The lipid damage lipoperoxidation at the pre-exercise moment after 14 days of drinking varied according to the indicator used. To the best of our knowledge, this was the first study to evaluate the effect of grape juice consumption on oxidative stress and muscle fatigue parameters in judo athletes.

After evaluating the effects of grape juice consumption for 14 days on oxidative stress and muscle fatigue parameters in judo athletes, grape juice intake did not change upper limb muscle strength when compared to a placebo intake; however, an improvement in the antioxidant profile was seen when compared to placebo.

In the present study, upper limb and handgrip strength decreased after combat simulation, indicating that this exercise protocol was able to induce loss of muscle strength and fatigue. The reduction in handgrip strength, post-combat simulation, can be justified as judo is a sport that uses a lot of manual power to execute moves.

Similar results were found after a protocol of successive combat simulations on jiu-jitsu athletes Andreato et al. Physiological and technical-tactical analysis in brazilian jiu-jitsu competition.

Acute consumption of bordo grape juice and wine improves serum antioxidant status in healthy individuals and inhibits reactive oxygen species production in human neuron-like cells.

J Nutr Metab Regarding DNA damage, when comparing groups prior to the simulation of the fight, consumption of the grape juice resulted in less DNA damage than did placebo consumption.

However, after the simulation, DNA damage was similar to that of placebo consumption. A possible explanation is that the exercise protocol induced DNA damage, mediated by free radical species increased by acute exercise, and capable of modifying DNA via addition or hydrogen abstraction reactions, yielding a myriad of guanine oxidation products Cobley et al.

The basic chemistry of exercise-induced DNA oxidation: oxidative damage, redox signaling, and their interplay. Front Physiol 6: Consumption of grape juice prior to exercise may not be able to prevent this damage. A similar result was found in an article that analyzed the effect of consuming tomato juice, which rich in lycopene, on intense exercise on a stationary bicycle Harms-Ringdahl et al.

Tomato juice intake suppressed serum concentration of 8-oxodG after extensive physical activity. Nutr J Another feature found in this work was that athletes that consumed grape juice had increased total antioxidant capacity before and after fight simulation. The increase in total antioxidant capacity after grape juice consumption has already been previously demonstrated in healthy subjects chronically Yuan et al.
