The nitrate juice produced better cycling performance when compared to the placebo. On a 16.1 km race beet juice reduced the total time by 2.7% – not much, but presumably enough to matter in a competition.
In any case, this is fun for doping discussions. Should we ban athletes from quaffing beet juice?
