Abstract
Dietary nitrate supplementation can improve blood pressure and contractile function of type II (fast twitch) muscle fiber contraction and force production. However, limited data are available for women and dosing guidelines for women. The purpose of this study is to investigate if nitrate ingestion, provided as nitrate-rich beetroot juice, improves blood pressure and countermovement jumps and cycling sprint performance compared to nitrate-depleted beetroot juice placebo in women. Eight recreationally active women have been assigned in a randomized, double-blind, crossover design to three experimental conditions to receive: (1) 2 x 70 ml of concentrated nitrate--depleted beetroot juice placebo (PL; 0.10 mmol nitrate- total); (2) 1 x 70 ml of PL and 1 x 70 ml of nitrate--rich beetroot juice (BR-LOW; ~6.0 mmol nitrate- total); (3) 2 x 70 ml of BR (BR-MOD; ~12 .0 mmol nitrate- total). Participants underwent body composition testing and a ramp incremental cycling test for the determination of peak power output and maximal aerobic capacity. After a familiarization, participants performed an experimental protocol, consisting of resting blood pressure, blood samples, and training load/stress obtained. Then, participants performed 5 x vertical countermovement jumps interspersed by 1 min of recovery, and 6 x 6-s all-out cycle sprints interspersed by 24-s of recovery. One-way repeated measures ANOVAs will be used to analyze differences across conditions in performance for vertical countermovement jumps and cycling performance. A subset of data (n=8 out of 18) for cycling sprint and countermovement jump performance is presented. These data will provide insight on the efficacy of dietary nitrate as an ergogenic aid for exercise performance in healthy women.
