Resumo(s)
de competição e os tempos de exposição são elevados implica riscos. Objetivo: Avaliar efeitos
de um programa de Força Reativa, no Controlo Postural (CP) e na Prevenção de Lesões músculoesqueléticas
dos Membros Inferiores em Jovens Atletas. Métodos: 15 atletas (18,75 ± 0,75 anos)
distribuídos por 2 grupos: Grupo experimental (GE-7) e Grupo de controlo (GC-8). O GE realizou
um programa de exercícios pliométricos. O CP foi avaliado em dois momentos, através de uma
plataforma de pressão. As variáveis estudadas foram: deslocamento de centro de pressão (DCP)
e área de oscilação (AO) para tarefas estáticas; e pico inicial de força (PIF) e tempo de
estabilização (TE) para tarefas dinâmicas (saltos). Resultados: Os valores relativos às lesões
assemelham-se aos da literatura, contudo verificou-se que a severidade e os tempos de paragem
após lesão foram inferiores aos de outros estudos. Verificaram-se reduções no TE (redução
significativa na condição SLI_UE), reduções no PIF (redução significativa na condição SLI_UE).
Conclusões: Severidade e tempo de paragem em atletas de Voleibol e Basquetebol, melhoria em
duas das variáveis do controlo postural em tarefas dinâmicas – TE e PIF, parecem beneficiar da
aplicação de um programa de exercícios pliométricos. Em futuros estudos recomenda-se a
obtenção de dados nas componentes AP e médio-lateral, determinação exata do PIF, a introdução
de exercícios com mudança de direção, bem como alargamento da amostra.
Introduction: Participation in Sports has health benefits, but when the level of competition and the times of exposure are high entails risks. Objective: To evaluate the effects of a Reactive Force program on Postural Control (CP) and Prevention of Musculoskeletal Injuries in Young Athletes. Methods: 15 athletes (18.75 ± 0.75 years) divided into 2 groups: Experimental Group (GE-7) and Control group (GC-8). The GE performed a plyometric exercise program. The CP was evaluated in two moments, through a pressure platform. The variables studied were: pressure center displacement (DCP) and oscillation area (AO) for static tasks; and initial force peak (PIF) and stabilization time (TE) for dynamic tasks (jumps). Results: The values resemble with those of the literature, however, it was found that the severity and stopping times after injury were lower than those of other studies. There were reductions in the TE (significant reduction in the SLI_UE condition), reductions in the PIF (significant reduction in the SLI_UE condition). Conclusions: Severity and stopping time in athletes of Volleyball and Basketball, improvement in two variables of the postural control in dynamic tasks - TE and PIF, seem to benefit from the application of a program of plyometric exercises. In future studies it is recommended to obtain data on the anteroposterior and medio-lateral components, exact determination of the PIF, the introduction of exercises with change of direction, as well as enlargement of the sample.
