What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
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
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 Results may not be published yet.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 study looks at whether a single session of hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can increase muscle strength in healthy, physically active adults aged 18 to 45. Participants will do a mid-thigh pull test after either the real oxygen treatment or a sham (fake) version, and the results will be compared. The trial is small (48 people) and aims to gather knowledge, not to treat any disease.

What this could mean

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

Active substance
Hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber)
What this could lead to
If it works, this could suggest that hyperbaric oxygen might temporarily enhance muscle performance in healthy people.
What could go wrong
This is a very small, early study in healthy volunteers, not patients. The effect, if any, may be tiny or not meaningful for real-world use. There is no disease being treated.
