The rotational inertia is the resistance that an object has to changes in its rotational motion. When the leg is straight, the majority of its mass is distributed farther away from the axis of rotation (i.e., the hip joint). This larger distribution of mass increases the leg's rotational inertia, making it harder to rotate. Therefore, the rotational inertia of your leg is greater when it is straight.
