传统观点认为，运动过程（如姿态控制、步态等）中所产生的高变异性是与运动能力下降、病理学表现等相关联。但随着动态系统理论在运动科学领域的发展和深入，该观点受到了一定的挑战。近期的研究表明，研究运动中的变异性具有重要的理论意义和临床价值，并已成为应用动态系统方法研究人类运动稳定性的重要评价。本文回顾了动态系统理论及其方法在姿态控制和步态转换领域的应用，认为将非线性系统中变异性特征的研究方法引人到运动科学领域，并力求指导运动模式的形成和训练实践，可以为人们实现运动控制理念的更新、运动训练科学的转化，提供全新的思路和途径。此外，人体运动系统作为一个动态系统，分析和量化该系统协调运动模式中的变异性有助于理解变异性与稳定性之间的关系，并能为预防运动损伤和疾病临床诊断提供依据。

Greater variability is traditional viewed as associated with a decline of sport performance and pathologic problems during locomotion （such as impaired postural and gait control）. However, with the development of dynamic system theory in the field of movement science, the above-mentioned concept has been challenged. Recent studies suggested variability during movement was very important both theoretically and clinically. Variability had become an es- sential evaluation tool by using the dynamic system method to evaluate human movement stability. This paper reviewed the application of the dynamic system theory and method in postural control and gait transition studies. The analysis and quantification of the variability and stability in coordinated movement can 1 ） help researcher better understanding the relationship between the variability and stability; and 2） provide a theoretical basis for injury prevention and clini- cal diagnosis of pathological conditions.
