Effects of Beetroot Juice Intake on Performance and Physiological Parameters

This study was a randomized, double-blind, crossover design for 3 weeks. In the first week, a researcher explained all the experimental procedures to the participants. In the following two weeks, the participants attended the Exercise Physiology laboratory to be assessed in 2 rowing ergometer sessions, separated from each other by a washout period of 7 days, under the same environmental conditions. In both strictly identical sessions, the participants randomly ingested beetroot juice (BRJ) or placebo (PL) 3 hours before the start of the tests.
