(1) Maintain good physical condition. Through rehabilitation training, we can prevent muscle atrophy and contracture, improve the exercise ability of healthy limbs, maintain good cardiopulmonary function, and immediately put them into normal physical exercise once they recover.
(2) Prevent stop training syndrome. Various conditioned reflex connections established by individuals in long-term physical exercise may be destroyed once they suddenly stop exercising, resulting in serious functional disorders, such as neurasthenia, gastric dilatation, gastrointestinal dysfunction and so on.
(3) Proper rehabilitation exercise after injury can strengthen the stability of joints, improve the metabolism and nutrition of injured tissues, accelerate the healing of injury and promote the unity of function, morphology and structure.
(4) Through the rehabilitation training after injury, the energy metabolism of the body can be balanced, the weight gain can be prevented, and the time required to resume exercise after injury can be shortened.
