跳遠與三級跳遠是跳部運動中相當受人矚目的項目，三級跳遠包含三次著地與起跳，而 跳遠則僅有一次著地與起跳，二種運動在動作表現上基本而言非常相似，尤其三級跳遠最後 一步雙腳跳躍更是相同於跳遠，早期在成績表現有趨於兼項的參與，但隨著專項性技術發展 ，二者在技術層次上趨於專精, 所以本文主要目的即依據運動生物力學的觀點探討跳遠和三級 跳遠之間的差異提供教練、選手之參考，提昇技術表現。

　　　　　Both Long Jump and Triple Jump are people's focuses in jumping sports. Triple Jump involved three landing and take off, but Long Jump only contain one landing and taking off. Basically, these two sports are very similar in motion expression, especially the last step jump in Triple Jump is just like a Long Jump. In the early stage, athletes of these two events were always concurrent in participation. However, along with the development of individual event technique, each of these sports tends to specialize in technical level. Therefore, the purpose of this monograph is to discuss the discrepancies between Long Jump and Triple Jump based on the viewpoint of biomechanics. Coaches and athletes can make reference to it.
