Toes-up stance was associated with greater pre-to-post squat ME deviation and greater anticipatory GEV constriction, both consistent with greater initial displacement from optimality.

This online control without limb-target regulation was likely the result of impulse regulation. We suggest that impulse regulation was used because it can modulate movement velocity without a large cost to temporal precision.
