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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 tests whether velocity-based strength training, which adjusts weights based on movement speed, improves sprint, jump, and endurance more than traditional percentage-based training in young football players. About 58 male players aged 16 to 18 with at least five years of competitive experience will follow a six-week program, three days a week, either using velocity-based methods or traditional ones. Researchers will measure changes in vertical jump, 20-meter sprint, and aerobic capacity before and after the program to see which approach works better.

What this could mean

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

Active substance
Velocity-based strength training (squat and bench press) compared with traditional percentage-based strength training
What this could lead to
If velocity-based training proves superior, it could give coaches a more effective way to improve sprint, jump, and endurance in young athletes.
What could go wrong
This is a small, early-stage study in a specific group of male youth players, so results may not apply to other athletes or ages. The training effect could also be similar between methods.
