Exercise is a set of rules involving physical strength and skills, and it is also a behavioral activity constrained by habits, which is usually competitive. There is no object that does not move, and there is no movement that can leave the object. Movement is conservative, that is, it can neither be created nor destroyed, but its concrete forms are diverse and can be transformed into each other, and the total amount of movement remains unchanged during the transformation.
Movement is the inherent nature and existing mode of matter, and it is the inherent fundamental attribute of matter. There is no matter that does not move, and there is no movement without matter. Movement is conservative, that is, it can neither be created nor destroyed, but its concrete forms are diverse and mutually transformed, and the total amount of movement remains unchanged during the transformation.
Benefits of exercise:
Exercise can enhance the metabolism of human body, and physical exercise can promote the ability of tissue cells to absorb and utilize sugar, and increase the storage of liver glycogen and muscle glycogen. At the same time, because fat is a rich energy substance in human body, the energy released by its oxidative decomposition in the body is about twice that of the same amount of sugar or protein.
Exercise can slow down the heart rate at rest and during exercise, reduce the working time of the heart and increase the function of the heart. Regular physical exercise, especially stretching and chest expansion, can strengthen the strength of respiratory muscles, and chest expansion is conducive to the growth and development of lung tissue and lung expansion, thus increasing vital capacity.
