Simone Biles said on Monday the mental health concerns that led to her dramatic withdrawal from several events at the Tokyo Olympics had begun before she even arrived in Japan.
The US gymnastics superstar caused a sensation at the Olympics last month after pulling out of the team final competition before later withdrawing from the individual all-around competition.
Biles, 24, regarded by many as the greatest gymnast of all time and who had been strongly tipped to win multiple gold medals in Japan, said she had withdrawn in order to prioritize her mental health.
In a video conversation with her mother released by sponsors Athleta on Monday, Biles said her problems had built up over time.
