The purpose of this study was to investigate the effects of low󰠏intensity resistance training with blood flow restriction on serum VEGF, bone markers and bone mineral density in elderly women. [Methods] The subjects were divided into three groups: low-intensity resistance training with blood flow restriction(BFR󰠏LRT, n=8); high intensity resistance training(HRT, n=8); low-intensity resistance training (LRT, n=5). Both the BFR󰠏LRT and LRT groups worked out knee extension and leg curl exercises

[Results] As a result after 12 weeks, serum VEGF level have increased significantly among BFR󰠏LRT group compared to HRT and LRT groups. Serum Bone ALP level have increased significantly among BFR󰠏LRT and HRT groups compared to LRT group. Calcaneus BMD have increased significantly among BFR󰠏LRT and HRT groups compared to LRT group. [Conclusions] In conclusion, despite using low-intensity load, BFR󰠏LRT is a efficient training alternative to HRT for improving bone metabolism in older women.
