Sports on campus are an important part of quality education. Sports can make us have a stronger body, but they can also bring side effects – sports injuries. They are at the stage of growth and development, their bones and joints and other organs are not fully developed, muscle strength is still weak, poor neural coordination, unstable technical movements, psychological immaturity, lack of self-protection awareness, etc., coupled with the intensity of sports and lack of warm-up, protection and other reasons more likely to occur sports injuries. The highest probability of student sports injuries is soft tissue contusions and skin abrasions, followed by ligament and muscle strains, sprains, fractures and dislocations, and other injuries. Sports injuries are closely related to the type of sport. How to avoid sports injuries in daily sports? How to handle sports injuries properly after they occur? Is a common concern of many parents and students. 1, running Because of the simple technical requirements, without special venues, clothing and equipment, whether on the sports field or road, or even between the fields, can be running exercise. Because of the popularity, is also one of the most common sports that lead to injury. Mainly in running is accidental fall resulting in skin abrasions, muscle soft tissue contusions, fractures, joint ligaments, tendons, cartilage injuries, etc.; running on uneven ground is also very easy to occur joint sprains, such as ankle sprains; In addition, the lower limbs as the main motor unit of running, its joints in constant high-intensity movement with the corresponding muscle groups and the impact of ground reaction force is also very easy to damage, such as muscle spasms In addition, the joints of the lower limbs, as the main sports unit of running, are prone to injuries such as muscle spasm, strain, bone marrow edema of the tibial plateau caused by long-distance running, tibial periostitis, fatigue fractures (tibia, metatarsus, etc.) and plantar fasciitis. Especially in recent years the popularity of marathon sports seems to have become a fashion, and the author often encountered young students lack of systematic training, occasionally after participating in the race led to bone marrow edema and even fatigue fractures. 2, jumping sports (high jump, long jump, box jump, etc.) This type of sports injury is most likely to occur in the jump and landing two moments. When jumping, the foot is subjected to instantaneous ground seizure force of more than 20 times body weight, which can easily lead to plantar fasciitis, and flat-footed patients are more likely to have acquired posterior tibial tendon insufficiency and aggravated arch collapse. In addition, the impact force is transmitted to the lumbar spine easy to lead to lumbar back muscle strain, and even lumbar spine tension fractures. While landing is prone to ankle sprains, knee injuries, etc. Box jumping is an important project for girls in physical education, is also the hardest hit by sports injuries among girls, and the technical difficulty of the psychological fear, heavy weight load, inadequate preparatory activities, technical movements out of shape, the intensity of the movement more than their own ability to bear. In addition to the physiological characteristics of girls themselves, injuries often occur when leaping and landing, commonly ankle sprains, knee meniscus injuries, ligament injuries, patellar dislocation, etc. 3, soccer Football is the world’s number one sport, many boys are hardcore fans, the pursuit of strength and skill in soccer, playing a game requires the mobilization of all our major joints, so in soccer is more prone to a variety of sports injuries, and therefore is one of the highest incidence of sports injuries. Compared to ordinary running sports, soccer has a significant increase in the number of sharp stops and directional movements, and frequent twisting and ramming puts joint ligaments, meniscus and other tissues to a great test. In addition to the common bruises and contusions, ankle sprains are the most common injuries. This is followed by muscle strains and contusions in the front and back of the thigh. Knee injuries are the next most common. Although meniscal tears, knee ligament injuries, patellar fractures, and chondromalacia patellae are relatively uncommon, they are more difficult to treat once they occur. In particular, the anterior cruciate ligament is a very important ligament in maintaining the stability of the knee joint, mainly controlling tibial anterior translation and internal rotation. In soccer, a sharp stop and turn and a rapid twisting of the knee usually causes a huge tension load on the ACL, and the ligament is easily torn or even completely ruptured in the process. 4, basketball On the level of intensity, basketball than soccer, so the basketball court is also a high incidence of sports injuries. In basketball, sharp stops and directional movements are more frequent, and knee collisions often occur when passing people with the ball, as well as ankle sprains and ligament or meniscus injuries to the knee when jumping to the ground and stepping on other players’ feet. In particular, the ACL is a “very injured” tissue in basketball. Basketball injuries account for nearly 1/2 of the ACL injury surgeries performed each year at Changhai Hospital, and the percentage of basketball injuries among adolescent patients is even higher. In addition, when shooting, laying up, grabbing rebounds and dunking, the shoulder joint is often in an extreme forward flexion and supination position when completing these actions. Friends who like to be cool like to hang on the basket for a while after dunking, which is also very likely to cause shoulder dislocation. 5, volleyball Repeated jumping and landing on the spine, knee, ankle joint impact, easy to lead to lumbar disc herniation, patellar chondromalacia, ankle sprain, etc.; and shoulder joint in volleyball because often extreme abduction external rotation force buckle is also prone to injury, good injury shoulder dislocation, rotator cuff injury, biceps tendon injury, etc.; in addition, the wrist in the fall to save the ball is prone to navicular fracture. Interphalangeal joint sprains or dislocations are easy to occur when blocking the net. 6, table tennis, badminton, tennis After talking about the big ball sports, we can not ignore the small ball sports. Table tennis, badminton and the gradually popular tennis, are popular small ball sports. These sports have certain requirements for upper limb strength skills, and thus the incidence of upper limb sports injuries is higher, such as vigorous snapping, hitting the ball will make the shoulder joint, the muscles around the elbow joint are subject to a huge tension load, easily caused by rotator cuff injuries, tennis elbow and other strain injuries. The field of small ball sports is usually relatively flat, although not easy to occur ankle sprain, but repeated changes of direction will bring enormous pressure on the meniscus, easy to cause meniscus injury. 7, swimming Compared with land-based projects, swimming has good protection for the lower limbs and spine, but the shoulder joint is the most easily damaged joint in swimming projects, accounting for 90% of the proportion. Freestyle, backstroke and butterfly are three strokes that mainly rely on the contraction of the shoulder joint inward and internal rotation muscles. The extreme upward and internal rotation of the shoulder joint can easily lead to rotator cuff injury (also known as swimming shoulder), acromion impingement syndrome and biceps tendonitis. Through the above explanation we can easily see that although the pain of sports injuries will be relieved quickly, the damage to joint cartilage, ligaments and other structures is very difficult to be detected in the first place. Therefore, we hope that we can strengthen our awareness of sports protection, and once the injury has occurred, we should ask a professional sports medicine doctor to assess the condition and develop a scientific rehabilitation and treatment plan, so that we can get a better post-injury rehabilitation and return to the sports field with more confidence in the future.
