Elite sports is increasingly being shaped by more than training volume and talent. A growing body of performance thinking points to circadian rhythm--the body's internal 24-hour clock--as a key factor in energy, focus, and recovery.
According to Mickey Beyer-Clausen, co-founder and CEO of Timeshifter, aligning daily routines with natural biological timing can help athletes perform at their best. He notes that peak competition results often appear in the late afternoon, when body temperature and alertness tend to rise together.
This approach is especially valuable for athletes who travel across time zones. By managing light exposure, sleep timing, and daily habits, they can reduce the effects of jet lag and better match competition schedules to their strongest hours. Beyer-Clausen also says the method has been applied in high-level environments, including preparations connected to the 2026 World Cup.
The conversation also highlights research from Dr. Stephen Lockley, whose work on sleep and circadian science has supported both athletes and astronauts in maintaining alertness under demanding conditions. The broader message is clear: timing can be as strategic as training.
As more competitors and coaches embrace chronotype-based planning, circadian science may become a standard tool in future performance systems, helping athletes unlock more precise and sustainable excellence.
