In recent years, research on exercise adjuvants to enhance exercise capacity and fatigue recovery is very active. Supplementation of auxiliary chain amino acids can inhibit the production of 5-HT during exercise and has the effect of preventing fatigue. Therefore, this article mainly studies the effects of branched-chain amino acids taken by contestants in the strength competition. In this experiment, 36 football players were selected and randomly divided into an experimental group (n=18) and a control group (n=18). The total duration of the experiment is 6 weeks, with 5 days training per week. Each training time is 90 minutes to ensure that the training intensity of the two groups matches. After training every day, the experimental group drank a glass of water containing BCAA, and the control group drank mineral water. At the beginning of the test, saliva and venous blood samples will be collected when waking up in the morning, and the thigh speed will be measured in the afternoon. Repeat the above index test at the end of the test. Using YEAGER gas analysis and cardiac function analysis system, physiological parameters during exercise can be collected. The experimental data showed that before the start of the experiment, the INS levels of the control group and the 20mg group were significantly different (P>0.05), and the 20mg group was 36.57% and 25.31% higher than the control and 40mg groups, respectively. It turns out that supplementing branched-chain amino acids does not significantly affect the body's normal metabolism. After supplementing BCAA, endurance athletes can speed up lactate clearance after exhaustive exercise, stabilize blood glucose level during long-term sub polar exercise, and increase serum enzyme GOT and GPT after long-term sub polar exercise, which can reduce and delay the occurrence of fatigue in exercise.
