Comparative results from studies that used high resolution peripheral quantitative computed tomography (HR-pQCT), measured 3 days post-bed-rest. The % change in total, cortical and trabecular density from pre-bed rest values is displayed at the distal tibia and radius

CON control group, RVE resistive vibration exercise, RE resistive exercise, LBNP TM lower body negative pressure treadmill

* Indicates p < 0.05 compared to baseline, ** indicates p < 0.01 compared to baseline, ~indicates p < 0.001 significance between baseline (analysis of variance testing), ^ indicates p < 0.05 significance between exercise and control groups (analysis of variance testing). For the group column, n is the number of people in each study arm
