NCT ID NCT07617116

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study looks at whether professional soccer players with stronger lungs and breathing muscles also have better balance, faster reaction times, and greater endurance. Researchers will measure lung function, breathing strength, balance, core stability, and reaction speed in 31 players during a single session. No treatments are given—this is purely observational to uncover links between breathing and athletic performance.

What this could mean

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

What this could lead to
If successful, this study could help coaches and trainers understand which breathing skills matter most for soccer performance, potentially leading to targeted training programs.
What could go wrong
This is a small, observational study with only 31 players, so results may not apply to all athletes. It measures links, not cause and effect, and may not lead to any practical changes.

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

Show the full entry requirements

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

Inclusion Criteria: * Participants will be actively competing, licensed professional soccer players. -Participants will be engaged in regular, team-based training and competitive match schedules. * Participants will voluntarily provide written informed consent before any study-related physical performance assessments are conducted. Exclusion Criteria: * Participants will be excluded if they present with an acute upper or lower respiratory tract infection that could potentially affect pulmonary function or maximal respiratory muscle performance. * Participants will be excluded if they have a documented history of major cardiothoracic surgery. * Participants will be excluded if they have any diagnosed respiratory and/or cardiovascular disorder associated with dyspnea or impaired pulmonary mechanics. * Participants will be excluded if they present with any condition that elevates clinical risk during maximal inspiratory and expiratory pressure assessments. * Participants will be excluded if they have sustained an acute musculoskeletal injury within the preceding 6 weeks that could compromise maximal physical exertion during sport-specific performance testing.
