Mayo Clinic on the Summer Olympic Games: Better Athletes, the Physiology of Performance, the Lactate Threshold, the Aging Athlete and Much More Aug 1, 2008
"As scientists search for genes and the determinants of performance, they keep drawing a blank. There have been no major gene discoveries saying that this gene really confers championship status or the potential for championship status of one person." Sports are complex behaviors for biologists, he says. Many genes contribute to performance, but it isn't likely that one individual would have the right combination of all genes that would give you a natural competitive edge, he says. (PR Newswire)
