人体运动功能和肌肉损伤 北京体育大学 卢鼎厚 Human Motor Function and Muscle Injury Lu Ding-hou Beijing University of Physical Education ABSTRACT One spends one’s whole life in repeating habitual movements while maintaining postures appropriate to them. The delayed-onset muscle soreness induced by overloaded work is the result of disintegrative dominance, the aggravated disintegration and depolymerization of contractile proteins relative to their synthesis and polymerization, leading to alteration or disruption of contractile structure. After adequate rest and lessened work load, however, the synthetic metabolism may regain momentum, resulting in natural recovery of contractile structure and disappearance of the soreness. Yet, with the disintegrative dominance not relieved, repeated overloads would cause muscle injury, giving rise to relatively stable alteration unlikely to recover by itself. The method of oblique acupuncture at Ashi points inherited from traditional Chinese medicine has proved to be markedly effective for both acute and chronic muscle injuries by enhancing the assembly and synthesis of contractile proteins and promoting the restoration of muscle structure and function. Muscle injuries are a common and frequent complaint at home, in workplace and in sport grounds though they have never received the attention due. To assure the health of common people and to give full play to the part played by human resources in promoting economy and increasing production, it is important to assure adequate rest in work days and to make keep-fit exercises an essential part of the life of each community member. It is thus also important to open courses on pathogenesis, treatment and prevention of muscle injuries in medical and sports colleges, to establish in hospitals clinics specialized in muscle injuries, to conduct researches in colleges and institutes related to medicine, sports and education, and to propagate scientific knowledge about muscle injury.
