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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 study compares two types of blood flow restriction (BFR) training — concentric and eccentric elbow exercises — in healthy adults aged 18 to 35. Participants perform light-weight arm exercises with a cuff on the upper arm to partially restrict blood flow. The goal is to see which exercise type better improves reaction speed, muscle strength, and oxygen use in the muscle.

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 training combined with concentric or eccentric elbow flexion exercises
What this could lead to
If it works, this could point toward more efficient exercise programs for improving muscle strength and reaction speed with lighter weights.
What could go wrong
This is a small, early-stage study with only 34 healthy participants, so results may not apply to other populations or real-world settings.

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

About 34 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Nov 2026

An estimate. End dates often move.

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

18 to 35 years

Sex

Anyone

Healthy volunteers

Accepted

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