The Unbeatable Body: Pushing the Limit

On the move for the sake of science, subjects in a Yale University fitness study are measured against each other. Thirty-seven-year-old Rich (left) and 60-year-old Larry (center), both of whom exercise regularly, are neck and neck in cardiovascular fitness. By comparison, 35-year-old Salvatore (right) leads a sedentary life that negatively affects his cardiovascular and respiratory fitness. His heart and major arteries are visibly smaller, and his VO2max—the amount of oxygen his body is able to use—is lower. The brighter colors in his leg show that his muscles had to work harder to complete an hour on the treadmill. The point? Our bodies are programmed to exercise.

Exercise study conducted at Yale University School of Medicine. Study team: Thomas B. Price, Raynald Bergeron, Jim Rambo, Terry Hickey, Thomas R. McCauley, Adam Anderson, John C. Gore, and Douglas L. Rothman. Study subjects shown: Salvatore Iorio, Richard Kennan, and Lawrence W. Rosen.



Magnetic Resonance Imaging (MRI) scans of the subjects provided cross-sectioned images of muscle shape, bones, and blood vessels. The range of color intensity also came from MRIs. Medical imaging software then reconstructed these internal parts in 3D. Finally, computer software merged the medical images with the photos of the subjects.
