What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 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 Results may not be published yet.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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This completed study looked at how blood flow restriction (BFR) exercise affects stem cells and immune cells in the muscles of healthy young men. It also tested whether taking NMN (a vitamin B3 precursor) or vitamin C before and after exercise changes those effects. The goal was to better understand how these interventions influence muscle repair and immune response.

What this could mean

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

Active substance
Blood flow restriction (BFR) training, NMN (vitamin B3 precursor), and vitamin C
What this could lead to
If successful, this could help scientists understand how BFR exercise and certain supplements influence muscle repair and immune response.
What could go wrong
This is a small, early-stage study in healthy young men only, so results may not apply to other groups or lead directly to treatments.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

60 people

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

20 to 30 years

Sex

Male participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
