If by space you are referring to volume, then NO. Matter doesn't lose a considerable amount of mass when it changes volume. See: Law of Conservation of Mass. However, if the volume increases and the mass does not the density of the object decreases. Summary: No. It doesn't lose mass. But it does lose density.
if anything it would be reasonable to expect it to lose mass.
No the heart does not lose mass.

Mass, being the total amount of matter in an object, would change when you run, because you sweat when you run.

Use your muscles or you will lose muscle mass and strength.
