Many of us who have been watching Olympic athletic feats on television have probably wondered, "How can they do that?"
Michael Joyner has a better idea than most.
The Mayo Clinic doctor and former college runner studies the physiology of elite athletes in his lab. He's also a frequently cited expert in human performance and endurance. We talked to him about athletes and their vulnerabilities, how to win by relaxing and how the Olympics are a celebration of human diversity.
This conversation has been edited for length and clarity.
Q: Are you watching the Olympics?
A: Oh, God am I ever. I have my own athletic background. Plus I've got this long interest in human performance.
Q: What have you found most compelling?
A: Just the overall age range of some of the athletes. We've got some relatively senior people participating in sports, and then we have some really young people in the swimming, gymnastics, and so forth. So I think we're seeing the range of excellence play out where that age range used to be much tighter in many sports.
