肌肉力量神经调控与停止训练的关系

背景：当运动员遇到疾病、受伤、旅行等情况时往往会停止训练,这对机体骨骼肌的神经调控的可能产生影响。目的：全面了解停止训练对机体肌肉力量神经调控能力的影响及其机制。方法：检索Medline数据库1983/2006收录的停止训练与肌肉力量神经调控的相关综述和论文报告,并根据检索到的文献中所列出的相关参考文献进行追溯查找。结果与结论：共纳入停止训练与肌肉力量神经调控的相关文献48篇。发现一定持续时间的停止训练可引起最大随意收缩力下降,但可能受到骨骼肌本身、脊髓及脊髓以上中枢的影响;同时,由于运动训练模式、肌肉收缩形式、测试部位、停止训练的状况等不同,可能会使最大随意收缩力及相关神经学适应在停止训练期间被不同程度地保留下来。

Relationship between training cessation and neural regulation of muscle strength

BACKGROUND:Training cessation usually occurs when athletes encounter certain circumstances, such as disease, injury or travel. This might affect the neural regulation of skeletal muscle. OBJECTIVE:To fully understand the effect of training cessation on muscle strength neural regulation ability and the mechanism behind it.METHODS:An online search of Medline database was performed for relevant reviews and research papers on training cessation and neural regulation of muscle strength published between 1983 and 2006. Then a tracing search was performed according to the references of the collected articles.RESULTS AND CONCLUSION:A total of 48 articles on training cessation and neural regulation of muscle strength were collected. The training cessation with certain duration can cause the decrease of maximal voluntary contraction, but this might be affected by spinal cord, nerve centre above the spinal cord and skeletal muscle itself. In the mean time, the maximal voluntary contraction and corresponding neural adaptation may retain to some extent during the training cessation, depending on the exercise training mode, the muscle contraction pattern, the testing position and circumstance during training cessation.
