Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will undergo a physical activity programme, provided online by a smartphone app. The physical activity programme will be completed at home and consists of fast walking (a minimum of 10000 steps) plus jumping (60 rope jumps), to stimulate bone growth.
Regarding what 'fast walking' is considered, although the app will register the step rate, participants will be told to just walk at a speed that impedes talking and impedes a normal conversation. Later on during data analysis we intend to correlate results with the pace registered by the app.
The 10000 steps should be completed daily and will be taken overall (that is, not additionally to current exercise levels).
Adherence to the intervention will be checked daily, as the participants will wear an activity tracker. The intervention will not be individualised, as it will be the same for all the members of the intervention group.
The intervention will last for 6 months.
