Fig. 5. Mean peak ground reaction force (GRF) components (i, vertical; ii, fore–aft; iii, lateral) for normal curve sprinting (A, open symbols) and tethered curve sprinting (B, filled symbols) as a function of curve radius. Data for each condition from the outside leg (triangles) and the inside leg (inverted triangles) are given. Fore–aft GRFs indicate both peak braking GRFs (negative) and peak propulsive GRFs (positive). Mean peak GRFs (broken lines) and s.e.m. (gray bands) during straight path sprinting are given for each case. Values are means ± s.e.m. for the same number of subjects indicated for each condition as in Table 1.
