Efeito do uso de palmares na assimetria de força da braçada no nado crawl

Um estudo com nadadores recreacionais

Resumo

Enquanto a assimetria de força na braçada no nado crawl poderia prejudicar o desempenho, o uso de palmares é sugerido para reduzir essa diferença de força. Assim, o objetivo do estudo foi avaliar a assimetria de força dos membros superiores em nadadores recreacionais com palmares de diferentes formas e áreas e sem a utilização do implemento. Oito nadadores recreacionais realizaram 2 tentativas máximas de 10 segundos de nado estacionário em cada situação experimental (com palmar pequeno côncavo, médio côncavo, médio plano e sem palmar) enquanto as suas ações foram gravadas com uma câmera. As forças máximas dos primeiros 5 ciclos foram determinadas para as braçadas forte e fraca e para os membros dominante e não-dominante. Por meio de estatística paramétrica, a repetibilidade da força máxima e do índice de simetria determinado a partir da dominância lateral foi constatada sem e com palmares, mas não foi observado efeito da área e da forma de palmares sobre a assimetria de força. Contudo, quando os resultados individuais foram analisados, a assimetria de força variou entre as condições diferentemente para os participantes. Portanto, a assimetria de força dos membros superiores pode ser avaliada com o teste de nado estacionário realizado sem e com palmar a partir da dominância lateral, o que também permite uma melhor análise do que a assimetria estimada a partir das braçadas forte e fraca. Logo, o uso de palmares pode diminuir a assimetria de força, mas a escolha do palmar deve ser conduzida individualmente.
