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.

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 Results may not be published yet.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

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 tested whether doing push-ups with a cuff that partially restricts blood flow to the arms can improve upper body explosive power in volleyball players. Thirty healthy athletes aged 18-25 completed the trial. The goal was to see if this technique, called blood flow restriction exercise, could enhance performance more than regular push-ups.

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) cuff
What this could lead to
If successful, this could point toward more efficient training methods for athletes using blood flow restriction.
What could go wrong
This is a small, early-stage study in healthy young athletes, so results may not apply to other groups. The effect on performance is acute and may not translate to long-term gains.
