Elderly people have the habit of morning exercises. In the park in the morning, either practice Tai Chi or walk slowly, in short, the purpose is to sweat. However, some elderly people exercise joints, often referring to the exercise methods of middle-aged and young people, desperately practicing bone and joints, performing long-distance running, bending over, repeatedly squatting, etc., and emphasizing movements in place. In fact, when you get old, you should make some adjustments in terms of exercise intensity and exercise mode.

　　According to clinical experience, human After ageing, bones and joints have different degrees of aging. Maintaining the bones and joints of the elderly is like maintaining an old bicycle. It must be refueled and pedaled frequently, but it cannot be used for long roads and heavy loads. The same is true for the elderly to maintain bones and joints. They must exercise regularly, but they cannot exercise for a long time and overload. Because the joints of the elderly are damaged, it is difficult to recover. At the same time, it is necessary to keep the joints warm in cold weather.

　　Dr. Konan believes that the elderly should be targeted for exercise. For patients with knee osteoarthropathy or rheumatoid arthritis, try not to practice Tai Chi or mountain climbing. When playing Tai Chi, the knee joint is in a semi-flexed state, the pressure in the joint cavity is increased, and the squatting position is too large, which may cause leg pain and cramps. If you particularly prefer Tai Chi, according to your own situation, it is recommended that the movement range be smaller. Do not squat too low, and do not play several sets in a row to prevent damage to the knee joint due to excessive load.

　　Climbing is a relatively intensive sport. As the saying goes: "It is easy to climb a mountain, but difficult to descend a mountain." When going down a mountain, it has high requirements for leg muscles. At the same time, it has a strong impact on the knee and ankle joints. Regardless of your physical condition, blind exercise not only fails to achieve the purpose of strengthening the body, it may also cause the relapse or aggravation of the old disease.

　　 Dr. Conan suggested that such elderly people should choose swimming or walking on the ground as their main exercise program. In addition, when you participate in physical exercise, you should prepare for the activity, gently stretch the knee joint, let the knee joint fully open before participating in strenuous exercise.
