Abstract

The purpose of the study was to analyze the
kinematical differences between the first and the second pull of the snatch
technique in elite male weightlifters. The heaviest successful snatch lifts of
seven male weightlifters who won gold medals at the 2010 Men’s World
Weightlifting Championship were analyzed. The snatch lifts were recorded using
2 S-VHS cameras (50 fields/s), and points on the body and the barbell were
manually digitized using the Ariel Performance Analysis System. The results
revealed that the maximum vertical velocity of the barbell was significantly
greater in the second pull than that of the first pull (p<0.05). While the
mechanical work produced in the first pull was significantly greater, the power
output was significantly greater in the second pull (p<0.05). As a result, it was revealed that the
second pull phase was faster and more powerful than the first pull, and that the
kinematics of the barbell during the second pull had a decisive role for a
successful lift.
