why exercise is important

There are many exercise principles in sports training, in which the principle of gradual step by step is the most basic of the original step, The In the exercise of the body if you follow this principle, you can better improve the physical and prevent excessive fatigue and sports trauma. Generally speaking, in the grasp of certain motor skills, the new technical action is always based on those already master the action on the basis of, for example, the movement of the "diving forward" is built on the "roll forward" basis. If the violation of this progressive principle, like a child will not go to learn the same first, not only less effective, and even make the body hurt. In addition, the functioning of the various organs of the body must have the necessary adaptability to the movement to be carried out, so that the load is increasing and gradually strengthened. The amount of exercise can not be increased by a short period of time. When the body does not have the conditions to participate in the training of large sports to participate in the intense movement and competition, then the body is certainly can not afford. Because of the amount of exercise, changes in the human body are different, such as moderate intensity activities, the pulse frequency of 120 to 140 times per minute, such as intense exercise up to 180 times or even 200 times. At this point for the impact of motor organs and internal organs is extremely profound, can increase blood pressure, breathing faster, blood redistribution, increased metabolic effects. To meet these requirements, it takes some time to adapt to the process. The gradual increase in the amount of exercise can make the body's adaptive process gradually increased, so that the activities of motor organs and internal organs to coordinate well. In the exercise or exercise training, if the violation of the principle of gradual, not only impede health, prone to sports trauma, excessive fatigue, but also fail to exercise the body to enhance physical fitness and improve the performance of the purpose. Therefore, in the exercise of physical and sports training, we must follow the principle of gradual and orderly.
