Exercise Physiology: A branch of human physiology, which is a science that studies human exercise ability, reaction and adaptation to exercise. This paper mainly studies the functional changes of human cells, organs and systems and their cooperative working ability and mechanism during exercise, and then observes its influence on human sports ability; At the same time, we should also observe the influence of exercise on the changes of human body shape and functional adaptability.

The main research task is to reveal the law and mechanism of physical exercise's influence on human function on the basis of a basic understanding of the law of human life activities, clarify the physiological principles in the process of sports training, physical education and physical fitness, and guide people of different ages, sexes and training levels to carry out scientific exercise, so as to achieve the purpose of improving competitive sports level, strengthening physical fitness, delaying aging and improving work efficiency and quality of life. Experimental research method is the basic method of sports physiology research. Through experiments, observe and analyze the changing process of human functional activities and their causal relationship, including animal experiments and human experiments.
