Time-Motion analysis of the 2017 Wrestling World Championships

Abstract

Background and study aim. The purpose of this study was to determine the relative contribution of energy systems in a freestyle (FS) and a Greco-Roman (GR) wrestling match, quantity and quality of obtained scores, and the competition efficiency of winners in the 2017 Wrestling World Championships (WCh) through analysing the recorded videos of all the matches of this event. Material and method. The materials of the present study were 295 FS and 266 GR recorded videos of the 2017 WCh, a multimedia player (lap top) for watching and analysing them, and a chronometer for recording the different duration of activities happening during these matches. In addition, special papers were designed in advance to make sure that all the required data were recorded properly. Result. The percentages of ATP-PC (ATP), lactic (LAC), and aerobic (AERO) energy systems were 6.66, 62.74, and 30.60 in FS, and 5.94, 67.53, and 26.53 in GR. Quantity and quality analysis of scores showed that FS wrestlers significantly scored more 1- and 4-point, while GR wrestlers were superior regarding the quality 2-point. The average competition efficiency of gold medallists was 18/43±4/67 in FS and 15/87±3/18 in GR which were statistically significantly greater than that of all other placers. Conclusion. This study showed the dominance of LAC in a wrestling match in both styles, although their relative contribution was significantly different between styles. In addition, FS wrestlers significantly scored more points, and Gold medallists demonstrated the greatest average competition efficiency compared to other medallists.
