A flurry of excitement about the idea of genes for athletics prowess took off in 2003 when Australian scientists found that a gene called ACTN3 has certain variants which may give the muscles of elite athletes a performance advantage.”But there is no single gene that accounts for speed and power, or for sprinting.
