Abstract:
BACKGROUND:More than 50% of patients with diabetes are accompanied by osteoporosis. Exercise is the main method to treat diabetes, but whether it has an impact on diabetes osteoporosis is unclear.
OBJECTIVE:To analyze the different exercise intensities and changes in bone mineral density in type 2 diabetic rat models.
METHODS:Forty rats were randomly divided into model group and low-, medium-and high-intensity exercise groups. Al rats received intraperitoneal injection of streptozotocin to establish models of type 2 diabetes. Rats in the low-, medium-and high-intensity exercise groups did treadmil training at 10, 20, 30 m/min, 1 hour per day, 6 daysas a cycle. They had a rest for 1 day after each cycle, for 8 consecutive cycles. Rats in the model group did not do any exercise.
RESULTS AND CONCLUSION:Compared with the model group, the weight of rats was decreased; blood glucose levels were reduced;osteocalcin and serum calcium levels and biomechanical indexes of femur increased; serum phosphorus and alkaline phosphatase decreased in the low-, medium-and high-intensity exercise groups. Bone mineral density increased in the medium-and high-intensityexercise groups. These findings confirmed that different exercise intensitieshavea certain influence on bone mineral density and bone metabolism in type 2 diabetic rat models. When using a method of treating movement, proper physical exercise can increase serum osteocalcin content, improve bone metabolism, prevent diabetic osteoporosis, and have a high clinical value.
