Stepping Kinematics and Approach Speed Approach Speed The main effect of difficulty failed to reach significance, F (2, 74) = 2.968, p = 0.058, η p 2 = 0.074, but was significantly described by a linear polynomial trend ( p = 0.022, η p 2 = 0.134) with fastest approach speeds observed when faced with the target only ( M = 0.995 m/s) and slowest approach speeds observed when faced with two obstacles ( M = 0.969 m/s).
