The principle of increasing exercise: 1, doing more exercise can improve the blood circulation of human body, enhance the body's absorption of nutrients, improve the growth ability of bone cells, and mechanical force can promote calcium precipitation in bones, making bones strong and solid. 2. Exercise is an important condition for human development. Exercise is not equal to labor, and the constant repetition of the latter is not good for height. Increasing exercise should be a completely coordinated exercise to make the body develop. 3. Before the epiphyseal cartilage of young children has stopped proliferating, regular physical exercise is helpful to stimulate the proliferation of epiphyseal cartilage. 4. Stretching the spine, kicking the legs and the buoyancy of water are beneficial to the increase of the spine and limbs. 5. At both ends of the long bone, there is a kind of epiphyseal cartilage that specializes in bone growth. When the epiphyseal cartilage keeps proliferating in adolescence, the bones keep growing. Generally, when the epiphyseal cartilage stops proliferating in adulthood, the stature stops growing. Ways of increasing exercise: 1, stretching exercise. Including aerobics, fitness (fitness food) exercises, rhythmic exercises, unarmed exercises, stick-holding exercises, pull-ups, pendants, swings, loops on single and double poles, stretching exercises such as chest extension, kicking and swinging, leg press, and swimming in summer are also good items for limb stretching activities. 2, lower limb movement. Including skipping rope, high jump, pole vault, long jump, vertical jump, one-legged jump, bipedal jump, stair climbing, mountain climbing, hiking, walking, skating, roller skating, skiing and so on. 3. Systemic exercise. Including basketball, volleyball, table tennis, tennis, badminton and other ball games and boating. Good methods of increasing exercise play a great role in children's height. Take a deep breath and adjust the window to let the air circulate, put your feet together and stand naturally. This is a breathing conditioning method that should always be observed in the way of increasing exercise. Everyone can study together, which is also a foundation to ensure the increase.
