Summary

The aim of this study is to investigate Lepidium meyenii (Maca) extract supplementation on exercise-induced responses of the biochemical, and physiological parameters.

Detailed description

Thirty healthy male participants were divided into Maca group (2.25 g of Maca extract, twice per day for 12 weeks) and placebo group (n = 15). All participants conducted a graded exercise test on treadmill to determine the maximal oxygen consumption (VO2max) before and after supplementation, and the speed equivalent to 70% VO2max was conducted for an exhaustive endurance exercise test by treadmill for 1 hours, followed by 90% VO2max until exhaustion.The time to exhaustion, peak oxygen consumption, maximal heart rate and average heart rate will be recorded during the exercise period. Venous blood samples will be drawn before, immediately after, 2-hour after, 4-hour after, and 24-hour after the exhaustive endurance exercise test. Data was analyzed by Two-way mixed design ANOVA.
