As the saying goes, “walk a hundred steps after a meal and you will live to be ninety-nine”, and in Chinese medicine, it is also said that “when the four bodies are shaken, the five grains are eliminated”. This is actually the importance of exercise. So is any exercise is good for us? Obviously not, if you do not pay attention to the way, time and amount of exercise, not only not beneficial, but also cause sports injuries. Let’s talk about the physical characteristics of the elderly: first of all, the human body into old age after the organs into the degeneration stage, some also combined with some chronic diseases. In terms of the motor system, the joints are also degraded, the joint cartilage has different degrees of wear and tear, and severe pain often occurs. Secondly, osteoporosis is also a common problem, due to different personal habits, gender differences, genetic differences and obviously different, some people have no obvious performance, some people have obvious osteoporosis pain, serious even if the slightest activity may occur osteoporotic fracture. So how do you choose the right exercise for you? From the perspective of sports medicine, there are several notes: 1, the elderly should not choose too strenuous way, try not to carry out weight-bearing exercise, such as climbing, climbing, running, deep squatting, etc., these sports will form a greater wear and tear of the lower limb joint cartilage, long-term will cause cartilage degradation accelerated, and serious joint pain and effusion, resulting in prolonged discomfort. You can choose aerobic exercise, such as slow walking on level ground, swimming, gymnastics, etc., can consume a lot of energy, but also can make the whole body’s musculoskeletal exercise, which can significantly slow down the progress of osteoporosis, reduce the degradation of muscle power, and wear and tear on the joint cartilage is also significantly reduced. 2, the length of time and the amount of exercise should be how to grasp it, for usually very little exercise for the elderly, in the beginning of exercise, should master the principle of gradual progress, do not compare with others, according to the ability of each person to set, it is best to exercise will be sweating, or have a small sweat, and soon disappear after rest. Increase the amount of exercise cycle is not too short, it is best to weeks or months to measure, so that the whole body organs have a longer preparation, not to appear overworked. 3, the so-called “winter training three nine, summer training three volts” is not suitable for the elderly, the elderly exercise should avoid drastic weather changes, because too cold or too hot will cause rapid changes in cardiovascular and cerebrovascular pressure, prone to vascular accidents. Can achieve the purpose of exercise can be, the temperature of the environment should choose more comfortable as well, do not force excessive stimulation. Finally, I wish the elderly friends can enjoy the fun of life from the exercise, and at the same time have a good body, get a happy, healthy old age.
