*More recently, Sanya Richards-Ross, a Jamaican-American sprinter, used Buteyko’s techniques to win three Olympic golds in the 4x400 meter relay (in 2004, 2008, and 2012) and gold in the 400 meters in 2012. She was ranked as the top 400-meter runner in the world for a decade. Photos of Richards-Ross with her mouth closed and a placid look on her face as she destroys the slack-jawed and gasping competition have become the stuff of legend.
