    I think your are referring to the relationship between:
    the increasing strength of ventricular muscle as the volume of the ventricle is increased.

    Its a property of cardiac muscle.
    As the ventricle is filled with blood, the cardiac muscle fibers become more elongated.
    As the muscle fibers are elongated, they can respond with greater force when they contract.

    This has obvious benefits to organisms that rely on dependable blood flow.
