The Sports Gene

July 15, 2013
Are Tiger Woods, Jim Ryun, Serena Williams, and Michael Jordan natural athletes whose success in their own sports would have occurred whether they developed their gifts or not? Are some individuals genetically disposed to some sports, while others lack the genetic predisposition to succeed at the same sports? Sports Illustrated senior writer Epstein probes these questions in a disjointed study. Drawing on interviews with athletes and scientists, he points out that “a nation succeeds in a sport not only by having many people who practice prodigiously at sport-specific skills, but also by getting the best all-around athletes into the right sports in the first place.” Epstein observes that some scientists and athletes confirm that the so-called 10,000 hours of practice produces quality athletes, while others assert that the number of hours spent in practice matters little if a team has not already selected superior athletes in the first place. Epstein comes closest to scoring a home run in his provocative and thoughtful focus on the relationships between gender and race and genetic determination—why do male and female athletes compete separately, and are there genetic reasons to do so? and why do the best sprinters always come from Jamaica and so many long-distance Olympian runners hail from Kenya? While he helpfully leads readers into the dugout of modern genetics and sports science, his overall conclusions challenge few assumptions. In the end, he concedes that “any case for sports expertise that leans entirely either on nature or nurture is a straw-man argument.” Agent: Scott Waxman, Waxman Leavell Literary.
