The purpose of this study was to investigate the influence of increasing load on the lifting characteristics of the parallel squat. Special attention was directed to the sticking point phenomenon. Specifically, the goal of this study was to determine the percentage of maximal load at which the sticking point first appears. Eight male powerlifters, of provincial and national calibre were recorded, via high-speed cinematography, while performing a single repetition of parallel squat at six levels of performance, in the following order: 50%, 60%, 70%, 80%, 90% and 100% of maximal load. The coordinates of five points: the fifth toe, the ankle, the knee, the hip, and the geometric center of the weights on the bar were collected on every frame throughout the movement. These data were subsequently used to determine the movement times, and to calculate desired angular displacements and velocities of body segments, and vertical velocity of the bar during each trial.
