During the performance of a squat, several authors have recom- mended various positions for place- ment of the foot (4.10,12,15,16). The multiple regression model indicated that ankle dorsiflexion with a flexed knee and the hip flexion ROM were significantly associated with squat depth in male subjects (R 2 = 0.435) and ankle dorsiflexion with an extended knee and dorsiflexor strength were significantly associated with squat depth in female subjects (R 2 = 0.324).

Hey AC Community! Now for a paradox: If a guy has a long history of lifting with some flexion, the trabecular bone in the vertebral body will be strongly adapted. Knee flexion angle was statistically greater in NARROW than WIDE (P < 0.0001, d = 2.56‐2.86); no statistical differences were observed for hip flexion angle between conditions (P = 0.049‐0.109, d = 0.33‐0.38). Then the person will experience "flexion motion with load intolerance."
