Genetic analysis companies are forging alliances with personal trainers, chiropractors, and coaches around the world to market genomics tests that they say can help athletes at all levels tailor their workouts to their DNA.
They have struck deals with the Baylor University football team in Texas, with soccer teams in the English Premier League and in Egypt, and with an elite training facility in Arizona for top track and field athletes, including several who competed in the Rio Games.
Yet there is little science to back up the claims that a genetic analysis could identify if a particular athlete is, say, predisposed to benefit from a certain type of exercise, prone to tendon injuries, or wired to have trouble recovering from tough workouts.
