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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study explores how blood flow restriction (BFR) training—using a pneumatic cuff during low-intensity walking—affects muscle oxygenation and blood lactate levels. Researchers compare elite track athletes with healthy sedentary individuals to see if BFR triggers different muscle adaptations. The goal is to understand whether this technique can enhance training efficiency without heavy loads.

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 using a pneumatic cuff during low-intensity treadmill walking
What this could lead to
If successful, this study could reveal how elite athletes adapt differently to low-intensity BFR training, potentially leading to more efficient training methods.
What could go wrong
This is a small, early-stage observational study with only 46 participants, so results may not apply broadly. The BFR device must be used carefully to avoid injury.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
