Biochemical Markers Of Oxidative Stress In Female Volleyball Players. Effect Of Consumption Of Passiflora Edulis

Objective: to examine the effect of the consumption of Passiflora edulis (P. edulis) on biochemical markers of oxidative stress (BMEOX) in female volleyball players of a university team. Method: population fourteen players (age: 19.3 +/- 2.2 years; mass: 57.5 +/- 5.0 kg; height: 1.62 +/- 6.2 m), were randomly divided into experimental group (EG) and placebo group (GP). During the seven days of the microcyde, the EG was given 2 ml / day of P edulis juice and the GP received 2 ml / day of placebo (flavored water). Blood samples were taken during days 1, 4, 7 and 14. Creatine kinase (CK), glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), creatinine (Cr), catalase (CAT), superoxide dismutase (SOD), lipid peroxidation by thiobarbituric acid reactive substances (TBARS) and glomerular filtration rate (GFR). Results: transaminases increased significantly on day 4, and decreased on days 7 and 14 in both groups. CK and Cr, increased, but did not return to baseline values on day 14.TBARS and CAT increased in both groups without significant differences, while SOD increased with significant differences for all days only in GP. Conclusion: The microcyde produces changes in the BM EOX, its level increase with the increase in its intensity; Consumption of P. edulis did not significantly affect transaminase, SOD and cxr activities, but these enzymes remain more stable in athletes who consumed P. edulis. It is necessary to deepen the knowledge about antioxidant uses and intense exercise.
