摘　　要：目的:以寸拳为例,从动力学和运动学的角度剖析武术"击打"动作中"二次发力"现象,为研究击打提供理论支撑。方法:20名自愿者分成对照组(普通大学生)和实验组(咏春拳练习者),用高速成像捕捉仪及搏击项群测试仪测试关节角度、速度、加速度、时间及力量等指标。结果:踝、膝、髋、肩、肘关节角度迅速变化时间点,对照组左侧0.25、0.20、0.30、0.35、0.40s;右侧0.20、0.20、0.20、0.30、0.30s,右侧踝、膝、髋与肩、肘出现0.10s的间隔,出现"相互抵消"作用。实验组左侧0.35、0.25、0.35、0.30、0.35s;右侧0.25、0.30、0.30、0.30、0.30,出现高度一致性,产生"累计效应"。实验组五项指标显著高于对照组,P<0.01、P<0.001。对照组最大速度和最大加速度出现时间分别为0.421±0.176s、0.424±0.124s,时差0.003s,P>0.05;实验组分别为0.376±0.105s、0.333±0.103s,时差0.043s,P<0.001,最大加速度先于最大速度出现。结论:协调性(神经支配肌肉)和打击时机(动量和冲量关系)是武术"击打"动作中的"二次发力"现象的根源。Objective： In order to provide theoretical support for boxing by analyzing from the viewpoint of dynamics and kine- matics and the analysis of martial arts and secondary aetion power phenomenon. Methods：20 volunteers were divided into con- trol group （ normal college students） and experimental group （ wing ehun practitioners）, using high - speed image capturing apparatus and fight XiangQun tester test joint Angle, speed, acceleration, time and strength index. Results ： the ankle, knee, hip, shoulder, elbow Angle rapidly changing point in time, the control group on the left side of the 0.25,0.20,0.30,0.20,0. 30s;On the right side of 0.20,0.20, 0.20,0.20,0.20s,the right side of the ankle, knee, hip and shoulder, elbow, the inter- val of 0.10s ,appear ＂offset＂. The experimental group on the left side of the 0. 35 ,0. 25 ,0. 35 ,0. 25 ,0. 35s ;On the right side of 0. 25,0. 30,0. 30,0. 30,0. 30 ,high consistency, produce the ＂cumulative effect＂. Experimental group five index is signifi- cantly higher than the control group, P 〈0.01, P 〈 0.001. Control group maximum velocity and maximum acceleration time were 0.421±0. 176s, 0.424 ±0. 124s, time of 0.003s,P 〉0.05;The experimental group were 0.376±0. 105s, 0. 333±0. 103s, time of 0. 043s, P 〈 0. 001, the maximum acceleration prior to maximum speed. Conclusion： coordination （ innervation muscles） and the fight against the timing （momentum and impulse） is a martial arts and action of the source of power is sec- ondary phenomenon.
