The mental health concerns are being discussed on and off the Olympics venue at the moment. The good thing is that both the athletes have been brave enough to open up about their mental health, which had been considered a taboo in the competitive sporting arena.

While CNN quoted Osaka as saying that she felt that her "attitude wasn't that great because I don't know how to cope with that pressure so that's the best that I could have done in this situation," Biles said: "I have to focus on my mental health and not jeopardize my health and well-being."

Support flowed in for Biles after her exit from former U.S.

gymnast Kerri Strug and former U.S. Olympic swimmer Michael Phelps. An advocate for better mental health, Phelps said that Olympic athletes need someone who they can trust and that it has to be somebody that can let athletes be themselves, let them be vulnerable, and someone who is not going to try and fix them.
