Efeito agudo do trabalho aeróbico intermitente no estresse oxidativo e contagem de células sanguíneas de mulheres jovens treinadas

Abstract

The cells continuously produce free radicals and reactive oxygen species (ROS), which are neutralized by a defensive system in our body, and when this imbalance occurs, there is what we call oxidative stress. This article investigated the effect of acute intermittent aerobic work on oxidative stress and blood count of young women trained. The study included 17 women. We analyzed associations of the CBC TBARS, catalase and GSH. Observed differences between the groups, with no difference in catalase activity (p =, 017) for the practitioner group, ie, there was statistical significant difference between the catalase and rest immediately before exercise (p =, 013). This difference was also observed in the levels of TBARS (p = 0.02), the practitioners at rest and after training (p = 0.007) and between right after the workout and recovery (p = 0.004). However there was no statistically significant difference with the group practicing in GSH (p = 0.082). We conclude that oxidative stress occurred in an acute training.
