简要总结
The approach of a competition can be associated to a decrease in sleep duration and quality which can negatively impact athlete's performance and health (injury risk, fall, accident). Ultra-endurance competitions even involve partial and/or total sleep deprivation over one or several nights. Studied investigating this question suggest that endurance performance under sleep deprivation is altered, mainly because of an effect on the rate of perceived exertion (RPE), which regulates effort intensity. One of the methods used by athletes to limit the impact of sleep deprivation in competition is to implement sleep extension in the days prior to a competition. However, few studies have investigated the impact of sleep deprivation et its reproducibility on performance and fatigue during a prolonged running exercise, as well as the efficiency of prior sleep extension. The importance of such a preventive measure might also depend on individual resistance to sleep deprivation, which is variable between persons and could have genetic determinants. This aspect remains under-studied, particularly regarding the impact of sleep deprivation on physical performance. Therefore, this study aims at investigating the effects of sleep deprivation and prior sleep extension on prolonged duration performance.

研究组 & 干预措施
PT (total sleep deprivation).
This group will perform an incremental running test, conducted until exhaustion, in:
- a control condition (usual sleep)
- a one-night condition of partial sleep deprivation
- a one-night partial sleep deprivation condition with 5 nights of prior extension. The order of conditions will be randomized.
干预措施: Total sleep deprivation (Other)
REP (reproducibility).
This group will perform an incremental running test, driven to exhaustion, after a night of total sleep deprivation twice, at least two weeks apart.
干预措施: Reproductibility (Other)
PP (partial sleep deprivation)
This group will perform an incremental running test, run to exhaustion, in :
- a control condition (usual sleep),
- a one-night total sleep deprivation condition
- a one-night total sleep deprivation condition with 5 nights of extension beforehand. The order of conditions will be randomized.
干预措施: partial sleep deprivation (Other)
