Abstract

The main question of the present study was whether the use of ordinary shoes and weightlifting shoes is effective in changing oscillation of the center of foot pressure (COP) in professional weightlifters during the performance of squat movement. 20 professional male weightlifters used the barbell to perform Squat in three condition, once with barefoot, with ordinary shoes and with a weightlifting shoe on a foot pressure tool, with the aim of scanning the foot plantar segment and examining oscillation of the center of pressure in foot. In order to analyze the data, the map and the oscillation parameters of the plantar pressure center of each athlete in three condition were extracted from the pressure foot device. COP path line and its Ellipsoidal area were investigated. The results showed that the use of ordinary shoes and weightlifting shoes has a significant effect on the two variables of path line and ellipsoidal area of COP and increases balance in weightlifters during squats significantly The use of weightlifting shoes while performing important and fundamental squats in weightlifters, increases balance and is recommended to athletes and coaches to consider the use of these sports tools to prevent injury and improve their performance.
