The fact that brisk walking is beneficial in preventing aging and adult diseases and maintaining good health is well accepted by the general public. When a person walks, the muscular system acts like a rotating pump that pushes blood back to the heart. Brisk walking speeds up the movement of the muscles, which promotes blood circulation throughout the body and accelerates metabolism, keeping our heart, immune system and other organs of the body in good condition and making people younger. At the same time, brisk walking has a good effect on the prevention of diabetes, heart disease, osteoporosis, stroke, etc. However, many of the patients who visit the bone and joint department of Tianjin People’s Hospital come because of joint pain and swelling caused by brisk walking. Why does this happen? The reasons are as follows: Brisk walking is indeed good for health, and can even prevent joint degeneration. However, brisk walking is not suitable for patients who already have arthritis, because it can aggravate the wear and tear of joint cartilage, which causes joint pain and swelling, and aggravate the wear and tear of joints, leading to further aggravation of joint degeneration. For people with knee osteoarthritis, swimming and walking are the best forms of exercise that do not increase the weight-bearing capacity of the knee joint, but also allow the muscles and ligaments around the knee joint to be exercised. Swimming is a whole-body exercise, which has a health effect on the cervical spine, shoulder joints and knee joints, etc. Moreover, swimming can make multi-organ functions such as heart and lung exercise, which can effectively enhance the ability to resist diseases. Walking is one of the most economical, safe and suitable for long-term adherence to the form of exercise, with arthritis when walking pace is not too large, the speed is not too fast. You can also do leg lifts in bed, using the thighs to drive the calves, the knee joint is not bent, if necessary, you can put a sandbag in the ankle to increase the intensity of the exercise, the advantage of this exercise is not limited by the site. Arthritis patients are not suitable for some strenuous activities, such as stair climbing, mountain climbing, fast squatting exercises, etc., because when people carry out these activities, the weight on the joints is 4-5 times more than normal, the joint load is too large and intensify the wear and tear of the joints. Of course, in practice, some activities cannot be avoided, such as going up and down stairs and squatting. You can take the method of slow walking, one step up and down the stairs, while pulling the handrail. When squatting, you should also hold on to something to reduce the stress on the knee joint and patella, which will reduce pain and wear. Riding a bicycle is desirable because most of your body weight is on the cushion when riding a bicycle, so the knee joint is under relatively little stress, and riding a bicycle keeps the joints mobile and strengthens the muscles around the joints.
