The purpose of this investigation was to determine the effect of involvement in power lifting, Olympic lifting, and sprinting on strength and power characteristics in the squat movement. A standard one repetition maximum squat test, jump squat tests, and vertical jumps with various loads were performed. The power lifters (PL, n = 8), Olympic lifters (OL, n = 6), and sprinters (S, n = 6) were significantly stronger than the controls (C, n = 8) (p <= 0.05). In addition, the OL group was significantly stronger than the S group. The OL group produced significantly higher peak forces, power outputs, velocities, and jump heights in comparison to the PL and C groups for jump trials at various loads. The S group produced higher peak velocities and jump heights in comparison to the PL and C groups for jump trials at various loads. The PL group was significantly higher in peak force and peak power for jump trials at various loads in comparison to the C group. The data indicates that strength and power characteristics are specific to each group and are most likely influenced by the various training protocols utilized.
