con-centration was in Minas Gerais, followed by São Paulo, Pernambuco, Bahia and Rio Grande do Sul. There was an increasing trend in the distribution of PEF in the North and South regions. The number of PEF working in the SUS had an expressive growth during the analyzed period, being the result of public policies and programs aimed at promoting physical activity constituted over time. Despite this, there are important geographic disparities that should not be disregarded, reinforcing the need for collective strategies and financ-ing in public policies that encourage the insertion of PEFs in the care network and the strengthening of SUS

An overview of injury prevention for soccer players in Pakistan: A sports rehab perspective.

Soccer (football) is one of the most popular weight-bearing sports in the world, which involves activities such as jumping, running and turning. Soccer related injuries have the highest incidence in all sports and are more common in young amateur players. The most important modifiable risk factors include neuromuscular control, postural stability, hamstring strength and core dysfunction. The International Federation of Football Association introduced FIFA 11+; an injury prevention programme for reduction in the rate of injuries in amateur and young soccer players. It focusses on the training of dynamic, static and reactive neuromuscular control, proper posture, balance, agility and control of the body. This training protocol is not being used in Pakistan at amateur level who neither possess the resources, nor the knowledge or proper guidance in risk factor assessment, prevention, and subsequent sport injury management. In addition, the physicians and rehabilitation community are not much familiar with it except for those directly involved in sports rehabilitation. This review highlights the importance of including FIFA 11+ training programme in the curriculum and faculty training.

Warm-up optimization in amateur male soccer players: A comparison of small-sided games and traditional warm-up routines on physical fitness qualities.

The aim of this study was to compare the effects of small-sided soccer games (SSSGs) and traditional warm-up (TWU) routines on physical fitness qualities in soccer players. Following a between-subject, randomized design, amateur-level soccer players were assigned to a SSSG warm-up (n = 10; age: 19.3 ± 2.8 years) or TWU group (n = 10; age: 19.3 ± 2.4 years). Players completed multiple trials of 10-m and 30-m linear sprints, change-of-direction speed (CODS) tests, and countermovement jumps (CMJ) prior to and following the warm-up routine. Separate mixed ANOVAs were performed to assess group effects (SSSG vs. TWU), time effects within each group (pre- vs. post-warm-up), and their interaction for each physical fitness quality. No significant interaction effects were observed for any dependent variable. Significant improvements were evident between baseline and follow-up measurements for 10-m sprint time (p = 0.002, Hedges' g effect size [g] = 0.59) and CMJ variables (height: p = 0.016, g = 0.20; power: p = 0.003, g = 0.19; force: p = 0.002, g = 0.14) in the TWU group and for CODS performance time (p = 0.012, g = 0.51) and CMJ variables (height: p < 0.001, g = 0.46; power: p = 0.002, g = 0.35; force: p = 0.001, g = 0.27) in the SSSG warm-up group. Both SSSG and TWU protocols improved selected physical fitness qualities with SSSG more effective at improving CODS and CMJ performance, and TWU more effective at improving linear speed. Soccer coaches may choose between SSSG or traditional warm-up activities according to player needs and preferences; however, the superior effects of SSSG suggest it might offer greater benefits than TWU in preparing players for optimal physical output.

Physical demands and psychophysiological stress in young athletes team sports / Exigências físicas e estresse psicofisiológico em jovens atletas de esportes coletivos

ABSTRACT Training monitoring is important in the development process of the athlete. The objective of the study was to characterize the psychophysiological response and physical demands of soccer, basketball, handball, and volleyball with young athletes. The sample consisted of 61 young athletes of both genders and members of team sports, 10 training sessions for each modality were monitored. The psychophysiological responses were monitored by the session rating perception of exertion (Session RPE) and training impulse (TRIMP). The physical demands were, distance covered (DC), DC by speed zone (DC_Z1, DC_Z2, DC_Z3, DC_Z4, DC_Z5), number of sprints, and duration of the session. In addition, the recovery status (TQR) was also collected. Differences were noted between duration (p<0.001), DC_Z1 (p<0.017), DC_Z2 (p<0.05), DC_Z3 (p<0.05), DC_Z4 (p<0.003), DC_Z5 (p < 0.05), sprints (p < 0.001), TRIMP (p<0.02), Session RPE (p<0.05) and TQR (p<0.007). In psychophysiological responses, handball showed more time in zones 4 and 5 than other modalities. According to physical demands, basketball, and handball had a higher number of sprints and also higher values ​​in DP_Z5. Therefore, the simultaneous monitoring of physical demands and psychophysiological responses provides supplementary information in monitoring young athletes.

RESUMO O monitoramento do treinamento é importante no processo de desenvolvimento dos atletas. O objetivo do estudo foi comparar as respostas psicofisiológicas e as demandas físicas de jovens atletas de futebol, basquete, handebol e voleibol. A amostra foi constituída por 61 indivíduos de ambos os gêneros que foram acompanhados ao longo de 10 sessões de treino de cada modalidade em questão. As respostas psicofisiológicas foram monitoradas através da percepção subjetiva de esforço da sessão (PSE da sessão) e o impulso de treinamento (TRIMP). As demandas físicas analisadas foram a distância total percorrida (DP), DP por zona de velocidade (DP_Z1, DP_Z2, DP_Z3, DP_Z4, DP_Z5), número de sprints e a duração das sessões. Além disso, o estado de recuperação (TQR) também foi analisado. Foram observadas diferenças significativas entre a duração das sessões (p<0,001), DP_Z1 (p<0,017), DP_Z2 (p<0,05), DP_Z3 (p<0,05), DP_Z4 (p<0,003), DP_Z5 (p <0,05), número de sprints (p < 0,001), TRIMP (p<0,02), PSE da sessão (p<0,05) e TQR (p<0,007). Nas respostas psicofisiológicas, o handebol apresentou mais tempo nas zonas 4 e 5 em comparação demais modalidades. Nas demandas físicas, o basquete e o handebol apresentaram maior número de sprints e também maiores valores na DP_Z5. Dessa forma, o monitoramento em conjunto das demandas físicas e respostas psicofisiológicas fornecem informações complementares no monitoramento de jovens atletas.
