About

The purpose of this study is to determine the effects of nitrate-rich beetroot juice supplementation on exercise performance in female rowers when accounting for habitual vegetable nitrate consumption.

Full description

The objective is to use a stratified block randomization, double-blind crossover trial to test rowing ergometer exercise performance after drinking a beetroot juice supplement and compare it to the same test after consuming a placebo (a nitrate-free version of the beetroot juice supplement) in a convenience sample of athletes from a single Division 1-A collegiate women's rowing team.

Before testing, the participants' habitual vegetable nitrate consumption will be assessed from their report of foods consumed in the past 24 hours. Estimates of dietary nitrate intake will be calculated from the quantity of vegetables consumed and used to determine whether dietary nitrate intake influences the efficacy of the beetroot juice supplement.
