Abstract:
The purpose of this study was to measure and analyze kinematic differences between competitive collegiate (CLG, n = 9) powerlifters, competitive high school (HS, n = 9) powerlifters, and novice (NV, n = 11) powerlifters during a maximal squat to determine the effect of skill level on performance. All powerlifters performed 3 squats, with the final squat being their 1 repetition maximum. Kinematic data (descent, ascent, total lift times, knee angle magnitude, knee angular velocity, and knee angular acceleration) was measured using 2-dimensional motion analysis equipment. Differences in mean peak kinematic values between the 3 groups were analyzed using a 1-way multivariate analysis of variance, p
