Mean peak torque values (Nm, black dots) for each angle-velocity combination with respective modeled 3D strength surfaces for (a) female DF, (b) female PF, (c) adjusted female PF (i.e., without 2 isometric angles, 0° and −10°, that may have included torque from knee and hip extension moments), (d) male DF, (e) male PF; and (f) adjusted male PF (i.e., without 2 isometric angles, 0° and −10°, that may have included torque from knee and hip extension moments)
