Summary of the measurements performed at the proximal tibia level. A total of 19 tomograms were taken from the tibia plateau every millimeter (the first tomogram at the reference line), and 13 tomograms every 5 mm (the last tomogram at distance of 7 cm from the reference line). The densities of the metaphysis, the diametapysis, and the diaphysis were calculated from tomograms 7–8, 9–16, and 17–19, respectively. Moreover, an accelerometer was fixed on the skin at the same site to measure peak acceleration (parallel to the tibia axis) when the heel hits the ground during a running session.
