Figure 1.

Comparison of vertical ground reaction force relative to body mass between low and normal strength groups at a standard speed of 0.8 m s⁻¹ (A) and at participants’ self-selected maximal speed (B). Solid line represents the mean response of those with normal knee extensor strength (> 1.5 Nm kg⁻¹) and dashed line represents the mean response of those with low knee extensor strength (< 1.5 Nm kg⁻¹). F1 = weight acceptance peak force, F3 = push-off peak force.
