In sports, such as the shoulder joint, elbow joint, ankle joint, wrist joint, finger joint, elbow joint, wrist joint and ankle joint, there are many activities, so it is necessary to prepare for these joints and carry out appropriate activities at the same time to avoid sudden and intense exercise from damaging joints or muscles, such as wearing knee pads and wrist pads and appropriate exercise intensity. Then the answer is: shoulder joint. Wear knee pads and wrist pads, move your joints slowly with moderate intensity during exercise, and don't do dangerous and difficult movements. How to walk in outdoor sports can minimize knee injury: First, study how your feet touch the road.

If you want to climb on foot for a long time, such as going up the steps, you should stop and have a rest from time to time, because long-term climbing will wear the knee joint the most. Climbing for 20 minutes and stopping for 3 minutes can relieve the tension in the knees. It is also important to choose a flat road as far as possible. Rugged and stony roads will increase the frequency of knee torsion and the wear of joints will be greater. Developing good walking habits and mastering scientific mountaineering skills can also effectively prevent knee joint injuries. Knee joint injuries are mostly caused by impact, unstable center of gravity sprain, accidental fall and joint dislocation. Then the root of these three situations is the center of gravity, and the stability of the center of gravity is the top priority of safety. When walking on a flat road or a small slope, you should grasp the center of gravity, have rhythm and flexibility, and land your feet lightly. Don't step too big and don't step too fast. Pay attention to 1 hour and take a proper rest for 3 minutes.

If you climb with a heavy load, pay attention to moderate weight. When climbing, the center of gravity moves forward, then climb the legs to find the support point, and use the center of gravity to drive the hind legs to keep up naturally, instead of pulling the body up and wrapping it with the body and muscles. Try not to run when going downhill, keep your center of gravity back, bend your knees and push your feet outward. Pay attention to the effects of rheumatism and colds. In addition to sports injuries, external rheumatism and colds are also the enemy of joints. When walking, the joints need to be hot and sweaty. It's okay to walk. Don't blow for a long time during rest, and don't let your knees get wind directly in summer. Rest is to avoid the direct wind and move your body slightly to avoid sudden cooling of your body, which will lead to cold knees. Change into dry underwear. When there is no condition to dry joints in winter, you should exercise to warm up before drilling sleeping bags. Finally, you should raise your awareness of knee health.
