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.
对自愿刻板的有节奏运动的行为和控制的研究有助于提高残疾、患病、受伤、健康和锻炼人群的运动功能和表现。本文介绍了在自愿刻板的有节奏运动中自由选择的运动速度发生自发变化的例子。这些例子以运动速度增加和减少的形式，取自骑自行车、手指敲击和运动的活动。例如，力量训练、改变输出功率、重复运动和改变运动速度可以引起自由选择的运动速度的自发变化。对这些例子的讨论基于下行驱动、产生节奏的脊髓神经网络和感觉反馈之间的三分相互作用，以及动态系统理论的术语。
