Now, if I am not mistaken, a gymnast can rotate around his or her axis while spinning, and they can speed up and slow down their speed of rotation by changing the radius part of their moment of inertia; you know, extending legs and arms outward or bringing them inward. I want to know, however: can a gymnast, or any athlete for this matter, change the speed and direction of their rotation in mid air above the ground without changing their moment of inertia by bringing their body parts in and out? Is it even possible at all? Why or why not?
