The most closely watched members of the United States Olympic gymnastics team in Tokyo will not be superstar Simone Biles or her fellow athletes, but the doctors and therapists hired to treat them as the sport works to put years of scandal behind it.

Following the 2016 Rio Games, USA Gymnastics was rocked by revelations of systemic abuse of athletes that triggered mass resignations, lawsuits, investigations and bankruptcy filings.

It also forced the introduction of long overdue health and safety protocols that forbid medical personnel, coaches, judges and other event staff from having one-on-one time with an athlete, and that will be visible in Tokyo.
