NBC does not meet WP:MEDRS standards for claims about athletic abilities, and this explanation is not completely correct. Conservation of angular momentum only demands that the *ratio* of the initial and final angular velocities is inversely proportional to the *ratio* of the initial and final moments of inertia; a more complete explanation explains why the latter differs. The Harvard source makes no connection to the moment of inertia. undo

This does not follow from the mathematical definition of the moment of inertia, as for *any* mass and *any* given value for the moment of inertia, it is possible to construct a body such that if given the relevant density (muscle or fat), the body will have that mass and that moment of inertia. undo Tags: Undo Mobile edit Mobile web edit Advanced mobile edit
