摘　　要：目的选取树式和燕式平衡两个瑜伽单腿支撑动作,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,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,Any Body 7.0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。结果树式和燕式平衡动作中,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)。树式平衡腿: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)。燕式平衡腿:拇长伸肌大于非专业组(P<0.05)。PS-BI总体、前后方向以及单腿站立(athlete single leg,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)。结论关节角度影响下肢肌肉练习的程度,在瑜珈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提高单腿支撑稳定性。Objective The single leg support tree pose and Yan balace of yoga was selected to compare the biomechanical characteristics of lower limb joint angles,joint force and muscle strength for professional and nonprofessional yoga practitioners,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,and Biodex balance system was used to evaluate the stability of single support.Results In both tree pose and Yan balance,the muscle strength of lower limbs in professional group was greater than that in non-professional group.Support leg of tree pose:the muscle strength of the tibialis anterior,gluteus medius posterior,iliac medialis and sartorius in professional group was greater than that in non-professional group(P<0.05).Balance leg of tree pose:the muscle strength of the biceps femoris breve,sartorius,piriformis,gemellus inferior,iliac lateralis,iliac medialis,gluteus maximus inferior,obturator internus in professional group was greater than that in non-professional group(P<0.05).Support leg of Yan balance:the muscle strength of tibialis anterior,extensor 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 of Yan balance:The muscle strength of extensor hallucis longus in professional group was greater than that in non-professional group(P<0.05).The scores of front-rear,overall of PS-BI,overall,front-rear,left-right of athlete single leg(ASL)in professional group were significantly lower than those in non-professional group(P<0.05).Conclusions The joint angle will affect the degree of muscle exercise in lower limbs.During yoga practice,attention should be paid to the standard of postures and the exe
