Study On The Effect Of Lepidium Meyenii Extract Anti-moving Fatigue For Male College Students

Objective:The purpose of this study was to investigate the anti-fatigue effect of maca as a natural sports nutrition supplement by comparing the sports performance of male college students before and after taking natural maca supplements.Research method:20male college students of Jilin Sport University of Physical Education and Sports major were recruited as subjects,and a randomized single-blind crossover experiment was conducted to divide all the subjects into two groups,with the experimental group taking maca extract for two consecutive weeks and placebo for two consecutive weeks after a week’s rest;the control group taking placebo for two consecutive weeks and maca extract for two consecutive weeks after a week’s rest.The content includes body composition test,blood biochemical index test,aerobic exercise ability test.The results of the study:1.After two weeks of supplementation with maca extract,compared with the control group,the indicators of physical composition of the subjects were not statistically significant（P>0.05）;2.After two weeks of supplementation with maca extract,compared with the control group,the time of exhaustive exercise of the subjects in the maca group was significantly（P<0.05）prolonged,VO₂max and O₂ Pulse were significantly improved（P<0.05）after two weeks of supplementation with maca extract,the endocrine-related indexes of TTE content was significantly（P<0.001）increased,COR content was significantly decreased（P<0.01）,fatigue-related indexes of CK and LAC content were significantly（P<0.05）decreased,and FFA content was significantly（P<0.05）decreased in the maca group compared with the control group.FFA content was significantly increased（P<0.05）.The study concluded that the two-week supplementation of maca extracts had a significant effect on promoting the recovery of athletic fatigue in male college students and accelerating the rate of energy metabolism in the body after exercise.At the same time,the active ingredients in maca extract have good repair function for tissue cell damage,so maca extract can play its potential as a natural plant-based sports nutrition supplement in the direction of anti-sports fatigue and improving sports performance.
