Physical exercise is of great benefit to the elderly to balance their mental and psychological state, improve their metabolism, enhance the stability of nervous system function, prevent the decline of organ function, improve their immunity, delay aging and accelerate the recovery of physical function after illness. Several rehabilitation exercise methods for common diseases of the elderly for reference. (1) Physical exercise of coronary heart disease is an integral part of comprehensive treatment of coronary heart disease, which is helpful to reduce the occurrence and mortality of myocardial infarction. You can do moderate-intensity aerobic training such as walking and jogging. It is observed that running for 3000m in 16 minutes or 5000m in 26 minutes can reduce the cholesterol in blood by 350mg1l. Tai Ji Chuan and Qigong can also be used, and the heart rate is generally controlled at around 130 beats/min. Be careful not to exercise during angina pectoris attack and myocardial infarction focus has not been repaired. Geriatric researchers suggest that the critical period of heart disease in the elderly is between 3-8 am, when blood pressure is the highest and it is easy to die of stroke. If you do inappropriate exercise at this time, you are particularly prone to accidents. Therefore, it is recommended to exercise around 10 am. Every time you go out for exercise, you should carry a health care box (first aid box) with you. (2) Hypertension According to the survey, no matter what occupation, the higher the degree of physical activity, the lower the incidence of hypertension. Except those who are seriously bedridden due to illness, all kinds of hypertensive patients can do outdoor physical exercise, with many items, such as walking, jogging, Tai Ji Chuan, medical gymnastics, badminton and cycling. Although the amount of exercise can be increased appropriately, the heart rate should not exceed 130 beats/min. Don't hold your breath, spin fast, exert yourself too hard, bow your head deeply and so on. (3) Obesity and diabetes obesity are one of the important factors to promote the occurrence and development of diabetes. Proper exercise is an important means to treat diabetes, and the therapeutic effect of exercise on type II diabetes (non-insulin-dependent diabetes). It is more direct, safer and more effective than drugs, and this effect is not limited by age. You can increase the consumption of fat and sugar through muscle exercise, thus reducing obesity, lowering blood sugar and urine sugar. The principle of physical exercise in treating diabetes and obesity is the same, that is, physical exercise should be combined with diet control. Methods include walking, jogging, Tai Ji Chuan, etc. Walking at normal speed consumes 837 dry cokes per hour. If you speed up, you can consume 1255- 1506 kilojoules per hour. Every consumption of 14644 dry coke can reduce body fat by 0.45 kg. If you don't increase your diet, walking for an hour every other day can reduce fat by 0.65 kg a month and 8 kg a year. The physical condition of diabetic patients is generally poor, so it is advisable to start with mild activities, and with the enhancement of physical fitness, the amount of exercise can be gradually increased. Suitable sports include walking, Tai Ji Chuan and radio practice. Strenuous exercise should be avoided to avoid acidosis caused by lactic acid accumulation caused by hypoxia; At the same time, we should also pay attention to not exercising after insulin injection and before eating (on an empty stomach) to prevent hypoglycemia (easy-to-absorb sugar should be carried with you for application in case of hypoglycemia). (4) Chronic bronchitis can improve the adaptability to external temperature changes and enhance the disease resistance. Especially insist on cold-resistant exercise. The method is to rub the exposed parts of the head, face and upper and lower limbs by hand several times a day for a few minutes at a time until the skin turns red. In summer, use a cold water towel, wring it out and rub it all over your body, 1-2 times a day, and wash your nose with cold water; After beginning of autumn, wash your face, wipe your body, or take a cold bath with cold water, and persevere. In addition, you can practice breathing exercises, because deep breathing exercises not only exercise the respiratory muscles, but also change the pressure in the lungs, force the residual gas in the alveoli to be discharged, increase air exchange, and are also very beneficial to the elastic recovery of alveolar tissue. The location is chosen by the lake; Woods and parks are better. (5) Periarthritis of shoulder joint, referred to as scapulohumeral periarthritis for short, is a unique geriatric disease, which usually occurs in people aged 50-60. The pain around the shoulder is severe at the onset, especially at night; In the later stage, the movement of shoulder joint is limited, and the clinical treatment course is long and the effect is not obvious. Besides massage and other treatments, physical exercise is the most effective. Methods Active joints were the main methods, and the range of joint motion was from small to large, and finally the range was as large as possible. For example, use healthy limbs to raise the head of the affected limb, use the affected hand to shape the back, use the affected limb to climb the wall and so on. In addition, ballroom dancing can prevent and treat scapulohumeral periarthritis, which is very suitable for middle-aged and elderly patients. Thinkers with cervical spondylosis should insist on doing neck rotation every day. (6) Chronic lumbocrural pain is mainly caused by degeneration of lumbar joints, chronic strain of lumbar muscles and myasthenia. Should give priority to with waist, back and leg muscle exercise. There are Tai Ji Chuan, wuqinxi, gymnastics, race walking, jogging, gateball and walking backwards. Walking backwards can dredge the meridians, strengthen the waist and strengthen the body. It can be held twice a day for 5- 10 minutes each time, which is particularly effective for lumbar muscle strain. Don't exercise too much, so as not to cause new injuries.
