Before participating in outdoor sports (such as Yangtze, Taijiquan, etc.), you should do preparatory activities to gently stretch the knee joint, increase the flexibility and agility of the lower limbs, and let the knee joint move before participating in sports. When practicing leg press, do not lift your legs too high to prevent excessive strain on knee ligaments and muscle tissue; when playing taijiquan, the range of motion should not be too large and the squatting position should not be too low to prevent injury to the knee joint from being overloaded. 5, cycling is a good way to exercise the knee joint under non-weight bearing. However, when riding a bicycle, the height of the seat should be adjusted to sit on the seat with both feet in the pedals, both legs can be straight or slightly bent, the seat is too high, too low or uphill when pedaling hard, the knee joint have adverse effects, should be careful to avoid. 6, when the temperature drops in winter, the knee joint is cold vasoconstriction, blood circulation becomes poor, often making the joint stiff, pain aggravated, so in cold weather should pay attention to keep warm, if necessary, wear a knee brace to prevent the knee joint cold. 7.
