Investigations of behavior and control of voluntary stereotyped rhythmic movement contribute to the enhancement of motor function and performance of disabled, sick, injured, healthy, and exercising humans. The present article presents examples of unprompted alteration of freely chosen movement rate during voluntary stereotyped rhythmic movements. The examples, in the form of both increases and decreases of movement rate, are taken from activities of cycling, finger tapping, and locomotion. It is described that, for example, strength training, changed power output, repeated bouts, and changed locomotion speed can elicit an unprompted alteration of freely chosen movement rate. The discussion of the examples is based on a tripartite interplay between descending drive, rhythm-generating spinal neural networks, and sensory feedback, as well as terminology from dynamic systems theory.

对随意刻板节奏运动的行为和控制的研究有助于增强残疾人、病人、受伤者、健康者和锻炼者的运动功能和表现。本文介绍了在自愿的刻板节奏运动中自发改变自由选择的运动速率的例子。这些示例以运动速率的增加和减少的形式出现，取自骑自行车、手指敲击和移动的活动。据描述，例如，力量训练、改变的功率输出、重复的较量和改变的运动速度可以引起自由选择的运动速率的自发改变。示例的讨论基于下降驱动、产生节律的脊髓神经网络和感觉反馈之间的三方相互作用，
