Fig. 3. Muscle activation levels across ankle position. Muscle activation levels (%MVIC) of the Gmax, VMO, VLO, and BF during isometric squats under three ankle positions: plantarflexion (–20°), neutral position (0°), and dorsiflexion (20°). *Significant differences between conditions are marked with p < 0.05. Error bars indicate standard deviations. %MVIC, percentages of maximum voluntary isometric contraction; Gmax, gluteus maximus; VMO, vastus medialis oblique; VLO, vastus lateralis oblique; BF, biceps femoris.
