RESUMO
As lesões e sobrecargas que envolvem o mundo desportivo são provocadas pela rigidez nos treinamentos e competições, associadas à pressão por um excelente rendimento, podendo acarretar danos musculoesqueléticos. O objetivo do estudo foi analisar o desempenho de estabilidade e flexibilidade muscular em atletas selecionados para a equipe brasileira de handebol da categoria infantil, que participaram do Acampamento Nacional de Desenvolvimento e Melhoria Técnica. O evento inclui treinos, análise de vídeo, jogos, uma palestra com um atleta da Seleção adulta e atividades como a foto oficial e um passeio. Os atletas foram avaliados na chegada ao acampamento e após 10 dias de imersão nas atividades esportivas. Participaram 20 atletas de 13 e 14 anos, nos quais foi avaliado o efeito de treinamento pré e pós aplicação de exercícios, por meio do teste de flexibilidade de sentar e alcançar modificado e do teste de estabilidade da extremidade superior em cadeia cinética fechada. Houve uma melhora significativa na amplitude de movimento na maioria dos casos, demonstrando um ganho real na plasticidade musculotendínea e uma melhoria no desempenho motor após o período de exercícios. Os exercícios de fortalecimento do manguito rotador e alongamentos são cruciais para potencializar esses avanços. Além disso, a atuação de profissionais de saúde, como fisioterapeutas e nutricionistas, é essencial para garantir um treinamento seguro e eficaz.
Injuries and strain in the sports world are caused by the rigidity of training and competitions, combined with the pressure for excellent performance, which can result in musculoskeletal damage. The objective of this study was to analyze the stability and muscle flexibility performance of athletes selected for the Brazilian youth handball team, who participated in the National Development and Technical Improvement Camp. The event included training sessions, video analysis, games, a lecture with a senior national team athlete, and activities such as the official photo and an outing. The athletes were evaluated upon arrival at the camp and after 10 days of immersion in sports activities. A total of 20 athletes, aged 13 and 14, participated, and the effect of pre- and post-training exercises was assessed through the modified sit-and-reach flexibility test and the upper extremity closed kinetic chain stability test. There was a significant improvement in range of motion in most cases, demonstrating a real gain in musculotendinous plasticity and an enhancement in motor performance after the exercise period. Strengthening exercises for the rotator cuff and stretching are crucial to maximizing these gains. Furthermore, the involvement of health professionals, such as physiotherapists and nutritionists, is essential to ensure safe and effective training.
RESUMO
To investigate the presence of burnout syndrome in child athlete tryouts for the Brazilian Handball Team, before and after the National Development and Technical Improvement Camp is of great interest. A correlational study, with longitudinal design of the before-and-after type, carried out with 64 male athletes in the children's category, immersed in the National Camp for Development and Improvement of Handball Technique, in the municipality of São Bernardo do Campo, São Paulo, Brazil, in December 2018. To evaluate burnout syndrome, we used the Athlete Burnout Questionnaire (ABQ). There was a statistically significant increase of the mean scores for burnout and dimensions (Physical and Emotional Exhaustion = 1.5 to 1.6; p-value < 0.001; Reduced Sense of Accomplishment = 2.7 to 2.9; p-value < 0.001; Sports Devaluation = 1.4 to 1.6; p-value < 0.001; and General Burnout = 1.9 to 2.0; p-value < 0.001). The athletes selected for the national team had lower mean scores for general burnout and dimensions (Physical and Emotional Exhaustion = 1.5; Reduced Sense of Accomplishment = 2.7; Sports Devaluation = 1.5; General Burnout = 1.9). The National Camp for Development and Technical Improvement can have a negative impact on the mental health of athletes. This event is important to select the competitors with greater ability to face the pressure and adversities present in the sport environment.
