Physical activity provides the biologic stimulus for a number of body adaptive mechanisms and therefore is a potent force in both prevention and treatment of sports injury. It has been shown, however, that therapeutic exercise must be prescribed with precision and care if it is to be of optimal value. There are no "general" effects of exercise. The effects of exercise on the cellular structure of muscle, connective tissue, and the nervous system are specific to the intensity, duration, and frequency of exercise and dependent on the length of time after injury.
体育活动为许多身体适应机制提供生物刺激，因此在运动损伤的预防和治疗中都是一股强大的力量。然而，已经表明，如果要达到最佳效果，治疗性运动必须精确且谨慎地开具处方。运动没有“普遍”的效果。运动对肌肉、结缔组织和神经系统细胞结构的影响取决于运动的强度、持续时间和频率，并且取决于受伤后的时间长短。
