The next time you hear about an athlete “juicing,” he may be beetroot juicing.
A pair of recent studies have found that athletes who throw down some beetroot juice before an event tend to do better from an endurance standpoint. In November, a study appearing the Journal of Applied Physiology found that runners who beetroot juiced increased their endurance by 15 percent during high intensity running. And a study just published in the journal Medicine and Science in Sports and Exercise finds that competitive cyclists are likewise affected. (Beetroot juice has also been found to lower blood pressure and cleanse the kidneys and gall bladder.)
