摘要

本文调查了一组常规瑜伽练习者在进行单腿瑜伽姿势时，与健康对照组相比，是否表现出姿势控制差异。10名瑜伽练习者与10名非练习者组成的对照组进行了比较，他们进行了两种单腿支撑瑜伽姿势：Vrkasana（树姿势）和Natarajasana（舞者姿势）。使用避免使用水平力的遗传算法谱优化实现了压力轨迹中心的漫游和抖动分解，并用两足姿势数据进行了验证。此外，使用OpenSim从身体运动学中估计质心，并与随机输出进行比较。在Natarajasana期间，未观察到姿势控制适应。对于Vrkasana，瑜伽练习者显示出较低的压力中心椭圆置信区间区域、压力中心前后SD和较小的中外侧方向的散在SD，这表明可能与瑜伽训练相关的脊髓上前馈运动适应。

Postural Control Adaptations in Yoga Single-Leg Support Postures: Comparison Between Practitioners and Nonpractitioners.

This paper investigates whether a group of regular Yoga practitioners shows postural control differences compared with healthy controls while performing single-leg Yoga postures. Ten Yoga practitioners were compared with a control group of 10 nonpractitioners performing two single-leg support Yoga postures: Vrksasana (tree posture) and Natarajasana (dancer posture). Rambling and trembling decomposition of the center of pressure trajectories was implemented using a genetic algorithm spectral optimization that avoids using horizontal forces and was validated with bipedal posture data. Additionally, the center of mass was estimated from body kinematics using OpenSim and compared with the rambling outputs. During Natarajasana, no postural control adaptations were observed. For Vrksasana, the Yoga practitioners showed a lower center of pressure ellipse confidence interval area, center of pressure anteroposterior SD, and smaller rambling SD in the mediolateral direction, suggesting possible supraspinal feed-forward motor adaptations associated with Yoga training.

期刊介绍： Motor Control (MC), a peer-reviewed journal, provides a multidisciplinary examination of human movement across the lifespan. To keep you abreast of current developments in the field of motor control, it offers timely coverage of important topics, including issues related to motor disorders. This international journal publishes many types of research papers, from clinical experimental to modeling and theoretical studies. These papers come from such varied disciplines as biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. Motor Control, the official journal of the International Society of Motor Control, is designed to provide a multidisciplinary forum for the exchange of scientific information on the control of human movement across the lifespan, including issues related to motor disorders. Motor Control encourages submission of papers from a variety of disciplines including, but not limited to, biomechanics, kinesiology, neurophysiology, neuroscience, psychology, physical medicine, and rehabilitation. This peer-reviewed journal publishes a wide variety of types of research papers including clinical experimental, modeling, and theoretical studies. To be considered for publication, papers should clearly demonstrate a contribution to the understanding of control of movement. In addition to publishing research papers, Motor Control publishes review articles, quick communications, commentaries, target articles, and book reviews. When warranted, an entire issue may be devoted to a specific topic within the area of motor control.
