Sleep extension to reduce performance loss from sleep deprivation
Official title: Effect of Sleep Extension in Prevention to Sleep Deprivation on Running Endurance Performance
Run by Centre Hospitalier Universitaire de Saint Etienne · NCT06928168 · Data updated 2026-11-12
This trial tests whether adding extra sleep in the days before long runs helps healthy adult runners resist the fatigue and performance decline caused by partial or total sleep deprivation.

Is this trial a fit for you?
✓Likely a good fit
Healthy men and women aged 18–50 who run at least one session longer than one hour per week, normally sleep 6–8 hours per night, have no chronic medical conditions, and are not shift workers or currently in competition.
✕Probably not a fit
People with chronic illnesses, night-shift workers, those with sleep disorders or excessive daytime sleepiness, or those whose usual sleep falls outside 6–8 hours may not be represented and therefore may not benefit from the results.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Healthy adults who run regularly will follow a period of either their usual sleep or prescribed sleep extension in the days before a prolonged running exercise. Participants will then be exposed to partial or total sleep deprivation and complete endurance running tests while researchers record performance, rate of perceived exertion (RPE), and fatigue measures. The protocol explicitly examines reproducibility of effects and individual differences in resistance to sleep loss. Outcomes will compare whether prior sleep extension lessens the negative impact of sleep deprivation on sustained running performance.
Why it matters
Potential benefit: If successful, this could provide a simple, low-risk strategy—getting extra sleep before events—to reduce fatigue and help preserve endurance performance during sleep-deprived competitions.
How similar studies have gone: Small prior studies suggest sleep extension before endurance events can reduce perceived exertion and partly protect performance under sleep loss, but published evidence is limited and reproducibility remains uncertain.
