Research on the Mechanics Principle of 100-Meter Running

Abstract

Fascinated by “superpowers” all over time, people are increasingly attracted by speed, a form of superpowers, which can be seen from the “flash” in movies or “locomotive” in American TV series. Given such obsession with the pursuit of speed, this paper selects the 100-meter race that reflects the speed of human beings as the research topic. This research analyzes the most basic movement of humans, that is, running. Firstly, with humans regarded as particles, 100-meter running is divided into stages of start, acceleration, maintenance, and sprint in this paper. By analyzing the speed, acceleration, reaction time, stride length, stride frequency, and other indicators of top athletes represented by Bolt in different stages, MATLAB simulation is conducted for comparison and summary. Secondly, with humans regarded as non-particles for analysis, simulation research is implemented on the landing mode of feet, the force exertion mode of arms, and some leg muscles combined with torque. Finally, this paper carried out experiments to understand the laws of particle motion mechanics in 100-meter running as well as figure out how various stride frequencies and arm swings affect running speed, in addition to analyzing the influence of resistance on running posture. Theoretically and experimentally exploring the principles of running mechanics, this paper initiates a detailed discussion of the influencing factors and their improvement from an innovative perspective, so as to put forward suggestions for teenagers to optimize their running performance.
