Strengthen the material metabolism of bone exclusion, maintain and improve the elasticity and toughness of bone, so as to delay the aging process of bone cells. At the same time, "Yun" fitness can make muscle fibers thicken, improve the contraction, conductivity, reactivity of muscle fibers, make muscles and ligaments more tough and powerful, delay the decline of muscle function.
Among them, cardiovascular problems are often faced by the elderly health problems, exercise and fitness can enhance the function of cardiovascular system. Appropriate physical exercise can increase cardiac excitability, enhance myocardial contractility, make coronary artery dilate, improve blood circulation, and improve myocardial oxygen utilization capacity. At the same time, exercise can also reduce blood fat, delay vascular sclerosis, reduce the incidence of cardiovascular diseases.
Often participate in sports activities, due to the needs of muscle activities, the function of the digestive system is strengthened, the gastrointestinal peristalsis is strengthened, the blood circulation is improved, the secretion of digestive fluid is increased, and the absorption of nutrients is accelerated. For the elderly with weak digestive system function, exercise and fitness can help improve their digestive function.
The elderly respiratory system function level is low, aerobic exercise can be a good exercise respiratory system, improve its function. Regular participation in physical exercise, especially appropriate aerobic exercise, can enhance the strength and endurance of respiratory muscles, increase lung ventilation, improve alveolar ventilation rate, maintain the elasticity of lung tissue and the range of motion of the chest, and delay the aging spurt caused by insufficient alveolar activity. Exercise and fitness for the respiratory system has another advantage: through the improvement of the function of the respiratory system can improve the metabolism of the whole body internal organs, strengthen the function of the whole body internal organs. 2. It is very helpful for the elderly to maintain the function of the internal organs.
The decline of nervous system function is also a health problem faced by the elderly. Often participate in physical exercise, can improve the function of the central system, delay brain aging. Exercise and fitness can improve the excitability of cerebral cortex nerve process, shorten the reaction time, improve the function of brain center. Exercise and fitness can also prevent cerebral arteriosclerosis, maintain good blood supply to the brain. In addition, exercise and fitness can also improve neuromuscular function and enhance the body's balance, coordination and control, which has a positive effect on preventing falls.
