Resveratrol: not so good for physical performance?
Available as a dietary supplement, resveratrol has, according to its sellers, the ability to optimize the benefits of physical activity, thus improving performance. However, a study presented by researchers at Queen’s University, Ontario, Canada, specifies that theeffects of resveratrol would be harmful to the body, altering the benefits of regular physical activity.
A supplement that can modify physical adaptation
This study was carried out over a month, on 16 participants practicing a sports activity on a regular basis, at least three hours a week. During these four weeks, a first group of candidates received regular doses of resveratrol, and a second group received a placebo. The researchers’ findings show thatthis substance opposes the effects of physical exercise. After various physical tests (stress tests…), the group without resveratrol supplementation shows a clear improvement in physical performance, while participants who have absorbed this substance remain at the same level and show no improvement.
This research needs to be conducted more broadly to verify these conclusions, however, this study shows the negative impact that resveratrol confers.
The effects of resveratrol
Naturally present in red wine, or chocolate, resveratrol has many benefits already known. It has anti-inflammatory properties, and preventive against diabetes, as well as cardiovascular diseases. In addition, it also helps prevent certain cancers or Alzheimer’s disease. Another study even mentions its “anti-aging” abilities.
Research presented by Jama Internal Medicine reveals that the beneficial effects of resveratrol are not accurate, and states that dietary consumption has little or no influence on inflammation, cancer, cardiovascular disease or longevity, especially in the elderly.
Queen’s School of Kinesiology and Health Sciences professor Brendon Gurd explains, “Resveratrol’s ability to improve metabolic and cardiovascular function is not as universal as previously thought.”
The latest observationsseem to refute the benefits of resveratrol, especially in terms of health and nutrition. However, additional studies must be carried out to affirm these hypotheses and prove the impact of dietary consumption of resveratrol on our body.
