Motion injuries often occur in athletes, especially now competitive sport, by the force of each item in different parts of the damage are also different. Therefore, in order to avoid unnecessary damage during training, the coach is required to carry out targeted prevention and control of the athlete's sports injuries according to the characteristics of each project. The causes of sports injuries are generally the following: (1) Because the athlete's own physical quality is weak and the technical level is low, if the load is too large and the recovery is insufficient, or the movement is uncoordinated and standardized, it will cause a certain degree of external limb damage. (2) Constraints of sports venues: for example, cramps caused by unreasonable installation of equipment and low water temperature training. (3) Excessive exercise load causes the athlete to fatigue. Below I will analyze the self-generated characteristics of the four swimming positions: 1, breaststroke Among the four breaststrokes, the most technically strong, the athletes have higher flexibility requirements, and the athlete's ankle and knee flexibility have a certain effect on preventing breast injury in breaststroke. A common injury is knee injury, which is related to the breaststroke leg technique in breaststroke. The focus of the breaststroke licking leg is the movement of the licking leg. The difficulty is to turn the foot. It is necessary to emphasize the movement course and emphasize the movement rhythm. Most of the frog knee injury is caused by an action error. Focus: Quantitative analysis of landing technology. 2, backstroke and freestyle (climbing) The shoulder joint is the most common sports injury for backstroke and freestyle swimmers, which is what we often call swimming shoulders. The shoulder joint is the most active part of the human body. Because of its loose joint capsule and weak ligament, it has good flexibility, but its stability is relatively poor. Most athletes did not pay attention and timely treatment after the injury occurred and continued to repeat the injury action, and finally evolved into a shoulder shaft tear. Concerns: The injury of the shoulder joint occurs mostly in the winter training and the training season with more athletic training and more competitions. 3, butterfly stroke The strength of the waist in the butterfly stroke position is more important, so the athletes in the main stroke of the butterfly stroke are more likely to occur at the waist. Insufficient strength of the back muscles, uncoordinated waist during the swimming process, or improper arrangement of exercise or intensity, neglect of preparation activities or relaxation activities will cause a certain degree of waist damage. At the same time, the lumbar injury in the butterfly stroke project is positively correlated with the level of exercise and the number of years of exercise. (1) lumbosacral joint damage. The lumbosacral joint is the largest segment of the spine and even the trunk, and various causes of other injuries can also cause damage to the site. If there is an injury in the waist, it should be treated and recovered in time. If the back injury is not cured, training should not be continued to avoid injury to the circulation. (2) The back extensor muscle and the sacral spine muscle injury. In the butterfly training, the position and movement range of the body determine the effect of strokes on the limbs, while the body relies on the muscle strength of the muscles on both sides of the back and abdomen to maintain a dynamic balance to some extent. However, the muscle strength of the lumbar dorsal extension muscle composed of the short, scorpion-like sacral muscles distributed on each spine attachment is far less than that of the thicker ventral flexor muscles. Under the cause of the butterfly injury, it will inevitably This dynamic balance is destroyed, and the sacral muscle group is subjected to excessive load. As the amount of exercise or exercise intensity increases, the chance of injury to the muscle group increases. Based on the above introduction, I hope that the coaches can pay attention to the following points during the training: (1) Swimming is a cyclical project, try to avoid sports fatigue to ensure that the recovery effect can occur after the end of each competition recovery week. (2) Find timely treatment in a timely manner, strengthen communication with athletes, and pay more attention to their lives to find problems in time. (3) Strengthen comprehensive physical fitness training including flexibility and strength. (4) Strengthen technical training and develop four projects, and do not emphasize single project technology.
