| 摘 要： | 跳远属于斜抛运动，根据斜抛运动远度公式S=V2sin2a／g可知，跳远的成绩与腾起初速度(V)和腾起角度有关于通过对中外优秀男子跳远运动员跳远技术的对比分析，发现我国男子跳远运动员提高成绩可以通过两种途径：一是提高绝对速度，同时适当降低助跑速度利用率，改进助跑最后几步的节奏，二是增大着板面和离地角，减少扇角，提高腾起角。

| Abstract: | The broad - jump belongs to the inclined throwing sport, according to formula S V2sin2a/ g, the score of the broad - jump rises with jumping inception speed( V) with the jumping angle concerning analysis to the technical contrast in broad - jump in athlete between Chinese and Foreign excellent man, it discovers our country man the broad - jump athlete increases the score can improve in two kinds of paths: While increasing absoluteness speed, adequacy lower the speed of helping the turn of speed to run at the same time, improves the rhythm of the last step, Another is to enlarge the Cape, reduce small Cape, increase the jumping rises Cape. |
