Abstract
While dietary nitrate supplementation can enhance type II fiber contractility, the ergogenic potential of nitrate is relatively unexplored in explosive-type modalities and populations such as resistance exercise and power-based athletes. PURPOSE: To investigate if acute and chronic nitrate ingestion, provided as nitrate-rich beetroot juice (BR), improves resistance exercise performance nitrate-depleted beetroot juice placebo (PL) in male National Collegiate Athletic Association (NCAA) Division I baseball players. METHODS: Eighteen male collegiate baseball athletes (NCAA Division I), who are position players (i.e., not pitchers) were randomized in a double-blind, crossover design to consume 1) PL (negligible nitrate) and 2) BR (~6 mmol of nitrate) 2.5 h prior to performing exercise. Peak and mean power and velocity, and the within- and between-day coefficient of variation (CV%), were measured using a linear transducer during barbell squats and bench press performed at 55% one-repetition maximum (1RM), 60%1RM, and 65%1RM. RESULTS: Pilot data have been collected (n=4). All CV% data for peak power, mean power, peak velocity, and mean velocity wereCONCLUSION: Data collection is ongoing for n=18. These data will contribute to informing dietary nitrate supplementation guidelines in a population-specific manner and provide insight to the efficacy of nitrate on resistance exercise performance in power-based athletes.
