About this trial
The goal of this cluster randomised controlled trial is to investigate the effects of the FIT FIRST Teen program on adolescents' physical fitness, motivation, and well-being, as well as the implementation of such a program within schools. The main questions it aims to answer are:
Research Question 1: Does the FIT FIRST Teen program improve cardiorespiratory fitness, body composition, and muscle strength among adolescents?
Research Question 2: Does the FIT FIRST Teen program improve well-being, motivation towards physical activity, and body image among adolescents?
Research Question 3: What are the challenges that teachers and schools will face regarding the implementation of the FIT FIRST Teen program?
The research team will compare the FIT FIRST Teen program to a control (usual physical education curricula) to see if such a program improves adolescents' physical fitness, motivation, and well-being. Participating schools will:
* Participate in a training course, where the core principles of the FIT FIRST Teen program will be delivered. * Implement the FIT FIRST Teen program for a full school year (three 45-minute lessons a week). * Keep a logbook where the weekly practised activities will be reported.

Trial outcomes
Primary outcomes
Cardiometabolic Fitness
The cardiometabolic fitness profile will be evaluated by using the Yo-Yo test measured as the total distance in meters as an indicator for the participants\' ability to perform intermittent exercise and their cardiometabolic fitness. The longer the distance, the better the cardiometabolic fitness of the participants.
Implementation
Implementation of the FIT FIRST Teen Program will be evaluated.
Secondary outcomes
Health-Related Quality of Life
Health-Related Quality of Life will be measured using the KIDSCREEN-27 inventory.
Body Image
Adolescents' body image will be measured using the Body Appreciation Scale-2.
Body Functionality Appreciation
Adolescents' body functionality appreciation will be measured using the Functionality Appreciation Scale.
