A new study headed by Dr. Brendan Gurd, employed as a professor at Queen's University in Canada, revealed that resveratrol, (RSV), found in the skin of red grapes and hence in red wine, inhibits the body's capacity to make best use of the effort of one's exercise regimen.

During the course of the study, Gurd examined 16 men who were physically active. Of them, eight subjects were given a dose of resveratrol on a daily basis. The other eight subjects were administered a placebo. After that, they did aerobic exercises for not more than three hours every week.

Post this; they were given directions to participate in High-intensity Interval Training (HIIT) thrice a week covering four weeks of the study.

At the end of the study, the researchers found out that those participants who had been administered placebo tasted several benefits linked with exercise. On the other hand, the participants who were given resveratrol did not show major improvements generally linked with exercise.

Gurd concluded the study by stating "The results we saw suggest that concurrent exercise training and RSV supplementation may alter the body's normal training response induced by low-volume HIIT.

The data set we recorded during this study clearly demonstrates that RSV supplementation doesn't augment training, but may impair the affect it has on the body."
