The tendency of female adolescents to exhibit greater motor control on a balance beam than male adolescents are largely due to females:

Narrow Hips relative to shoulder width

Lower center of gravity

Longer legs relative to total height

None

The position of the center of gravity of an object affects its stability.

The lower the center of gravity (G) is, the more stable the object. The higher it is the more likely the object is to topple over if it is pushed.
