Explanation:

Decrease moment of Inertia

-A swimmer bends his body to decrease moment of inertia. This is because during a somersault, a full rotation is to be performed in a limited amount of time. Thus because moment of inertia is lesser, the body rotates faster and hence able to complete the somersault.
