摘　　要：运用2块测力台和三维红外高速摄像系统进行同步测试,采集16名优秀男子拳击运动员在后手摆拳全力击打固定目标过程中,双脚地面支撑反作用力及运动学相关数据。双脚快速力量参数与出拳速度进行相关分析、曲线估计,并计算相应的回归方程。结果显示:前、后脚蹬地最大力量/体重、快速力量指数/体质量与出拳速度均呈显著正相关(P<0.01);蹬地达到最大力量峰值的时间与出拳速度呈曲线关系(P<0.01)。结论:(1)拳击运动员后手摆拳击打的过程中,双脚积极蹬地发力阶段快速发力对出拳速度均具有显著影响;(2)提高双脚积极蹬地发力阶段蹬地最大力量有助于提高后手摆拳出拳速度;(3)双脚积极蹬地发力阶段,一定范围内,缩短蹬地的发力时间有助于提高出拳速度;(4)提高双脚积极蹬地发力阶段发力速度有助于提高后手摆拳出拳速度;(5)后手摆拳下肢快速发力对出拳速度的影响,同肢体快速发力对自身动作速度的影响显示出趋于一致的规律。Three-dimensional video graphic and two KISTLER force-plate were used synchronized,and 16 male elite boxers performed back hook punch on Chinese Kung Fu testing engineering try their best.We collected the parameters of force-plate,kinematics parameters and speed of punch.Take a relative analysis,made a curve to estimate the relation between the parameters of speed strength and punch speed,and calculate the corresponding regression equation.Results： There are highest linear fitting degree between double feet maximum strength/weight,speed strength index/weight and punch speed,showed a linear positive correlation（P0.01）;and there is highest curve fitting degree between the time of reach maximum force peak and punch speed,showed a curvilinear relationship（P0.01）.Conclusions：（1）back hook punching,double feet fast drive force in active push-off phase has a significant impact on punching speed.（2）Enhance the double feet maximum force are very important to improve the speed of back hook punch in active push-off phase.（3）Shorten the time reach maximum force peak are promote to improve the speed of back hook punch in active push-off phase,within a certain range.（4）Improving the double feet the speed of drive force are very important to improve the speed of back hook punch in active push-off phase.（5）As a whole body multi-joint project,The effect of lower lamb fast drive force on punch speed in back hook punch has the same law as same limb fast drive force effect it＇s own movement speed.
