Mechanical investigation of ball-ground impact under high and low speed

Abstract

Football collision is a common phenomenon during football matches, but mechanical approach to study football collision process was quite limited. This study was using force platform and high speed video system to monitor the football collision under low and high speed conditions. The high speed collision was nearly double compared the speed of low collision. But the contact time under these two collision conditions was not discrepancy a lot. We found when the speed increasing, the collision power will increase a lot. Therefore, in the football match, especially the player shots or rescues dangerous ball, if the ball hit directly on one part of human body, it may produce harm to the body even damage. We should do some buffering action to minimize the impact and protect our body. Some meaningful value in this study, were very helpful to football training and relating product development, providing certain theoretical guidance and improve the development of the football sport.
