Understanding physique and promoting health

All kinds of movements that people master in sports can make people more accurate, coordinated and agile in completing all kinds of production and life movements; Physical exercise exercises the nervous system and cardiovascular system, which can improve the resilience and tolerance of the human body to the fast-paced life; The entertainment of sports can overcome people's psychological obstacles such as resistance, fear, boredom and impatience to the fast-paced life, and enhance people's self-confidence to the fast-paced life. So, what are the specific effects of physical exercise on promoting physical health? 1. Physical exercise can promote the growth and development of bones. Physical exercise can promote blood circulation, increase blood supply to bones, make bone tissue in vigorous osteogenesis get more raw materials, and accelerate the process of osteogenesis. At the same time, the pressure of running and jumping on bones during physical exercise is also a mechanical stimulus to promote bone growth. Only when the bone is stimulated by a certain load can the cells of epiphyseal cartilage proliferate normally. Someone has been studying the calcium metabolism of normal young people in bed for a long time. The results show that maintaining normal bone mineral metabolism depends on the longitudinal pressure on the long bone.
