Ingredient in Red Wine Boosts Endurance

In an earlier post I talked about an ingredient in red wine called resveratrol which was linked to fat loss in a clinical study. Resveratrol is most abundant in Pinot Noir grapes (in their skin) which are used in the production of Pinot Noir wine.

What I didn’t mention was that in order to receive real benefits in fat reduction you would have to drink enormous amounts of red wine (over 100 glasses a day). For obvious reasons this doesn’t seem too practical.

What scientists sometimes do, however, is try to isolate a drug that contains sufficient amounts of the substance while minimizing the health risks.

In other words they may experiment with various doses of the drug in clinical conditions and test to make sure the drug doesn’t have any dangerous side effects. If it passes all the tests, they would then take the necessary steps to put it out on the market.

Resveratrol also Increases Endurance

Research has also shown that resvedratrol re-programs the muscles and may essentially double their endurance.

In this study, mice that were given relatively high doses of resvedratrol in their diets were able to run twice as far on treadmills than mice that weren’t given the supplement.

Evidence suggested that resvedratrol increased mitochondria in the cells. Mitochondria are like little energy packs in the body’s muscle cells. They are also involved in the process of burning fat for use of energy as required by the cells. This may also explain why the mice on the supplement were also thinner.

Experts speculate since the results of resvedratrol were so significant, athletes may quite possibly use it as a performance enhancer one day in the future.

Keep in mind that these studies are still in the animal experimental stages and there is no clear evidence yet on what dosage would be beneficial to humans.
