This study aimed to assess whether the benefits associated with stretch shorten cycle (SSC) movements required the movement frequency to be in resonance with the natural frequency of the elastic structures. Seventeen untrained participants performed SSC and concentric bench press throws. Further, quasi-static muscular actions were also performed in which a brief perturbation was applied to the bar with the resulting damped oscillations providing natural frequency data. It was observed that prior stretch did not facilitate concentric performance. Further, there were large significant differences between the natural frequency of the musculo-tendinous system and the frequency of the SSC movements. The authors hypothesize that the failure to achieve resonance contributed to the poor performance achieved in the SSC actions.
本研究旨在评估与拉长缩短周期（SSC）动作相关的益处是否要求动作频率与弹性结构的固有频率产生共振。17名未经训练的参与者进行了SSC和向心卧推投掷动作。此外，还进行了准静态肌肉动作，即对杠铃施加短暂扰动，由此产生的阻尼振荡提供固有频率数据。结果发现，预先拉伸并未促进向心动作表现。此外，肌肉肌腱系统的固有频率与SSC动作的频率之间存在显著差异。作者推测，未能实现共振是导致SSC动作表现不佳的原因。
