Bone Properties Following Exercise Induced Changes in Insulin Sensitivity in People With Type 2 Diabetes

Diabetes mellitus type 2 is associated with low bone turnover and increased risk of bone fractures. Bone mineral density, however, is increased and cannot explain the increased fracture risk per se. The pathophysiology is not completely understood, but the decrease in bone turnover is believed to cause an accumulation of microcracks in bone tissue leading to bone fragility. The decrease in bone turnover may arise directly from insulin resistance or indirectly through formation of advanced glycation end-products. The main aim objective is to investigate how increases in insulin sensitivity following 12 weeks of moderate intensity bike exercise affect biochemical bone turnover markers and biomechanical bone properties in individuals with diabetes mellitus type 2.
