这篇简短的综述集中于前臂屈肌的最大力量偏心动作后肌肉功能变化的时间进程和其他与肌肉损伤相关的因素。本文提供了109名受试者的数据，以描述这些变化的准确时间进程，并试图建立这些指标之间的关系。疼痛高峰出现在运动后2~3d，肿胀高峰出现在运动后5d。最大力量和完全屈臂能力在运动后即刻下降最大，在接下来的10d内呈线性恢复。血肌酸激酶(CK)水平在运动后2d急剧上升，这也是自发性肌肉缩短最明显的时候。其中一些反应的时间进程的相似性是否意味着它们是由类似的因素造成的，这一点还有待确定。一轮偏心运动的表现会产生一种适应，使肌肉对随后一轮运动造成的损伤更具抵抗力。适应的长度在不同的措施中是不同的，当训练方案间隔6wk时，与第一轮相比，所有措施在第二轮时的反应都有所减少。在10wk后，只有CK和肌肉缩短表现出反应的减少。6个月后仅CK反应降低。细胞因素和神经因素的结合可能参与了适应过程。
This brief review focuses on the time course of changes in muscle function and other correlates of muscle damage following maximal effort eccentric actions of the forearm flexor muscles. Data on 109 subjects are presented to describe an accurate time course of these changes and attempt to establish relationships among the measures. Peak soreness is experienced 2-3 d postexercise while peak swelling occurs 5 d postexercise. Maximal strength and the ability to fully flex the arm show the greatest decrements immediately after exercise with a linear restoration of these functions over the next 10 d. Blood creatine kinase (CK) levels increase precipitously at 2 d after exercise which is also the time when spontaneous muscle shortening is most pronounced. Whether the similarity in the time courses of some of these responses implies that they are caused by similar factors remains to be determined. Performance of one bout of eccentric exercise produces an adaptation such that the muscle is more resistant to damage from a subsequent bout of exercise. The length of the adaptation differs among the measures such that when the exercise regimens are separated by 6 wk, all measures show a reduction in response on the second, compared with the first, bout. After 10 wk, only CK and muscle shortening show a reduction in response. After 6 months only the CK response is reduced. A combination of cellular factors and neurological factors may be involved in the adaptation process.
