Resveratrol could boost performance22 June 2012Consuming red wine polyphenol resveratrol could improve performance by enhancing strength and endurance, according to a new research project. Experiments in rats showed that heavy consumption of the compound which occurs naturally in red wine, fruit and nuts to encourage better physical performance, muscle strength and heart function. The study, which was published in the Journal of Physiology, also found improvements in energy metabolism. The rats demonstrated a higher force response in muscles during isometric contraction and a more rapid whole body oxidative metabolism. Based on these findings, we conclude that resveratrol is an ergogenic aid that improves exercise training via changes in skeletal muscle function and cardiac performance, but also improves energy metabolism,” said the researchers. The researchers also noted improved left ventricular function and energy homeostasis. This was attributed resveratrol changing signalling pathways and gene expressions. Research leader Jason Dyck from the University of Alberta, Canada likened the effect of resveratrol to undertaking endurance exercise training and noted the commercial potential of taking the compound. Dyck outlined plans to test resveratrol on diabetics with heart failure over the coming months to examine whether consumption can improve heart function. "I think resveratrol could help patient populations who want to exercise but are physically incapable. Resveratrol could mimic exercise for them or improve the benefits of the modest amount of exercise that they can do," said Dyck. "It is very satisfying to progress from basic research in a lab to testing in people, in a short period of time." | |
