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 Results may not be published yet.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

Summary

This study looks at whether adding foot core exercises to regular strength training can improve jump performance in professional volleyball players. Forty-three male players will be split into two groups: one doing only strength training, the other adding foot exercises. Jump height and force will be measured using a special system called ForceDecks.

What this could mean

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

Active substance
Foot core exercise program
What this could lead to
If it works, this could point toward better training programs that improve jump performance and reduce injury risk in volleyball players.
What could go wrong
This is a small, early-stage study with only 43 participants, so results may not apply to all athletes. The exercises may not lead to significant improvements over standard training.
