From: The generation of centripetal force when walking in a circle: insight from the distribution of ground reaction forces recorded by plantar insoles

Figure 2

Average (+ standard error, SE) of the vertical component of the ground reaction force (vGRF) normalized to body weight (% BW) measured during the linear trajectory (LIN) as the average of right and left foot values and during curved trajectory in the inner (Foot-In) and outer foot (Foot-Out). Values are obtained from the peak values of vGRF at heel strike (A) and toe off (C), and from the trough value at mid-stance (B). A. At Heel Strike, vGRF of both Foot-In and Foot-Out was lower than that of LIN foot. B. At Mid-Stance, both Foot-In and Foot-Out had greater vGRF values than LIN foot. C. At Toe Off, Foot-In had smaller vGRF values than LIN foot. *, p < 0.05; **, p < 0.005; ***, p < 0.0005.
