Abstract

A new analysis, based on the equations of motion, is made of the influence of aerodynamic drag on the trajectory and aerial range achieved by a long jumper. The general result is applied to a particular case, namely the world long jump record obtained by Bob Beamon at the Mexico Olympics in 1968. Calculations are also made of the influence of body height and jumping technique on overall long-jump performance. A comparison is made between the relative importance of aerodynamic and anthropometric aspects of long jump performance.

摘要

基于运动方程进行了一项新的分析，研究空气阻力对跳远运动员的轨迹和空中距离的影响。将一般结果应用于一个特定案例，即鲍勃·比蒙在1968年墨西哥奥运会上创造的世界跳远纪录。还计算了身高和跳跃技术对整体跳远成绩的影响。对跳远成绩中空气动力学和人体测量学方面的相对重要性进行了比较。
