Abstract

This study evaluated the kinetic differences between the traditional back squat (T-BS) and Smith machine back squat (SM-BS) performed at a variety of loads. Ten subjects were tested in six conditions including the T-BS and SM-BS each performed at 50%, 80%, and 100% of the subject’s five repetition maximum load on a force platform. The analysis of vertical ground reaction forces (GRF) revealed significant main effects for exercise load (p ≤ 0.001) but not for squat condition or the interaction of load and squat condition (p > 0.05). The analysis of sagittal plane GRF revealed significant main effects for exercise load (p ≤ 0.05), squat condition (p ≤ 0.001), and the interaction between load and condition (p ≤ 0.05). The analysis of frontal plane GRF revealed no main effects (p > 0.05). The SM-BS offers the user a resistance stimuli in the sagittal plane against which the exerciser can produce greater sagittal force.
