NCT06223776

Brief Summary

The study aims to see how acute sleep restriction will affect women resistance trainers. Above all, the investigators will be interested in observing the relationship between shorter sleep and athletic performance, as well as other important aspects, such as their level of motivation to exercise, how much pain participants felt during exercise and how demanding they found exercise. The investigators assume that differences in subjective measures (such as pain levels, motivation and mood) will be most apparent.

Study Arms (2)

Normal sleep

NO INTERVENTION

The night before the experimental session, where participants will follow their habitual sleep-wake routines.

Sleep restriction

EXPERIMENTAL

The night before the experimental session (with sleep restrictions (SR)), where participants will experience acute sleep restriction the night before the test session (i.e., 3 h of early sleep restriction versus normal sleep).

Procedure: Sleep restriction

Interventions

Sleep restrictionPROCEDURE

Participants will experience a night of acute sleep restriction. During this night, they will sleep 3 hours less than usual.
