Sponsor's own description
Beetroot juice is a rich source of nitrate (NO3-), which serves as a precursor to nitric oxide (NO) via the NO3- to nitrite (NO2-) to NO conversion pathway. This pathway is believed to enhance vasodilation and improve neuromuscular function, such as by increasing sarcoplasmic reticulum calcium release and re-uptake, leading to enhanced force production in type II muscle fibers and improved muscle contractile recruitment. Therefore, the aim of this study was to investigate the effects of beetroot juice supplementation on muscle contractile properties, as assessed by tensiomyography, and neuromuscular performance in sprint-trained athletes.
