Red Wine an Exercise Killer in Older Men?
Starts With You
The benefits of red wine have been touted in recent years thanks in part to their antioxidants and tannins that have been linked to positive effects in heart health. That may still hold true, though a recent study finds that older men who drink red wine and exercise are basically canceling the benefits of their cardio out.
The study, published in the Journal of Physiology by researchers at the University at Copenhagen, found that resveratrol -- an antioxidant found in red wines -- reverses the positive health boost older men would normally receive from cardiovascular activity. The study took place over 8 weeks, following 27 men between the ages of 64-66. During those two months, all of the men participated in high-intensity cardio exercise, but only half took a 250mg dose of resveratrol done in a "double blind" fashion where the men and the researchers had no idea who was taking a placebo.
The results were startling, as the study states that "these findings indicate that, whereas exercise training effectively improves several cardiovascular health parameters in aged men, concomitant resveratrol supplementation blunts most of these effects." It also notes that "resveratrol administration also abolished the positive effects of exercise on LDL, TC/HDL ratio and triglycerides concentrations in blood," noting that the expected cholesterol-lowering properties of the antioxidant had vanished in this study.
The study's findings are limited to the specific age range, and only focus on those subjects who did regular high-impact cardiovascular exercise. There will likely be more research done, but resveratrol has a long history of being linked to positive health-boosting effects.
