Beetroot juice and exercise performance

摘要

Abstract: Increased sales and consumption of organic and natural foods reflect consumers heightened interest in promoting health and improving athletic performance. Of these products, beetroot and its constituents have become increasingly popular in the arena of exercise performance, mainly due to the high concentrations of nitrate. Studies have indicated beetroot juice (BRJ) may improve exercise time to exhaustion, running performance, and increase muscular efficiency during moderate intensity exercise. The purpose of this review is to examine the efficacy of BRJ to serve as an ergogenic aid in athletic performance. It appears that BRJ may provide modest performance enhancement; however, more research is needed to clearly identify mechanisms of action and proper dosing patterns to maximize the performance benefits of BRJ.
