Resumo

OBJETIVO: Avaliar os efeitos de um protocolo de fadiga global de curta duração sobre os parâmetros cinemáticos da marcha de indivíduos saudáveis.
MÉTODOS: Fizeram parte da amostra 21 adultos jovens saudáveis. Foi realizada a análise de parâmetros da cinemática linear (velocidade, cadência, comprimento do passo, largura do passo e tempo do passo) e angular da marcha (flexão e extensão dos quadris; flexão e extensão dos joelhos; plantiflexão e dorsiflexão dos tornozelos) antes e após a realização de um protocolo de fadiga global de curta duração. Para a avaliação da marcha, foi utilizado um sistema de captura da trajetória tridimensional da marcha, composto por um sistema de cinemetria dotado de 7 câmeras integradas. O Protocolo de Fadiga de Agilidade Funcional de Curta Duração, que consiste em um protocolo de fadiga global de curta duração com séries de exercícios de agilidade funcional, foi utilizado para fadigar os participantes. Para as comparações entre as avaliações pré e pós-fadiga, os valores médios de cada avaliação foram utilizados e submetidos ao teste t pareado, e nível de significância adotado foi p < 0,05.
RESULTADOS: Não houveram diferenças estatisticamente significativas nos parâmetros angulares e lineares avaliados, exceto para cadência (p = 0,03).
CONCLUSÕES: O protocolo de fadiga global de curta duração não alterou os parâmetros angulares e cinemáticos da marcha em indivíduos jovens, exceto a cadência que se mostrou mais elevada após o protocolo de fadiga.
