(A) will make people mentally dependent
In fact, for sports, sometimes mental dependence is not a good thing. When we engage in high-intensity exercise, we will produce a substance called "Maca-like" in our body, which will increase with the increase of college students' exercise intensity. This substance can cause excitement and addiction of college students. In the long run, when college students stop exercising for some reason, it will affect their emotional changes. Will become anxious, depressed and so on, and even cause changes in physical function. Therefore, no matter which exercise mode college students choose, they must follow the principle of moderation, otherwise it will do great harm to our health.
② It will increase the load on the heart.
I think everyone who has had sports experience knows that the first physical change after a certain exercise is the acceleration of the heartbeat, so the same thing will happen to college students after exercise. But if you do high-intensity exercise, the acceleration of the heartbeat will definitely put a burden on your heart. If this happens frequently, it will inevitably have a bad influence on the heart of college students, and even lead to the possibility of sudden death.
(3) It is easy to cause dehydration and insufficient support.
High-intensity exercise will definitely cause sweating, and the source of sweating is the water in the human body. Therefore, when college students are engaged in high-intensity exercise, a lot of sweating will cause a lot of loss of water and vitamins in the body. At this time, due to insufficient water supply in the body, college students will be very weak, thus affecting the physical condition of colleges and universities. At the same time, high-intensity exercise will also cause insufficient blood supply to the human body. Because of high-intensity exercise, the body function can not be reasonably circulated, which will lead to hypoxia and insufficient blood supply, making college students uncomfortable.
