Contrary to popular belief, use of the supplement resveratrol (RSV) may not actually enhance the effects of high-intensity interval training (HIIT).

Many news outlets and health blogs have long recommended RSV as a complement to exercise and to enhance performance. However, results from a study by Queen’s researcher Brendon Gurd suggest that RSV may actually impede the body’s response to training.

“The easiest way to experience the benefits of physical activity is to be physically active,” says Dr. Gurd, a professor in the School of Kinesiology and Health Studies. “The efficacy of RSV at improving metabolic and cardiovascular functions is not as profound as was once thought.”

Results after the four-week study showed that RSV supplementation may actually oppose the effects of exercise alone. In fact, the placebo group showed an increase in some of the benefits associated with physical activity as opposed to the group taking RSV whose physical fitness didn’t improve.
