Influence of Chronotype on Cycling Performance in Simulated 20‐km Time Trials—A Pilot Study
Journal of Sleep Research, Volume 35, Issue 3, June 2026.Evening‐type athletes show improved cycling performance later in the day, whilst morning types peak earlier. These differences appear linked to variations in mental readiness and sleepiness, highlighting the importance of considering chronotype in performance planning.
