被认为影响人的速度的因素是较短的地面接触时间,较低的步幅频率,较长的挥动时间,较大的步幅角和较长的步幅。特别是,冲刺跑步者通过施加更大质量特定的地面力,特别是水平踝速度,接触时间和步速,使其加速度和最大冲刺速度最大化。在考虑速度时,体育研究人员还会考察长跑运动员,比赛距离在5-42公里(3-26英里)之间。这些跑步者中最快的是使用相当大的足底压力 – 足部施加在地面上的压力 – 以及生物力学参数的变化,随着时间和空间测量的腿部运动。马拉松比赛中跑得最快的一组(如短跑运动员)是年龄在25-29岁之间的男子。根据2012至2016年间芝加哥和纽约的马拉松比赛,这些男性的平均速度在每分钟170-176米之间。因为纽约市的马拉松比赛在波浪中运行 – 也就是说,有四组跑步者谁以约30分钟的间隔开始比赛 – 在整个比赛中5公里段的跑步者速度统计数据。 Lin及其同事利用这些数据为这一概念提供了支持速度的一个因素是竞赛选手在比赛结束时更频繁地提高速度和改变位置。

Factors that are considered to affect human speed are shorter ground contact times, lower stride frequencies, longer swing times, larger stride angles, and longer strides. In particular, sprint runners maximize their acceleration and maximum sprint speed by applying greater mass specific ground forces, particularly horizontal yaw speed, contact time and pace. When considering speed, sports researchers also look at long-distance runners, which are between 5 and 42 kilometers (3-26 miles). The fastest of these runners is the use of considerable foot pressure – the pressure exerted on the ground by the foot – as well as changes in biomechanical parameters, measuring leg movement over time and space. The fastest group in a marathon (such as a sprinter) is a man between the ages of 25-29. According to the marathon in Chicago and New York between 2012 and 2016, the average speed of these men is between 170-176 meters per minute. Because the New York City marathon runs in the waves – that is, there are four groups of runners who start the game at about 30 minute intervals – runners speed statistics for the 5km segment throughout the game. One factor Lin and his colleagues used to use this data to support the concept was that contestants increased their speed and position more frequently at the end of the game.
