From the perspective of physical training, the improvement of physical fitness is the best means to prevent injuries. Physical quality here refers to the overall quality of your body. Simply put, your body's large muscle group, small muscle group, deep muscle group and stable and flexible core strength have all reached a certain standard. And there will be no compensation effect (compensation effect will deform the action, which probably means that when you do a technical action, the strength of your main contracted muscle is not enough to support you to complete this technical action, and then the muscles in other parts of your body will have compensation effect. For example, when doing strength training, if the load is too high, the strength of biceps brachii is not enough. You will bend down and lift your arms by the strength of your waist muscles. ) Because many people are obviously unbalanced. The accuracy of technical movements is also very important to prevent injuries, which requires physical stability, coordination, sensitivity and flexibility. If the technical action is done correctly, it is not easy to get hurt. The importance of preparatory activities can not be ignored. Warm-up activity is not a simple head exercise, and the most basic requirement of warm-up activity is sweating. Heat the body muscles. Here I recommend dynamic stretching training. This kind of stretching training can not only be used as an activity of high-level athletes, but also play a role in strength training for people with weak strength. Very good project, much better than impact stretching.
