The Sports Gene: Inside the Science of Extraordinary Athletic Performance Page 32

  Additionally, I gained invaluable background at conferences, like the 2010 British Association of Sport and Exercise Sciences conference, and several editions of the American College of Sports Medicine annual meeting. By 2012, I’d been pesky enough in the sports medicine world that I was invited as an ACSM speaker. At that meeting, I also had the profound pleasure of co-organizing, with Yannis Pitsiladis—he of the globe-trotting DNA gathering—an ACSM panel on the nature/nurture of sports expertise. The panel included: Claude Bouchard (the most influential exercise geneticist in the world); K. Anders Ericsson (the man known for the 10,000 hours and the study of deliberate practice); and Philip L. Ackerman (the motor skill acquisition expert who designed the air traffic controller test). Needless to say, the debate was intense, but the dinner afterward amiable and delightful. To me, it was science at its best, contentious and collaborative all at once.

  Here I present copious but not comprehensive citations. Throughout the text, it is often easy to track the books and studies I used, as I frequently name the researchers and/or publications. For example, dozens of studies by Janet Starkes and Bruce Abernethy were useful for the first chapter. However, I will not recount their stacks of papers here. These notes are meant to highlight the sources of facts when the source isn’t spelled out in the text, and as a detailed point of entry for anyone interested in exploring primary sources. The vast majority of spoken quotes in this book came directly from my interviews. Whenever that is not the case, the source is identified either in the text itself or here.

  The Gene-Free Model of Expertise

  2 Jennie Finch told me in an interview that she was nervous about Pujols hitting a line drive back at her, and that Bonds refused to allow certain pitches to be filmed. Many of Finch’s strikeouts of major leaguers, and Pujols’s “I don’t want to experience that again” quote, can be found in the DVD titled MLB Superstars Show You Their Game (Major League Baseball Productions, 2005).

Land, Michael F., and Peter McLeod (2000). “From Eye Movements to Actions: How Batsmen Hit the Ball.” Nature Neuroscience, 3(12):1340–45. McLeod, P. (1987). “Visual Reaction Time and High-Speed Ball Games.” Perception, 16(1):49–59.

  5 Joe Baker (York University) and Jörg Schorer (University of Muenster) taught me about reaction speed and gave me an occlusion test in which I had to tend a virtual goal against female professional handball players. My results can be inferred from the original chapter 1 title in a first draft of this book: Beat by a Digital Girl.

  29 Most details come from Thomas himself and competition records, but the quote by Thomas’s cousin that Thomas “doesn’t know that a track goes around in a circle,” and Clayton’s “didn’t know how to warm up” quote both originally appeared in a 2007 press release issued by the U.S. Track and Field and Cross Country Coaches Association titled: “An Improbable Leap into the Limelight.”
