Resumo

Atividade física intensa pode aumentar o estresse oxidativo e danos musculares, causando fadiga e lesões. As meias de compressão graduada (MCG) podem diminuir esses efeitos deletérios. O objetivo foi determinar os efeitos agudos da MCG no dano muscular e estresse oxidativo (EO) em coletores de lixo. Treze coletores de lixo, 25,4 ± 5,2 anos, participaram usando MCG ou placebo. As amostras de sangue foram coletadas antes e após um dia útil e após 16 horas de descanso. Marcadores de EO e dano muscular foram avaliados. ANOVA de duas vias (duas condições e dois momentos) foi usada para á análise dos resultados. Não foram encontradas diferenças significativas para creatina quinase, catalase e glutationa peroxidase entre o tempo e os grupos. Houve uma diferença significativa para o conteúdo total tiólico e superóxido dismutase apenas no grupo controle (pré e pós, p = 0,004). O uso de MCG exerceu proteção aguda contra o aumento de marcadores de EO, mas não contribuiu para atenuar danos musculares.
