Abstract
The nutritional supplement of athletes before and after exercise determines their performance in the competitive process. This study aims to explore the effect of protein supplementation on athletes’ physical fitness. This article takes 48 male and female athletes as experimental subjects and randomly divides them into 6 groups. The experiment period was 8 days, and each group was supplemented with protein every day. During the experiment, the athlete collected 10 ml of elbow venous blood for the first time in a quiet fasting state in the laboratory at 8 am. Two hours after the main class (after relaxing), go to the laboratory to draw 10 ml of venous blood from the elbow twice until the 8th day. Then, the chemical immunoassay method is used to measure the blood insulin content, and then the analysis device is used to measure the composition of various compounds in the blood before and after exercise. After 1 week of nutritional supplement intervention, the H2O2 content of each experimental group was significantly reduced after acute high-intensity exercise stimulation compared with the non-intervention situation, and the reduction in the intervention group (A) was more significant (P < 0.01). The research results show that scientific sports nutrition supplements can effectively improve the body’s endurance to high-intensity sports training. Sports nutrition and health products can improve the physiological function of athletes, accelerate the metabolism of lactic acid, promote heart and lung function, and accelerate the recovery after physical training.
