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 Results may not be published yet.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

This study compares two 20-week strength training programs—linear and nonlinear periodization—in schoolchildren aged 12-13. The goal is to see which approach better improves motor performance, such as jumping, throwing, and agility. The programs are done three times a week during extracurricular sessions. Results could guide schools in choosing effective exercise programs for children.

What this could mean

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

Active substance
periodized strength training program
What this could lead to
If successful, this could help schools design better physical education programs to improve children's motor skills and fitness.
What could go wrong
This is a small, early-stage study in one region, so results may not apply broadly. The training may not outperform standard physical activity.
