It's been known for a while now that reservatrol, a compound found in the skin of grapes and other fruits, and yes, red wine, has many health benefits. Back in 2006, a study published in the journal Cell, reported that reservatrol, the compound found in "significantly increased their (mice) aerobic capacity, as evidenced by their increased running time and consumption of oxygen in muscle fibers."
Check out this new study (Resveratrol May Be Natural Exercise Performance Enhancer) that found high levels of the compound improved exercise performance due to changes in skeletal muscle and heart function in rats.
You can find the abstract here (Improvements in skeletal muscle strength and cardiac function induced by resveratrol during exercise training contribute to enhanced exercise performance in rats)
Don't start drinking red wine just yet. According to one researcher, Resveratrol does not exist in wine or grapes in a high-enough amount to provide any significant health benefits or problems, the authors explained. Human trials with any relevant findings have used resveratrol doses equivalent to 667 bottles of red wine (1gm of resveratrol).
