In this study, 30 male athletes were used to evaluate the effects of two different nutrient composition sports foods on human exercise performance, physical fitness recovery, and fatigue level through crosstrial and self-control experiments. The test results showed that: in the case of fasting blood glucose at the same level, the blood sugar concentration of sport food A was higher than sport food B after 20 minutes of consumption, while blood sugar concentration is higher than sport food B after 60% VO_2max exercise 50 minutes. After exhaustive training, the lactic acid scavenging efficiency of sport food A was significantly higher than that of sportfood B at five time points of 3, 6, 9, 12 and 15 minutes. Compared with sprot food B, the exercise food group A had higher values at the 10 time points after exhaustive training. The serum testosterone/cortisol ratio of sports food A was higher than the number of sports foods B and the control group. In the case of continuous consumption, sport food A is superior to sport food B in maintaining the ability to exercise, improving physical fitness and relieving fatigue.
