Acute effect of juçara juice (Euterpe edulis Martius) on oxidative stress biomarkers and fatigue in a high-intensity interval training session: A single-blind cross-over randomized study

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...
