Overview and Core Takeaways
At the Tokyo 2020 Olympic Games, U.S. artistic gymnast Simone Biles withdrew from several events, including team finals and individual all-around, citing medical and mental health concerns commonly referred to as the twisties. Biles emphasized that her decision was rooted in safety, not failure, highlighting the importance of athlete well-being over medal counts in elite sport. This evergreen explainer outlines what occurred, the conditions involved, and why the response reshaped conversations around mental health in high-performance settings.
Background on Simone Biles
Simone Biles is the most decorated gymnast in world championship history and one of the most decorated American athletes of all time. Her career is defined by extraordinary difficulty, consistency at the highest level, and advocacy for athlete welfare. Before Tokyo 2020, Biles had publicly addressed past trauma and the role of mental health in sport, establishing a baseline for understanding her decision to step back under pressure.
What Prompted the Withdrawal: The Twisties and Safety
The Twisties Explained
The twisties are a temporary disruption in spatial awareness and body kinesthetic control, often described as a "missing reference" for where the body is in space during flight. In gymnastics, this creates serious safety risks on twisting and rotating skills, regardless of technical training or psychological readiness. Coaches and sports medicine professionals treat the twisties as a medical concern that can affect any tumbling athlete under stress or fatigue.
Decision Context in Tokyo
During the Tokyo 2020 Games, Biles reported feeling disconnected and unsafe attempting elite skills. After a delayed reaction on vault in the team final, she withdrew from the team event and the all-around, prioritizing health over competition results. Her public communications and the U.S. Olympic and Paralympic Committee’s statements affirmed that this was a medically grounded, athlete-first choice.

The Role of Mental Health in Elite Sport
Elite gymnastics demands extreme physical and psychological conditioning, with long training hours, frequent travel, and intense competitive expectations. Mental health conditions such as depression, anxiety, and trauma responses are documented among high-level athletes. The conversation prompted by Biles’ withdrawal helped normalize discussions about when an athlete should step back to protect their well-being and how support systems should respond without stigma.
Impact on Athletes, Sport, and Governance
Biles’ decision influenced coaches, governing bodies, and peers by demonstrating that safety tramescoring or podium outcomes. Many organizations reviewed policies on mental health accommodations, concussion protocols, and return-to-competition criteria. Media coverage shifted toward athlete agency and informed consent, while fans learned to separate individual outcomes from legacy and performance quality.
Long-Term Implications and Best Practices
For athletes, the legacy of this moment is a clearer expectation that medical and mental health needs are valid reasons to modify or pause competition. Best practices for entourage and governing bodies include proactive mental health planning, access to sport psychologists, and protocols that treat twisties and similar conditions like any other performance-impacting medical issue. Continued education, cultural change, and longitudinal athlete welfare research remain important priorities.
Conclusion and Key Takeaways
Simone Biles’ withdrawal at Tokyo 2020 was a medically informed, athlete-led decision that prioritized safety over competition. It brought enduring attention to the realities of the twisties and mental health in gymnastics. Moving forward, the focus remains on structural support, evidence-based protocols, and cultural norms that honor both excellence and well-being in sport.
