NCT05210244

Brief Summary

Whereas beetroot juice (BJ) supplementation is shown to increase physical performance in endurance activities, its benefits in neuromuscular function and strength performance has been barely studied. In this cross-over randomized placebo-controlled study, we investigated the effects of BJ acute supplementation in improving neuromuscular performance in amateur climbers
