Effect of acute dietary nitrate intake on post-activation performance enhancement in male long jumpers (opens in new tab)

BackgroundThis study aimed to determine whether acute dietary nitrate supplementation enhances the post-activation performance enhancement (PAPE) response induced by squats performed with a 5% velocity loss (VL) threshold.MethodsA randomized, double-blind, placebo-controlled, crossover design was employed. 20 male long jumpers completed three experimental conditions: placebo (PLA), 5%VL, and beetroot juice (BRJ) + 5%VL. Approximately 2 h following the ingestion of 100 ml of BRJ containing 9.2...
