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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

Researchers compare two aquatic kicking programs to see which better improves core stability and sprint performance in competitive swimmers. Thirty healthy male swimmers with at least two years of racing experience join the study. Both groups also do the same land-based core conditioning. Swimmers are tested at the start, at Week 4, and at Week 8 on how long they can hold a rigid streamline position and how fast they swim short freestyle sprints.

What this could mean

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

Active substance
dolphin kick streamline training, an aquatic kicking program
What this could lead to
If it works, swimmers and coaches could gain clearer guidance on which kicking style best builds core stability and sprint speed.
What could go wrong
This is a small, short study of 30 healthy male swimmers, so any differences may be modest and may not apply to other swimmers or stroke specialties.
