OLYMPIC-S: Outcomes of a Life-stYle Multicomponent Physical-activity Intervention in Children at School
Spain893 participantsStarted 2026-02-02
Plain-language summary
OLYMPIC-S is a cluster randomized controlled trial evaluating a four-month school-based intervention designed to increase moderate-to-vigorous physical activity and promote healthy habits among children in the fourth, fifth and sixth grades of primary school. Fifteen schools and approximately 1,200 children will participate. Schools will be randomized to the Olympic School intervention or to a control group continuing usual school activities.
Intervention schools will introduce 15 minutes of physical activity during each school day. Teachers may choose between outdoor walking or running activities based on The Daily Mile or structured movement video sessions from the Born to Move programme. A gamified web platform will record the activity performed, display each school's collective progress through an Olympic journey, unlock educational content and reinforce messages related to physical activity, healthy eating, hydration and sleep.
Outcomes will be assessed at baseline and immediately after the four-month intervention. The primary outcome is daily moderate-to-vigorous physical activity measured using the PAU-7S questionnaire. Secondary outcomes include dietary habits, fruit and water consumption, sleep, emotional well-being, health-related quality of life, adherence, platform use, feasibility and acceptability. Post-intervention focus groups with children and teachers will complement the quantitative evaluation.

The intervention content is intended for approximately 8-12-year-old children, but the actual lower and upper age limits should be based on the expected ages of pupils in the participating fourth-, fifth- and sixth-grade classes.
Inclusion Criteria:
* Enrolled in the fourth, fifth or sixth grade at a participating primary school.
* Parent or legal guardian has provided written informed consent.
* Child has provided informed assent.
* Child is able to complete the study questionnaires with the support normally available during classroom administration.
* Child is expected to remain enrolled at the participating school throughout the four-month intervention period.
Exclusion Criteria:
* Written parental or legal-guardian consent has not been obtained.
* The child does not provide assent or withdraws assent.
* The child cannot participate in the study assessments according to the criteria established in the approved protocol.
Teacher focus-group eligibility:
Inclusion criteria:
* Teachers or other school staff who directly participated in implementing Olympic School at an intervention school and who provide written informed consent.
Exclusion criteria:
* Teachers or school staff who did not participate directly in implementation or who do not consent to the audio-recorded focus group.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is focused on increasing moderate-to-vigorous physical activity in children over 4 months at school — does my child's current activity level or health status make this kind of structured physical activity program something worth exploring?
2The trial is listed as 'active not recruiting,' which means they're no longer enrolling new participants — are there similar school-based physical activity programs or interventions my child could still access or benefit from right now?
3Since this study is categorized as Phase NA, meaning it's more of a behavioral or lifestyle intervention than a drug trial, what does that mean for how well-established the safety and effectiveness of this type of program actually is?
4This trial measures changes in daily physical activity over just 4 months — if my child has specific health concerns related to physical inactivity, would a 4-month school-based program be enough, or should we be looking at longer-term or more individualized options?
5Given that this is a school-based multicomponent intervention, how much of my child's participation would depend on their school's involvement, and is that something our school would realistically be able to support?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
