Hi dear friend,
Women have different shapes and forms of pelvic , so , the angle of acetabulum and head of femur change because of these differences . We see different shapes and body forms ( anatomical difference) between women too ! specially different hips and forms of legs (tight and knee ,...) again due to these variations in the angle of acetabulum and head of femur . These anatomical differences plus phisiological differences cause different perfomance and different strenght between ladies and between ladies and men .
