Abstract
Although dietary nitrate supplementation may enhance muscle contractility in type II muscle fibers, few studies have examined the efficacy of nitrate supplementation on resistance exercise performance and in elite power-based athletes. The purpose of this study is to investigate whether acute and multi-day nitrate-rich beetroot juice (BR) ingestion elicits ergogenic effects on resistance exercise performance in NCAA Division I baseball athletes. Using a randomized, double-blind, crossover design, eighteen male collegiate baseball athletes will consume supplements for 8 consecutive days, 2.5 hours prior to exercise on experimental visits, under 2 conditions: 1) nitrate-depleted beetroot juice placebo (PL) or 2) BR (~6 mmol of nitrate). Subjects performed back squat and bench press at 55%, 60%, and 65% of their one-repetition maximum. Peak and mean power and velocity were measured using a linear transducer, and differences in performance across conditions and time will be analyzed using a two-way repeated-measures analysis of variance. A subset of data (n=14) for peak and mean power and velocity for back squat and bench press is presented. These data will provide insight into nitrate dosing guidelines for enhancing weightlifting in a sport-specific elite level population.
