There are three degrees of muscle strain, with different degrees having different effects on sports. Muscle injuries are very common in competitive sports, such as some confrontational projects basketball, soccer, and some non-confrontational projects such as gymnastics, track and field projects. 3, degree of strain is a more serious situation, the muscle is completely stretched, the injured part can not move. The emergency treatment of muscle strain should follow the “RICE principle” When a muscle strain occurs, how should we deal with it in an emergency? There are 4 basic treatment measures that need to be paid attention to in the acute stage of muscle strain, which are referred to as “RICE principles”: “R” = “rest” rest. When a muscle strain occurs during exercise, the first thing to do is to stop the exercise and strengthen the rest. ”I” = “ice” ice. The best way to deal with a muscle strain during exercise in an emergency is to apply ice, because if there is bleeding when there is a muscle injury, using ice can make the blood vessels constrict to reduce bleeding and reduce tissue edema. ”C” = “compression” compression. In addition to ice, local compression can also reduce local bleeding and edema. ”E”=”elevation” Elevation. During recuperation, care should be taken to elevate the injured area so as to reduce local swelling.
