Registered users only| BACKGROUND: Specific physical loading
leads to enhanced bone development during childhood. A general
physical activity program mimicking a real-life situation was
successful at increasing general physical health in children.
Yet, it is not clear whether it can equally increase bone
mineral mass. We performed a cluster-randomized controlled trial
in children of both gender and different pubertal stages to
determine whether a school-based physical activity (PA) program
during one school-year influences bone mineral content (BMC) and
density (BMD), irrespective of gender. METHODS: Twenty-eight 1st
and 5th grade (6-7 and 11-12year-old) classes were clust
