Non invasive methods to study the effects of exercise on bone geometry and trabecular bone microarchitecture in vivo : applications and limits in humans
Aim The purpose of this paper is to give an overview of the imaging techniques that are currently used to study the effects of exercise on bone architecture.
Current knowledge It is now widely accepted that the prevention of osteoporosis must be initiated in childhood, because the immature skeleton is more responsive to physical loading. Exercise recommendations for bone health promotion must consider the effects of loading not only on the more traditional measures of bone mineral content and macroarchitecture, but also on the microarchitecture and structural properties of the skeleton. The latter requires high precision 3D methods like quantitative computed tomography and magnetic resonance imaging.
Prospects Imaging resolutions used most commonly in exercise studies of children have sufficient precision to assess bone density and gross geometry. However, they remain insufficient to clearly depict and quantify the trabecular bone microarchitecture in vivo in humans.
