目的：确立弓步刺动作的速度构成特点及其决定性因素、花剑运动员弓步刺动作的协调性评定指标。方法：以国家男子花剑队12名一线优秀运动员为研究对象,使用高速红外摄像机及三维测力平台获取运动员做弓步刺动作过程中的运动学和动力学数据,对剑速曲线和重心速度曲线分析得出弓步刺动作的速度构成特点。对弓步刺动作的各项指标与剑速最大值做相关性分析,得到剑速最大值的决定性因素,并根据Hudson的协调性理论筛选出花剑运动员弓步刺动作的协调性评定指标。结果：原地弓步刺动作中剑速最大值与前腿膝、踝关节最大角速度和持剑臂肘关节最大角速度显著性相关。原地弓步刺动作重心速度与后腿膝踝关节的角速度最大值和平均角速度、前腿髋关节角速度最大值以及后腿蹬地力有显著性相关。结论：1）弓步刺动作的剑速最大值决定性因素是持剑臂肘关节的角速度。2）弓步刺动作中重心移动速度的决定性因素是后腿的快速蹬伸产生的地面水平方向反作用力和前腿的摆动速度。3）优秀花剑运动员的弓步刺动作具有良好的肘膝关节及前、后膝关节联动特征。

Objective：to determine the formations of speed and the critical factors of the lunge in fencing and to determine the evaluating indexes of balance in fencing athletes.Methods：12Chinese national fencing athletes are studied.The kinesiology and dynamics data of the lunge are acquired by using the high-speed infrared camera and three-dimensional force measuring plat.The formations of speed are determined by analyzing the weapon speed curve and body gravity speed curve.The formations of speed of the lunge are acquired by analyzing the individual index and the maximum speed of the weapon.The evaluating indexes of balance of the lunge are chosen by using Hudson＇s balance theory.Result：In the lunge,the maximal speed of the weapon and maximum angular velocity of knee、maximum angular velocity of ankle、maximum angular velocity of elbow were significantly correlated.In the lunge,body gravity moving speed and knee joint angular maximum and average velocity、ankle joint angular maximum and average velocity、maximum angular velocity of hip、the force which is generated by the opposite reaction between the floor and the leg extending were significantly correlated.Conclusions：1）In the lunge,the indexes determining maximal speed of the weapon are angular velocity of elbow.2）the determination of body gravity moving speed depends on the force which is generated by the opposite reaction between the floor and the leg extending and moving speed of the foreleg.3）the lunge is characterized by the mechanical linkage of the elbow and the keen.
