Background and study aims
In Denmark, less than one-third of 11- to 15-year-old children are sufficiently physically active. Physically inactive children are more likely to gain excessive weight, be inactive later in life, and develop chronic diseases. Therefore, this study aims to improve the physical fitness and well-being of children with an evidence-based physical education program.
Who can participate?
10-12-year-old children enrolled in a school in Denmark
What does the study involve?
Student participants will receive a special physical education program based on FIT FIRST principles if their schools are randomly assigned to receive the program. In the remaining schools, student participants will attend physical education classes, as previously established by the school. All students will respond to a questionnaire and carry out physical tests during a school day at school start, at the end of the school year, and 1 year after the project.
What are the possible benefits and risks of participating?
The potential benefits are improved physical fitness and well-being after the FIT FIRST program is implemented. No side effects are expected.
Where is the study run from?
University of Southern Denmark (Denmark)
When is the study starting and how long is it expected to run for? (what are the overall start and end dates?)
January 2019 to July 2026
Who is funding the study?
Novo Nordisk Foundation (Denmark)

| Scientific title | The effects of FIT FIRST 20 on physical fitness, well-being, and sports-club participation in 10-13-year-olds |
| Study acronym | FIT FIRST |
| Study objectives | A school-based physical activity intervention will improve psychosocial well-being and physical fitness and increase sports club participation among school-aged children and youth (4th to 5th grade, 10-12 years). |
| Ethics approval(s) | Ethics approval not required |
| Ethics approval additional information | Conforming to current legislation, the project was submitted to The Regional Scientific Ethical Committees for Southern Denmark. The committee decided that the project was exempt from the obligation to notify. Notification of this decision was forwarded via email on 01/05/2023. |
| Health condition(s) or problem(s) studied | Well-being and physical fitness |
| Intervention | Participating schools are randomly assigned to the intervention group, the intervention and booster group, or the control group. The method of randomisation is stratified. The first and second strata include the schools recruited in the first and second recruitment rounds, respectively. As recruitment continues until summer 2024, new strata will be formed at a later stage. The intervention and intervention-and-booster schools will implement three weekly 40-minute FIT FIRST lessons during one school year. Intervention-and-booster schools will also receive an 8-week FIT FIRST 20 booster program half-school year after the FIT FIRST program is implemented. A booster is a strategy that is implemented after the end of an intervention to amplify its effects in the long term. It often applies the same principles of the original intervention within a shorter period, but more intensively. The control group will be offered the opportunity to implement the intervention 1 year later. Baseline measurements are conducted at the beginning of a school year, followed by post-intervention assessments at the end of the school year as well as 1 year after the end of the intervention for all participating schools. |
| Intervention type | Behavioural |
| Primary outcome measure | All outcomes are measured at baseline as well as 1 year and 2 years after intervention start: 1. Physical fitness measured through the following physical tests: Yo-Yo IR1 Children´s test, the standing long jump test, arrow-agility test, balance test, the handgrip strength test, resting heart rate, blood pressure measurement, and InBody 230 bioimpedance measurements of body mass, lean mass, and fat percentage, 2. Well-being, measured using KIDSCREEN-27 3. Overall self-worth, measured using the Physical Self-Inventory (PSI-S) 4. Motivation to movement, measured using the perceived locus of causality questionnaire and the psychological need states in sport questionnaire |
| Secondary outcome measures | Sports club participation. Data are collected through a questionnaire. Questions include "which sports do you practice in your spare time?" and "how many times a week do you practice sports in your spare time?". Measured at baseline as well as 1 year and 2 years after intervention start. |
