Much of the current research on sprint start has attempted to analyze the biomechanical characteristics of elite athletes to provide guidance on the training of sprint technique, with less attention paid to the effects of motor experience gained from long-term training on neuromuscular control characteristics. The present study attempted to investigate the effect of motor experience on the modular organization of the neuromuscular system during starting, based on he clarification of the characteristics of muscle synergies during starting. It was found that exercise experience did not promote an increase in the number of synergies but rather a more focused timing of the activation of each synergy, allowing athletes to quickly complete the postural transition from crouching to running during the starting.
目前的短跑起跑研究大多试图分析优秀运动员的生物力学特征，为短跑技术的训练提供指导，而较少关注长期训练获得的运动经验对神经肌肉控制特征的影响。本研究试图基于起跑过程中肌肉协同作用特征的阐明，探讨运动经验对神经肌肉系统模块化组织的影响。研究发现，运动经验并没有促进协同作用数量的增加，而是使每个协同作用的激活时间更加集中，使运动员能够在起跑过程中快速完成从蹲姿到跑步的姿势转换。
