The investigator showed that a night of sleep deprivation halved the duration of an inspiratory endurance test and that this loss of endurance could be secondary to a lack of activation of the pre-motor cortex. However, the inspiratory endurance test is associated with a feeling of dyspnea that could lead to premature arrest, and the inspiratory drive is complex, both automatic and voluntary. The investigator can reproduce this results on a simpler drive.
During the execution of an exercise involving repeated contractions of the hand it is possible to record the activation of the pre-motor cortex corresponding to the phase of preparation of the movement. The amplitude of these premotor potentials is proportional to the developed motive force.
The purpose of this study is to assess the impact of sleep deprivation on the muscular endurance of non-dominant in healthy subjects.
Hypothesis: Sleep deprivation causes a decrease in manual motor endurance by decreasing cortical pre-motor control.
Main objective: To compare the motor endurance of healthy subjects after a night's sleep and after a sleepless night.
Secondary objective: To compare the amplitude of premature cortical control at the beginning of the endurance test after a night's sleep and after a sleepless night.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

The first endurance test is the endurance motor control test after a normal sleep night.
Behavioral: Normal sleep night
The first endurance test is the endurance motor test after a sleepless night.
Behavioral: Sleepless night
Usual hours of sleep
Total sleep deprivation the first night
Test duration
Time, in minutes, measured between the beginning of the endurance test and the end of the test, defined by the volunteer's inability to maintain a force of at least 30% of the maximum strength for 5 seconds.
Time frame: 1 hour.
Ran from Feb 2019 to primary completion in Mar 2020, 12 months.
Of 141 non-industry interventional studies with no phase under Sleep Deprivation, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 44. This study's 12 months is below that.
Counting every sponsor, half of 150 studies reached it within 17 months; a quarter within 7 and three quarters within 37.
