I went back and re-read the article - Prof. Delp set as his "control group" the astronauts who only made it to LEO.
So all the lack of exercise has already been taken into account. The only things different between the LEO astronauts and the Apollo astronauts are the duration of the missions and the amount of radiation received. And "duration of the missions" is covered by the Skylab astronauts.

the same sovereign, servants of the same law."
