Protein is a polymer compound composed of nitrogen, carbon, hydrogen, oxygen and other elements. It is the material basis for various metabolic activities in the human body. Physical exercise is a type of exercise carried out by means of physical exercise and exercise load to enhance physical fitness, improve physical and mental health, and improve and maintain the body's ability. The purpose of this article is to explore the interaction between sports and protein. This article describes the basic structure and function of protein, and conducts experimental research through several methods such as controlled experiments, protein qualitative and quantitative analysis and literature investigation. The results of the study show that the energy provided by different nutrients is significantly different during physical exercise. Among them, sugar can provide the highest energy, reaching 34%, followed by fat, which accounts for 33%, followed by protein. , accounting for 23% of total energy consumption. As the amount of exercise continues to increase, protein consumption and demand have basically increased significantly. In addition, different types of sports have obvious differences in the consumption, demand and supplement of protein. Among the four types of sports such as race walking, running, swimming and cycling, swimming has the largest consumption and demand for protein. The protein it consumed every 1 hour is 36.3g, which is 49.6%, 44.07% and 5.5% higher than race walking, running and cycling respectively.
