The aim of this study was to determine the effects of Chinese martial arts practice on postural reaction control after perturbation. Participants standing in Romberg tandem posture were subjected to an unexpected lateral platform translation with the eyes open or closed at two translation amplitudes. The peak displacement of the centre of pressure and of the centre of mass, and the onset latency of muscular activity (tibialis anterior, gastrocnemius, lumbodorsal muscular group, and rectus abdominis), were evaluated for martial arts practitioners and for sport and non-sport participants. Compared with the sport and non-sport participants, the martial arts group showed lower maximal centre of pressure and centre of mass peak displacements in both the lateral and anterior - posterior directions, but no difference was found in the onset of muscular responses. We conclude that martial arts practice influences postural reaction control during a fixed-support strategy in a tandem task. The martial arts group used the ankle joint more frequently than the sport and non-sport participants, especially in the eyes-closed conditions. Our results suggest that the better balance recovery in the martial arts group is a consequence of better control of biomechanical properties of the lower limbs (e.g. through muscular response by co-contraction), not a change in the neuromuscular temporal pattern.
本研究的目的是确定练习中国武术对受扰动后姿势反应控制的影响。让站在Romberg串联姿势的参与者在睁眼或闭眼状态下,以两种平移幅度接受意外的侧向平台平移。对武术练习者、从事体育运动者和非体育运动参与者,评估其压力中心和质心的峰值位移,以及肌肉活动(胫前肌、腓肠肌、腰背肌群和腹直肌)的起始潜伏期。与从事体育运动者和非体育运动参与者相比,武术组在侧向和前后方向上的最大压力中心和质心峰值位移较低,但在肌肉反应起始方面未发现差异。我们得出结论,练习武术会影响串联任务中固定支撑策略期间的姿势反应控制。与从事体育运动者和非体育运动参与者相比,武术组更频繁地使用踝关节,尤其是在闭眼条件下。我们的结果表明,武术组更好的平衡恢复是更好地控制下肢生物力学特性(例如通过共同收缩产生肌肉反应)的结果,而不是神经肌肉时间模式的改变。
