This study aimed to investigate the effect of an exercise session with weights associated with glutamine dipeptide (GLD) supplementation on cognitive function of people living with HIV/ AIDS. The sample consisted of 10 HIV+ women, who used the Antiretroviral Therapy Highly Active. The participants were randomized in a double-blind procedure to receive seven days of supplementation GLD or placebo (PLA). At the end of this first period, the participants held a workout with weights with cognitive assessments before and immediately after the session. To evaluate oxidative stress markers blood samples were collected before and 1 hour and 2 hours after the session.Then the participants rested for 7 days for the initial stocks of glutamine return to baseline levels (washout). Following was realized the crossing of the groups, so those who had received the GLD in the first week spent extra for 7 days with PLA and vice versa, and then they repeated evaluations and exercise session. The exercise session consisted of seven resistance exercises involving different muscle groups, with three sets of 8-12 repetitions with an interval of 90 seconds between sets and 120 seconds between the exercises. Stroop test was used to cognitive assessments, which aims to assess selective attention and inhibitory control over the color of conflict and word, and the N-back test, responsible for evaluating the central executive component of working memory by stimuli visual. Oxidative stress markers (TBARS, FOX, GSH, GSSG, AOPP) were analyzed in plasma samples.
