Muscle tissue changes with age, resulting in decreased muscle tension and muscle strength. After the age of 25, the fat rate will drop by 3%~5% every 10 year, which is mainly due to the decrease of exercise intensity, the change of life attitude and the decrease of the utilization rate of the central nervous system. After 50 years old, the quality of muscle tissue will plummet, with an average replacement of 5-10% every10 year. If you don't have other muscle training around the age of 60, muscle loss is the primary reason for becoming a foreigner, and it is an inevitable problem brought about by age growth and physical aging.

Only by finding a way to reduce the rate of muscle loss can we achieve the goal of slowing down aging. To relieve muscle loss, muscle training is essential. Compared with young people, middle-aged and elderly people must maintain a higher amount of exercise. Therefore, the elderly should not have inner pressure in muscle training. In terms of physical fitness, energy is the most important performance and the easiest to improve. There is no need to be afraid, and there is no foundation. From freehand training to small instrument practice, dumbbell practice, from wide net weight to heavy weight, it is gradually upgraded. "People are old first, and muscle training begins gradually from the legs. Squat is a very worthwhile gesture! The relative density of human bone is stronger than that of ultrasound.

It can be reduced by about 30% every 10 year. The reduction of ultrasonic bone density improves the degree of osteoporosis in human body, because osteoporosis makes the spine of the elderly more sensitive, the back bends, leading to hunchback and difficulty in walking, which brings great inconvenience to daily life. Women suffer from more severe osteoporosis than men. Muscle training is particularly important. The outflow of muscle tissue causes the relative density of human bones to decrease, which in turn leads to aging and a series of fractures. Therefore, both boys and girls, especially women, should pay more attention to muscle training. Muscle training can slow down the outflow of relative density of human bones, reduce the prevalence of cardiovascular diseases, improve the ability of balance and coordination, and avoid falling.

In addition, aerobic endurance exercise should be improved. When carrying out energy theme activities, resting heart rate can be reasonably reduced, blood pressure and blood sugar can be improved, and cardiovascular load can be reduced. The combination of aerobic training and muscle training can delay aging to the greatest extent, and the diet should be balanced and reasonable, with the dietary guidelines of China citizens as the specific guidance. It is not recommended to take tonics and Chinese herbal medicines indiscriminately and recuperate by yourself. Diet conditioning is the best way to slow down aging. The importance of rest and sleep is extremely critical for the elderly. Most of the repair of the human body is carried out during sleep, and muscle training is tiring. Therefore, good periodic sleep quality is the key. It is not only the quality of sleep, but also a kind of release and rest.
