The acute effects of beetroot juice on muscular endurance among recreationally active young adult males

This randomized, single-blind, placebo-controlled crossover trial investigates the acute ergogenic effects of beetroot juice on muscular endurance and perceived exertion among fourteen recreationally active young adult males. Participants consumed either 250 ml of beetroot juice or a nitrate-free placebo two hours prior to performing 90-second push-up and squat tests to measure objective repetitions and subjective fatigue via the Borg RPE scale. By incorporating a two-day washout period and specific performance metrics, the study addresses research gaps regarding the immediate impact of dietary nitrates on resistance-based endurance. The findings aim to clarify the utility of beetroot juice as a nutritional intervention for improving high-intensity muscular performance and managing perceived effort.
