NCT05294198

Brief Summary

There is no evidence that beetroot extract (Beta vulgaris L.) is advantageous for the recovery of cardiovascular parameters and the autonomic nervous system (ANS) after submaximal aerobic exercise. The objective of this study is to evaluate the effect of beetroot extract supplementation on the recovery of cardiorespiratory and autonomic parameters after a submaximal aerobic exercise session. Healthy male adults will perform a cross-over, randomized, double-blind, and placebo-controlled trial. Beetroot extract (600mg) or placebo (600mg) will be ingested 90 minutes before evaluation in randomized days. Systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse pressure (PP), mean arterial pressure (MAP), heart rate (HR), and HR variability (HRV) indexes will be recorded at Rest and during 60 minutes of recovery from exercise.
