It can prevent muscle atrophy, strengthen joint stability, accelerate blood circulation, improve the metabolism and nutrition of injured tissues, eliminate adhesions, stimulate growth, shorten repair time, and also enable the injured part to get proper rest. Athletes should try to avoid completely stopping training after injury.
