The result shows that the technical style of our athletes used is that stride length is shorter and stride frequency is larger,the buckjump time of our players is located at the floor level of the foul limit,the knee angel is unwind from touchdown on upright phase,in the sprint phase,the kneel angel is blurry from touchdown to upright phase,the uprightness displacement of body center and vertex are higher than the international athletes, this since stretching to leave a ground of opportune moment to be partial to early and making an effort action insufficiency with leg driving of the ankle joint relevantly, also with the leg put of front stretch is not enough active at the touchdown ground moment.

结果表明，我国运动员在后半程中，运用的是步长较短，步频较快的技术风格；腾空时间总体上处于犯规时限的下限，膝关节从着地瞬间直至垂直支撑面保持了可见的伸直状态，但在最后冲刺阶段，膝角出现了模糊伸直过程；身体重心垂直位移、头顶位置上下起伏均高于世界优秀运动员平均水平，这既与踝关节后蹬伸展离地时机偏早、用力动作不充分有关，也与着地瞬间摆动腿前摆后的前伸着地动作不够积极有关。
