The Effect of 8 Weeks Resistance Training on Bone Mass Density in Postmenopausal Women with Type 2 Diabetes

Studies has shown that diabetes type 1 and partly type 2 may exacerbate osteoporosis. The aim of this study was to determine the effects of 8 weeks resistance training on Bone Mass Density (BMD) in postmenopausal women with type 2 diabetes. 20 postmenopausal women with type 2 diabetes were recruited from Sanandaj diabetes association, (mean age, height, weight and BMI = 51±6 yr, 153.4±5 cm, 68.3±11 kg and 29.3±4 kg/m2, respectively) and then randomly divided in two groups including experimental and control. The experimental group performed resistance training for 8 weeks, three sessions per week and each session with 70% of one repetition maximum. The resistance training program consists of: bench press, leg extension, shoulder press, hamstring curl, standing two-arm curl and lat pull down. During the same period, the control group did not participate in any regular exercise training, but in terms of medication and dosage it was similar to the experimental one. Densitometry was performed to assess bone mass density (BMD) of the femur, distal forearm, and lumbar spine. After 8 weeks, there werent any significant changes in BMD [femoral neck (p=0.72), lumbar spine (p=0.36) and forearm bone (p=0.8)] in groups and bone sites. In addition, no significant differences were found between the two groups (p values for the femoral neck, lumbar spine and forearm were 0.18, 0.23 and 0.67, respectively). Discussion & These data indicate that 8 weeks resistance training did not improve Bone Mass Density in postmenopausal women with type 2 diabetes.
