Biomechanical Analysis of Weightlifting

Weightlifting is a sport who requires good strength and appropriate technique to make a weightlifter success in its lift. Weightlifting contains two main technique, which snatch and clean-jerk techniques. Both techniques have six phases, and the phases are, first pull; transition from first to second pull; second pull; turnover under the barbell; catching phase; rising from squat position. This book is about the biomechanical analysis on the weightlifting, and the result from the experiment will be compared with other researchers. The experiment is only for preliminary study in this thesis. The objectives for this experiment are to investigate the force exerted, observe the muscle activity and study the angle of joint on the subjects while lifting the barbell for both techniques. From the result shown by the subject and comparison with the professional athlete, the technique shown by the subject is not much different and give an almost same pattern. Analysis on weightlifting the practically as it can reduce the injuries and increase the performance of the lifter.
