Beetroot juice has been connected in studies to a stronger athletic performance in athletes performing intermittent high intensity efforts. Beetroot juice, which contains inorganic nitrate, has been shown to increase the concentration of nitric oxide in the blood. Nitric oxide has many functions in the body including increasing blood flow to muscle fibers and ultimately making energy. This is useful for all athletes who perform short high intensity segments with rest in between, namely swimmers, cyclists and runners.
Several studies have found that beetroot juice helped lengthen the time it took for muscle fatigue and helped with the power associated with muscle turnover. For runners (swimmers and cyclists), have you tried drinking eating a beet or drinking beetroot juice prior to performance or competition? What were the results?
