Beet Root Juice Supplementation Improves Exercise Performance. Nitrate Content of the Beets Decreases ATP Turnover in High Intensity Exercise.
Nitrates have long been decried as toxic and dangerous and I bet, before their latest appearance to the supplement market, none of you would even have remotely considered to consciously increase his/her dietary nitrate supply. Yet, recent scientific studies confirm that nitrate (in moderate doses) is not only safe, but also has, its effects on vasodilation aside, quantifiable effects on exercise performance. A group of scientists from the UK tried to find out the underlying mechanisms of the ergodicity of supplemental nitrate ( Baily. 2011 ). Following a six day supplementation period in the course of which seven males (aged 19-38 yr) consumed 500 mL per day of either nitrate-rich beetroot juice (~300mg nitrate content) or placebo (PL, with negligible nitrate content). What they observed is best described as a "tuning effect" that was observable both, in the course of high, as well as in the course of low intensity exercise training. During low intensity exercise ,...
