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 Results may not be published yet.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.

Summary

Researchers compare two ways of doing plyometric training, a type of jump exercise, in 40 male basketball players aged 12 to 16. One group does six short sessions a week with 40 jumps each; the other does two longer sessions a week with 120 jumps each. Both groups complete the same total weekly jump volume over 8 weeks. The trial measures changes in jump height, power, sprint speed, agility, and body composition to see whether the shorter, more frequent approach works as well.

What this could mean

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

Active substance
plyometric training, a type of jump-based exercise
What this could lead to
If microdosing works as well as longer sessions, coaches could fit effective power training into busy school and practice schedules.
What could go wrong
The trial is small, with 40 teenage boys, so results may not apply to girls, other sports, or older athletes. Training studies also depend on how well participants stick to the program.
