Effect of the Beetroot Juice in Portuguese Swimmers

Summary

Objective: To investigate whether an acute intake of beet juice (BJ) improved the factors of total and split times (performance), stroke frequency and CMJ (biomechanics), lactate and HR (physiology) and RPE-TQR (psychophysiological) in a repeated (performance), stroke frequency and CMJ (biomechanics), lactate and HR (physiology) and RPE-TQR (psychophysiological) in a repeated maximal speed swimming effort in elite swimmers. Methods: A total of 18 elite swimmers participated in this randomized, double-blind study. In 2 different trials, swimmers ingested a Beet-It injection (70 ml placebo (PL) or a Beet-It injection of 70 ml beet juice (BJ)) 3 hours before undergoing a 2x6x100 m intermittent maximal speed crawl performance test.
