We analyzed changes in velocity and displacement variables of an Olympic snatch associated with practice. As technique of the snatch is learned via a training cycle, barbell velocity and barbell displacement are affected. A female beginning weightlifter was videotaped performing her first Olympic snatch and again after six weeks of training. Data, collected at 60Hz, was digitized and smoothed using Peak Motus software. The top of head, c7, manubrium, ear, shoulder, elbow, wrist, hip, knee, ankle, heel, toe, and the center of the bar of each frame were digitized. After the training period, the peak barbell velocity was significantly greater than before. Other notable changes were seen in completion time of the snatch and barbell displacement. Coaches and athletes can benefit by evaluating the changes in barbell displacement and velocity through training. By analyzing these variables coaches can better modify training programs to suit all levels of athletes.
