Osteoporosis is a common and frequently-occurring disease in the elderly, especially in postmenopausal women. Once an old man with osteoporosis falls down carelessly, he is prone to fracture, which not only affects his longevity and health, but also brings great difficulties to his life and economy. Therefore, the prevention and treatment of osteoporosis in the elderly is of great significance for improving the quality of life of the elderly and enjoying their old age.
Although bones are hard, they are organs with very active metabolism. It is always renewed and reconstructed at the same rate as old bone absorption with 3% to 5% new bone formation. The absorption of old bones gave way to new ones. Once the formation of new bone slows down, the absorption of old bone appears to accelerate, so osteoporosis appears. Research shows that, except for the elderly, China Air Force personnel who stay in bed for a long time and lose weight are prone to osteoporosis.
Exercise has a great influence on bones. This is because the inorganic bone salt, which accounts for two-thirds of the total weight of the spine, is tiny crystal particles, and each gram of bone salt contains 10 particles, and their surface area can reach 100 square meters. When they are under pressure, they wear each other to produce piezoelectric potential, and the weak current formed by the potential difference can promote osteogenesis, balance bone formation and absorption, and prevent bone loosening. Therefore, only when the elderly participate in sports and make their bones stimulated by pressure and traction can they be beneficial to the formation of new bones and prevent osteoporosis.
Data show that 30-60 minutes of light exercise, such as jogging, doing exercises, playing Tai Ji Chuan, fencing, qigong and dancing, can delay bone loss and prevent osteoporosis. In addition, moderate exercise for the elderly is not only beneficial to bone health, but also can prevent many chronic diseases. However, the elderly, especially those with osteoporosis, should avoid strenuous exercise to avoid excessive exercise and fracture.
