The catchlike property of skeletal muscle is the force augmentation produced by the inclusion of an initial, brief, high-frequency burst of two to four pulses at the start of a subtetanic low-frequency stimulation train. Catchlike-inducing trains take advantage of the catchlike property of skeletal muscle and augment muscle performance compared with constant-frequency trains, especially in the fatigued state. Literature spanning more than 30 years has provided comprehensive information about the catchlike property of skeletal muscle. The pattern of the catchlike-inducing train that maximizes muscle performance is fairly similar across different muscles of different species and under various stimulation conditions. This review summarizes the mechanisms of the catchlike property, factors affecting force augmentation, techniques used to identify patterns of catchlike-inducing trains that maximize muscle performance, and potential clinical applications to provide a historical and current perspective of our understanding of the catchlike property.
骨骼肌的强直态增强特性是指在低于强直刺激频率的低频刺激序列开始时，加入两到四个脉冲的初始短暂高频爆发所产生的力增强现象。诱导强直态增强的刺激序列利用了骨骼肌的强直态增强特性，与恒频刺激序列相比，能增强肌肉性能，尤其是在疲劳状态下。超过30年的文献提供了有关骨骼肌强直态增强特性的全面信息。在不同物种的不同肌肉以及各种刺激条件下，使肌肉性能最大化的诱导强直态增强刺激序列模式相当相似。本综述总结了强直态增强特性的机制、影响力增强的因素、用于识别使肌肉性能最大化的诱导强直态增强刺激序列模式的技术以及潜在的临床应用，以提供我们对强直态增强特性理解的历史和当前视角。
