Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This trial asks whether the 'first-night effect'—poorer sleep in an unfamiliar place—impairs next-day strength and muscular endurance, and whether men and women respond differently. Thirty-two resistance-trained adults (16 women, 16 men) will sleep 8 hours at home and 8 hours in a lab, then perform bench press, squat, grip, and jump tests. The goal is to see if sleep environment affects physical performance and if the impact varies by sex.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Sleeping in a laboratory versus at home (behavioral intervention)
What this could lead to
If sex differences are found, training and competition schedules could be tailored to account for sleep environment effects on performance.
What could go wrong
This is a small, early-stage study (32 people) and results may not apply to all athletes or real-world settings. The effect may be small or inconsistent.
