运用文献资料法、数理统计法，遵循运动生物力学基本原理，对跳远助跑与起跳参与因素进行分析，旨在确定跳远运动员腾空过程上体顶端最高点定点标志，使运动技能与运动素质迅速而有效地合成，为高水平运动员技术训练的调控及科学化训练提供依据一结果显示：跳远成绩的理想程度有赖于人体形态、速度能力、踏板瞬间水平速度、起跳阶段相关动作力学特征、起跳离地瞬间水平速度、垂直速度、初速度、腾起角、空中动作合理性、落地时脚的触地点与重心抛射轨迹点差值等诸多因素的整体效应。
運用文獻資料法、數理統計法，遵循運動生物力學基本原理，對跳遠助跑與起跳參與因素進行分析，旨在確定跳遠運動員騰空過程上體頂耑最高點定點標誌，使運動技能與運動素質迅速而有效地閤成，為高水平運動員技術訓練的調控及科學化訓練提供依據一結果顯示：跳遠成績的理想程度有賴于人體形態、速度能力、踏闆瞬間水平速度、起跳階段相關動作力學特徵、起跳離地瞬間水平速度、垂直速度、初速度、騰起角、空中動作閤理性、落地時腳的觸地點與重心拋射軌跡點差值等諸多因素的整體效應。

Using literature and mathematical statistics method and following the basic principles of sport biomechanics of long jump run - up to participate in and take - off factors analysis, it aimed at identifying long jumpers vacated the top highest point of the process of fixed - point upper body, so the quality of sports skills and exercise promptly and efficiently, synthesis, high - level athletes for the regulation of technical training and provide the basis for scientific training. The results showed that the long jump score of the ideal body shape depends on the extent and speed capability, the level of pedal instantaneous speed, take - off stage of the mechanical characteristics of the relevant action, jump off the moment the level of speed, vertical speed, early speed and flight angle, air motion reasonable, when the feet touch the ground with the center of gravity locations projectile trajectory point margin, and the overall effect and many other factors.
