Resumo
O principal objetivo do estudo é analisar o efeito agudo do treinamento em trampolim (ET) sobre estabilidade, altura de salto e velocidade em corrida de 20 m de líderes de torcida. Foram recrutados 53 sujeitos (18 homens e 35 mulheres), pertencentes ao programa Pura Vida Athletics (Tibás, Costa Rica). Três grupos foram formados aleatoriamente: Grupo Trampolim (GT), Grupo Controle (GC) e Grupo de Treinamento Normal (GEN). O GT realizou um treinamento de trampolim (ET) tradicional (com uma duração aproximada de 45 min e intensidade de 75-85% da frequência cardíaca máxima). Foram realizadas medições pré-teste e pós-teste de estabilidade (centro de pressão), velocidade de 20 metros e altura de salto (CMJ). Com relação à estabilidade, em bipedestação, o GT piorou significativamente (p <0,05 *) comparado ao GC e, nas posições liberty, awesome e arebesque, o GT piorou significativamente (p <0,05 *) comparado aos GC e GEN. A altura do CMJ do GT foi significativamente menor (p <0,05 *) com relação ao GEN, mas não ao GC. A velocidade de 20 m do GT diminuiu significativamente (p <0,05 *), enquanto o GC (p> 0,05) e o GEN (p> 0,05) não apresentaram uma alteração significativa. Como conclusão, ficou evidente uma diminuição significativa na estabilidade do GT em bipedestação e nos elementos de stunt liberty, awesome e arebesque. A altura do CMJ do GT teve uma diminuição não significativa. A velocidade de 20 m do GT foi significativamente menor após o ET.
