运用文献资料法和对比分析法,以国内外23名优秀男子跳远选手为研究对象,利用运动学参数对其全程技术特征进行比较分析,结果表明：国内选手助跑最后2步着板与离板瞬时水平速度、最后2步的步频提高率、垂直速度与腾起角均低于国外选手,而助跑的速度利用率、最后2步的步长变化、离地瞬间身体重心水平速度损失之和则明显高于国外选手。
運用文獻資料法和對比分析法,以國內外23名優秀男子跳遠選手為研究對象,利用運動學參數對其全程技術特徵進行比較分析,結果錶明：國內選手助跑最後2步著闆與離闆瞬時水平速度、最後2步的步頻提高率、垂直速度與騰起角均低于國外選手,而助跑的速度利用率、最後2步的步長變化、離地瞬間身體重心水平速度損失之和則明顯高于國外選手。

The article applies documents and comparative analysis to enhance men＇s long jump results in China.Taking the internal and external 23 elite athletes for subject,it makes use of kinematics parameters to analyze technical characteristics of the whole course.It has been shown that the final run-up domestic players step 2 from the plate with a plate of instantaneous speed,the final two-step cadence raise rates,vertical velocity and off angle of internal athletes are lower than that of foreign ones.Utilization of the speed and approach,the final two steps further changes from the moment physical level of focus and the loss rate of internal athletes are significantly higher than that of foreign ones.
