In his PhD work, he looked at what we call free radical stress and this was a big topic back in the 90s. He learned how to remove the heart from the rat and then put it on or connect it to an artificial circulation where he could manipulate different variables like exposure to free radicals. His research is more medical than it is sports science. But if you study the heart, there is a connection to endurance obviously.
