Abstract

The purpose of this study was to investigate the effect of load on trunk and knee coordination during different phases of the snatch. Four elite weightlifters performed the snatch from submaximal to maximal loads (~85-100%), while video data were collected with eight cameras. The video data were processed with markerless motion capture software, and trunk and knee joint angles were calculated. Trunk-knee coupling angles were calculated via vector coding analysis. During the pull phase, an increase in the frequency count of trunk-knee coordination patterns in response to an increase in load, indicated that the pull phase lengthened as the loads increased. Each weightlifter, however, made load-specific adjustments in their trunk-knee coordination pattern across the different phases, which may suggest the need for individualized technique training.
