NCT ID NCT07737548
First seen Jul 30, 2026 · Last updated Jul 31, 2026 · Updated 1 time
Summary
This trial tests whether a four-month school program called Olympic School can increase physical activity and promote healthier habits in children aged 8 to 12. Participating schools add 15 minutes of daily physical activity, supported by a gamified digital platform that tracks progress and rewards healthy behaviors. Researchers will measure changes in activity levels, diet, sleep, and well-being compared to schools continuing their usual routine.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

- What this could lead to

- What could go wrong
- This is a relatively short trial with subjective activity measurement, and results may not generalize beyond the specific program or setting.
