Growth hormone is secreted intermittently, and it is secreted more during sleep, exercise, tension and timely eating, while the concentration of growth hormone medium is relatively constant. When hungry, the relationship between growth hormone and growth hormone medium is opposite, that is, the level of growth hormone increases and the growth hormone medium decreases. Effect of exercise on the secretion of growth hormone Exercise can affect the secretion of growth hormone, and the metabolic reaction caused by exercise and exercise is not a simple linear relationship with hormones. This influence is restricted by the intensity and time of exercise, the training level of athletes and many internal and external environmental factors.

The influence of long-term exercise training on the secretion of growth hormone firstly shows that the exercise secretion reaction of growth hormone decreases with the adaptation of the body to the negative load of exercise.
