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.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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

Summary

This trial tests whether adding an 8-week TRX suspension training program to regular practice helps young male volleyball players improve body composition, explosive power, and sprint speed. About 26 athletes aged 14 to 18 will be split into two groups: one doing TRX twice a week plus their usual training, and one doing only their usual training. Researchers will measure vertical jump, leg and grip strength, sprint time, and anaerobic power before and after the program to see if suspension training offers an extra edge.

What this could mean

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

Active substance
TRX suspension training program
What this could lead to
If TRX training proves effective, it could offer a simple, equipment-light way for young athletes to improve explosive power, sprint speed, and strength beyond regular practice.
What could go wrong
This is a small, early trial with only 26 participants, so results may not apply broadly. The extra training could also add fatigue or injury risk, though the program is short and supervised.
