An article in the August 8 issue of Sports Illustrated cited the research of Professor of Psychology Wendy Sternberg.“The Truth about Pain: It's In Your Head,” by David Epstein, explored the ways athletes deal with pain and discussed Sternberg's research on stress-induced analgesia, which is the temporary absence of pain after injury.  Wrote Epstein:“[Sternberg] tested the pain sensitivity of track athletes, basketball players and fencers at Haverford immediately after competition, compared to two days before and two after. Sure enough, on game day the athletes were less sensitive to heat or cold. For Sternberg the key implication was that athletic competition kicks in the body's pain-inhibition circuitry.”
