The transition of the human body from a quiet state to an exercise state requires an adaptation process. Preparatory warm-up exercises before starting exercise can improve the excitability of the nerve center and cardiopulmonary function, increase the blood flow of the muscles, increase the body temperature, increase the activity of biological enzymes, promote metabolism, and make the extensibility of muscles, tendons and ligaments are in good condition. The internal resistance is reduced, so that the functions of all aspects of the body are coordinated, and the optimal state of exercise is gradually achieved.
Warming up before exercise makes tendons more flexible because it raises body temperature and increases joint range of motion, thereby avoiding joint, ligament, and muscle damage.
Warming up before exercise can help speed up the blood circulation of the body and gradually increase the body temperature. In particular, the local body temperature rises more rapidly at the sports site.
Warming up before exercise can also help exercise mental activities, help to regulate psychology, establish neural connections between various motor centers, and make the cerebral cortex in the best state of excitement.
Doing warm-up activities can increase the metabolism of muscle tissue, increase heat production and increase body temperature; the increase in body temperature may increase metabolism, thereby forming a "virtuous circle". The body is in a good state of stress, which is conducive to formal exercise. In addition, elevated body temperature also enables the release of oxygen in the blood to tissues, ensuring the supply of oxygen and improving the function of the nervous system.
It takes about 3 minutes or so for the body to realize how much blood it needs to deliver to the muscles. So the warm-up should last approximately 5-10 minutes and should be accompanied by stretching of major muscle groups.
