| Abstract: | The aim of this study was to examine and compare the effects of different resistance training protocols on bone marker concentrations in older men. Thirty-seven healthy older male subjects were assigned to one of three groups: high-intensity resistance training (HI-RT, age?=?57.5?±?0.8); low-intensity resistance training with vascular restriction (LI-VRT, age?=?59.9?±?1.0); and control (CON, age?=?57.0?±?1.1). Blood samples were collected before and after 6?weeks of resistance training to measure the changes in bone formation bone alkaline phosphatase, (Bone ALP)] and resorption (C-terminal cross-linking telopeptide of Type-I collagen, CTX) marker concentrations. A significant main effect for time was detected in Bone ALP to CTX ratio for the exercise groups (p??LI-VRT, p?
