Popis: This study aimed to evaluate the effects of juçara juice on oxidative stress biomarkers and fatigue in a high-intensity interval training (HIIT) session. Fifteen physically active men were assigned to drink 250 mL of juçara juice or water (control) 1 h before exercise. Blood samples were collected 1 h prior to exercise, immediately post exercise, and 1 h post exercise. From the relative average changes, a decrease in oxidative stress index was observed immediately post exercise (P = 0.020) and an increase in reduced glutathione 1 h post exercise (P = 0.044) in the juçara juice intake group in relation to the control. Juçara juice intake also promoted increases in plasma total phenols (P = 0.020), and uric acid (P = 0.001) over time. Moreover, individuals who consumed juçara juice presented lower fatigue compared to the control (P
