This study investigated relationships between load weight and muscular power in different squat movement by analyzing ground reaction force. Thirteen track and field athletes performed two kinds of squat movement (non-rebound squat and rebound squat). The squat movement used five types of loads depending on body weight (100%BW, 150%BW, 200%Vw, 250%BW, 300%BW). The ground reaction force was measured with force plate and analyzed maximum force, standup-time, maximum force / second. Increase of the maximum force was not proportionate to load, rate of increase was decreasing as the load was increased. When style of squat movement changed from non-rebound squat to rebound squat, the muscular power which was actually demonstrated in case of equal load differed greatly. These results suggested that not only lifting load but also style of motion and acceleration during movement were important in order to perform effective muscular power training and measurement.
