Abstract
High impact forces experienced during landing has been associated with an increased risk of injury. Hence the concept of cushioning has been proposed in sports flooring and shoe manufacturing to reduce impacts and prevent injuries. This study investigated the influence of different sports floorings as well as sports shoes on impact forces and jump performance during different jump tasks. Twenty-one active adults performed multi-jump and ankle jumps on force plates. These tasks were repeated with minimalist and cushioned shoes on different sports floorings with varied shock absorption properties. Our main findings showed that peak vertical ground reaction force did not differ among the different sports floorings. However, lower vertical instantaneous loading rate was found on the flooring with the highest shock absorption properties when compared with those with lower shock absorption properties. Moreover, a global shoe effect was found on vertical instantaneous loading rate and peak vertical ground reaction force. No sports flooring effect was detected for jump height. One should be able to determine the shock absorption properties which reduce impact force without affecting jump performance.
