Abstract

Oxidative stress is defined as “the imbalance between oxidants and antioxidants, in favor of the first, which leads to a rupture of the control and physiological signaling that normally exerts the redox system, leading to molecular damage.” Physical exercise, especially resistance, increases energy demands at the muscular level, increasing the oxidative capacity of the myocyte. At the molecular level, this is reflected in an increase in mitochondrial density, an increase in the amount of ATP produced and, consequently, in a higher production of ROS. In studies carried out by our research group, they were able to demonstrate in vitro the antioxidant capacity of the aqueous and ethanolic extracts of leaves and juice of Passiflora edulis, probably due to its high polyphenolic content. The purpose of the study is to determine the effect of the consumption of Passiflora edulis on markers of oxidative stress in soccer players. 22 apparently healthy men from the soccer team of the University of Quindío, voluntarily participated in the study. The subjects and the experimental procedures to be developed were explained to the subjects. Afterwards, the subjects interested in participating voluntarily signed an informed consent letter. The study was conducted during a shock microcycle of a developer mesocycle. The subjects were divided into experimental group (GE) and placebo group (GP). During the 7 days of the microcycle, the GE consumed juice of Passiflora edulis and the placebo GP. The blood samples were immediately processed to determine markers of oxidative stress.
