New research published in the Annals of Internal Medicine finds that injections of human growth hormone can boost sprint capacity in athletes. The study, funded by the World Anti-Doping Agency, reports that while strength and power were unaffected, human growth hormone improved the sprint capacity in men and women by 3.9 percent over a placebo group. When results in track competitions come down to fractions of a second, it's enough to make a last-place sprinter the winner. And while the substance cannot be detected in urine, it can be found in a blood sample if a test is performed within a few days of use. Should athletic organizations start testing for human growth hormone?
