这一章提请注意可以应用于非稳态运动的基本原则，并强调了最近工作中出现的一般主题。人们可以考虑两大类“非稳态”行为：预期的、目标导向的速度（速度、方向）或身体高度的变化;以及在面对目标运动的扰动时保持目标运动的稳定反应。最近对非稳态运动的研究集中在两个主题上：最大加速度的限制，以及转向力学中的形态和行为因素。影响动物运动策略的因素包括：对环境知识的准确性和预测任何即将发生的地形变化的能力;运动目标;以及腿和身体与环境的内在机械相互作用。本章还强调了非稳定任务期间肢体内肌肉和关节协调的各个方面。
This chapter draws attention to basic principles that can be applied to non‐steady locomotion, and highlights general themes that have emerged from recent work. One can consider two broad categories of “non‐steady” behavior: anticipated, goal‐directed changes in velocity (speed, direction) or body height; and stabilizing responses to maintain a goal movement in the face of perturbations from it. Recent studies of non‐steady locomotion have focused on two themes: limits to maximal acceleration, and morphological and behavioral factors in turning mechanics. The factors that influence the animal's movement strategy include: accuracy of knowledge about the environment and ability to anticipate any upcoming changes in terrain; the movement goals; and the intrinsic mechanical interaction of the legs and body with the environment. The chapter also highlights aspects of muscle and joint coordination within the limb during non‐steady tasks.
