The effect of a combined exercise course on physical fitness, cognitive function and glycemic control in women with type 2 diabetes

Background & Aim: Type 2 diabetes is one of the most common endocrine disorders, which can include Lack of blood sugar control, multiple cardiovascular problems, and decreased cognitive function . The aim of this study was to investigate the effect of a combined exercise course physical fitness, cognitive function and glycemic control in women with type 2 diabetes. Methods: 21 female participants with type 2 diabetes were randomly divided into training (12) and control (9) groups.The combined exercise training program included aerobic, resistance and balance training that were performed for 12 weeks (3 sessions per week). Before and after the training period, fasting blood samples were taken from all subjects to measure serum HbA1c and glucose. Also, VO2max, static and dynamic balance and upper and lower body muscle strength were measured. Cognitive function was assessed using Digit symbol substitution and Forward digit span tests. Data were analyzed using repeated measures analysis of variance at the significant level of P <0.05. Results: Glycosylated hemoglobin and glucose levels in the intervention group showed a significant decrease compared to the control group. Except for static balance in the experimental group, physical fitness improved significantly compared to the control group. Cognitive function did not show a significant change between the two groups.  Conclusion: Combined exercise can improve fitness and glycemic control in women with type 2 diabetes. These training have no effect on cognitive function.
