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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 trial investigates whether a four-week respiratory training program — involving diaphragmatic breathing and gradually increased resistance — can improve reaction time, agility, speed, and endurance in young football players. Fifty healthy boys aged 13 to 15 who have played football for at least two years will take part. Their performance will be measured using light-sensor reaction tests, agility drills, sprints, and a shuttle-run endurance test before and after the training.

What this could mean

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

Active substance
respiratory training (breathing exercises with progressive resistance)
What this could lead to
If breathing exercises improve reaction time and agility, this could point toward a simple, drug-free way to boost sports performance in young athletes.
What could go wrong
This is a small, early-stage trial in healthy boys, so results may not apply to other groups. The training effect may be small or not translate to real-game performance.

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 50 people

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

Expected to start

Sep 2026

An estimate. Start dates often move.

Expected to finish

Jun 2027

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.
