In order to improve their body performance, athletes often carry out long-term endurance training. The important factors that determine the endurance of athletes include their own metabolic level, physical and psychological responsiveness during exercise. The branched chain amino acids have a great influence on these factors. The purpose of this article is to study the effect of supplementing branched-chain amino acids on some hormone responses of athletes. Through the use of comparative experiments and radioimmunoassay, 20 volunteer athletes were recruited for a two-month experimental investigation. Modern measuring instruments and methods were used to record and observe the changes in the body-related hormones of supplemented branched chain amino acids and unsupplemented experimenters. In addition, in order to explore the specific effects of branched chain amino acids, the injection dose was controlled and grouped in detail. Research results show that branched-chain amino acids can adjust and improve some hormones in athletes’ plasma. Low content of branched chain amino acids can reduce the rate of decrease of T/C ratio in athletes by about 20% during exercise, and can increase their protein synthesis and metabolism rate by 10%. It can increase the growth hormone in the body by 2.3 index points, which can greatly relieve the athlete's sports fatigue.
