Summary

This study aims to conduct a cluster RCT intervention study with adolescents in Denmark and investigate whether the FIT FIRST concept can improve young people's bone health. We hypothesize that students from the schools randomized to the intervention arm will show greater improvements in bone health than students randomized to the control arm. The experiment will be of societal relevance in relation to evidence for the effects of implementing high-intensity physical activity in school.
