选取武术长拳类C级难度动作“旋风脚720°+马步”作为研究主体,采用高速摄影仪对“旋风脚720°+马步”动作的技术特征进行运动学时间特征的分析。结论如下:“旋风脚720°+马步”在时间参数上的特征表现为:运动员完成一次动作时,总时间平均为1.27 s,起跳阶段、腾空阶段、和着地阶段平均用时分别为0.35 s、0.72 s、0.20 s,腾空阶段的总时间最长,起跳阶段时间长于着地时间。在腾空阶段的上摆和夹伸保持两个阶段所用时间百分比明显长于夹伸阶段,两个阶段所用的时间百分比分别为41%和44%。说明“旋风脚720°+马步”起跳时间短,腿上摆速度快,夹伸动作迅速,可使空中姿态保持优美,完成高质量的击响动作。
Select the martial arts Changquan class C-degree difficulty action “Cyclone foot 720 + horse step ” as the main body of the study, the use of high-speed camera on the “Cyclone foot 720 ° + horse step,” the technical characteristics of kinematic time characteristics analysis. The conclusions are as follows: “Cyclone foot 720 ° + horse step ” in the time characteristics of the parameters showed that: the athletes completed an action, the total time of 1.27 s, take-off stage, vacated stage, and landing stage average time were 0.35 s, 0.72 s, 0.20 s, the longest total time of flight phase, the phase of take-off phase is longer than the ground time. The percentage of time spent holding both stages in the hovering phase was significantly longer than the pinch-out phase, with 41% and 44% of the time spent in both phases. Description “Cyclone foot 720 ° + horse step ” take-off time is short, fast legs swing speed, clip stretch action quickly, the air can maintain a beautiful gesture to complete high-quality ring action.
