    摘要:

    目的:选取瑜伽单腿支撑动作,对比专业组和非专业组下肢关节角度、关节力、肌力的生物力学特征,旨在为瑜伽初学者科学健身以及康复医师确定运动处方提供理论依据。方法:采用BTS红外动作捕捉系统采集运动学数据,Kistler测力台采集动力学数据,Anybody7.0 仿真软件计算下肢关节力和肌力,Biodex平衡测试系统评估单支撑稳定性。结果:(1)两动作中,下肢肌力均表现出专业组大于非专业组。树式支撑腿:胫骨前肌、臀中肌后束、髂肌内侧、缝匠肌肌力大于非专业组(P<0.05)。平衡腿:股二头肌短头、缝匠肌,梨状肌、下籽肌、髂肌外侧、髂肌内侧、臀大肌下束、闭孔内肌大于非专业组(P<0.05)。燕式平衡支撑腿:胫骨前肌、趾长伸肌、拇长伸肌、闭孔内肌、臀大肌上束大于非专业组(P<0.05)。平衡腿:拇长伸肌大于非专业组(P<0.05)。(2)PS-BI总体、前后方向、ASL总体、前后方向、左右方向的分数,专业组显著小于非专业组(P<0.05)。结论:关节角度的大小影响下肢肌肉练习的程度,在练习时应注意动作的规范和相应肌肉的锻炼。树式动作中,非专业组双腿肌力都与专业组存在显著差异,燕式平衡动作的差异更多地表现在支撑腿上。瑜伽练习能够多方位的提高单腿支撑稳定性。

    Abstract:

    Objective: The single leg support pose of yoga was selected to compare the biomechanical characteristics of lower limb joint angle, joint force and muscle force of professional and non-professional groups, so as to provide theoretical basis for scientific fitness of yoga beginners and exercise prescription determined by rehabilitation physicians.Methods: BTS infrared motion capture system was used to collect kinematic data, Kistler forceplate was used to collect dynamic data, Anybody 7.0 simulation software was used to calculate the joint force and muscle strength, Biodex balance system was used to evaluate the stability of single support. Results: (1) In both movements, the muscle force of lower limbs in the professional group was greater than the non-professional group. Support leg of Tree pose: The muscle strength of the tibialis anterior, gluteus medius posterior, iliac medialis and sartorius in the professional group was greater than the non-professional group (P<0.05). Balance leg: The muscle strength of the biceps femoris breve, sartorius, piriformis, gemellus inferior, iliac lateralis, iliac medialis, gluteus maximus inferior, obturator internus in the professional group was greater than the non-professional group (P<0.05). Support leg of Yan balabce: The muscle strength of tibialis anterior, extenso digitorum longus, extensor hallucis longus, obturator internus, gluteus maximus superior in the professional group was greater than the non-professional group (P<0.05). Balance leg: The muscle strength of extensor hallucis longus in the professional group was greater than the non-professional group(P<0.05). (2) The scores of professional group of front-rear, overall of PS-BI, overall, front-rear, left-right of ASL were significantly lower than the non-professional group(P<0.05). Conclusion: The size of joint angle affects the degree of muscle exercise of lower limbs. During the exercise, we should pay attention to the standard of movement and exercise the corresponding muscles. In the tree pose, the muscle strength of both legs in the non-professional group was significantly different in the professional group, and the difference in the Yan balance pose was more obvious on the supporting leg. Yoga exercises can improve the stability of one leg support in multiple directions.
