In an interview with Slate, David Epstein, author of The Sports Gene, argues that downplaying the genetic aspects of athletic talent is harmful:
I think it’s become really detrimental, because now there’s this early hyperspecialization in sports, and there are very few sports where the science shows that actually helps and others where it shows it’s detrimental. What the more recent science is suggesting is that you should have a sampling period, when you find what activity and training fits your genome best before you specialize in your mid-teen years. And so I really think we’re doing some athletes a disservice with that message, but some of the scientists, sports psychologists particularly, have felt like saying, “Well, you can achieve anything,” is the message you should put forward. Well, the converse of that is, if you didn’t get to the NBA, it’s because you didn’t work hard enough. It’s a theme which maximizes the sort of “free will” message, and it’s self-helpy, which is why people enjoy it, even when most people in the back of their head realize that they have proclivities which make them better at one thing than another.
Razib Khan enjoyed Epstein’s interview with NPR:
[Epstein] reports that 17 percent of men over the the height of seven feet (2.14 meters) between the ages of 20 and 40 in the United States are playing in the NBA!
Obviously there is no gene which is guaranteed to make you an NBA star, but having the allelic profile which predisposes you to being seven feet tall obviously helps. It also illustrates the ridiculousness which the “10,000 hour rule” has been taken to in popular culture. Practice matters, and, talent matters. At extremely high levels of performance one often needs to have focus to engage in repetitive tasks over and over. But, one also likely needs a preternatural complement of genes. Most of the children of NBA players do not become professional basketball players, but the probabilities are far higher. Epstein outlines these sorts of facts in a breezy and concise manner in the interview, as well as dismissing the infantile disorder of genetic determinism which results in the purchasing of DNA kits which will tell you if your child is an athlete or not.
In an interview with The Atlantic, Epstein explains how the field of genetics is already being used to improve athletic performance:
I think genetically tailoring your diet is already a thing; for example, one of the doctors I talked to for the book also does genetic testing for retired athletes. And he knows who’ll respond better to fish oil supplements for brain health, things like that. I think we’ll start to see more of that.
One other thing that’s happened organically is individualized training. Great coaches sometimes do this intuitively: They have these intuitions about genetics, in that they recognize that certain athletes are responding to certain types of training while others aren’t. There’s one scientist I talked to who actually takes biopsies, so that he has the muscle-fiber types of athletes—percentages of fast-twitch and slow-twitch, stuff like that—and develops training regimens for them accordingly. Most athletes are recreational and won’t be getting muscle biopsies, but hopefully we can start paying more attention to what individuals respond to.
