Relevant information shows that roller skating is a very safe sport. The impact of inline skating is not as good as jogging, so it is often used as a rehabilitation project for sports injuries. As long as you follow the corresponding safety precautions, it is quite safe to practice roller skating. Safety advice for roller skating friends: 1, warm-up activities. Just like taking part in any sports, you should warm up before each practice, and roller skating is the same. Let the main joints of the whole body move and pull the tendons, especially the ankles, knees, thigh joints and waist. 2. Wear protective equipment. A complete set of protective gear should include: helmet, elbow pads, knee pads and palm pads. Before each roller skating class or outdoor exercise, check whether the roller skating shaft and screws are loose, and tighten them if they are loose; 3. Use common sense to choose safe occasions. Don't play roller skating on the driveway, slope, oily or stagnant ground; Use common sense to judge and put safety first. Let yourself have a more eye-catching safety sign when exercising in a poorly lit venue. 4. Know your own level and know your own limits. When you play roller skating, you should be guided and be especially careful when you want to learn new skills or movements according to your own situation. 5. Find a good coach to come to class, accumulate professional knowledge and roller skating skills, and get the safety knowledge of roller skating from the coach. 6. You can't gallop on the main road, so as not to cause irreparable harm. The traffic law also expressly stipulates that it is illegal to play roller skating on the road. 7. Learn how to stop and fall safely, so as to reduce the chance of falling and the degree of injury. The training of safe falling is to disperse the impact of falling through protective gear and whole body. When you fall, keep your body falling forward, avoid falling backwards or completely bearing the impact of a certain part of your body, such as hips, chin, wrists, elbows, knees, etc., so as to reduce the degree of injury to a single part. The general advice is to lean forward, kneel down, get down, slide forward with your palms on the ground, and let your body stretch out at the same time, and then throw yourself to the ground completely. After this series of actions, the impact force when you fall will be completely dispersed, so that a single part will not be hurt too much. In view of the declining age of roller skating enthusiasts, Ke Jiming reminded parents that children under the age of 7 should not learn roller skating. Because roller skating requires the legs to be turned outwards, the bones of children under 7 years old are immature, which easily leads to X-shaped legs. However, we can learn from roller skating: 12 years old children should be carefully guided by professionals. Experts believe that children under the age of 12 are in a critical period of physical development, and long-term roller skating will lead to excessive leg muscles and affect the all-round development of the body. In addition, when playing roller skating, the waist, knees and ankles need to support the body hard. Once the force is improper, these parts are very vulnerable to injury. So in general, children under 12 are not suitable for long-term roller skating. Children should play roller skating under the guidance of professionals, and at the same time, if conditions permit, not on the street or in places with traffic safety hazards. For example, some parents just buy some equipment and let their children learn roller skating by themselves, which can easily cause injuries to feet, waist and other parts. This is a big thing for children, and you must not be careless.
