The effect of 8 weeks of Circuit Resistance Training on Glycaemic control and body composition in women over age 50 with diabetes mellitus type 2

Introduction: The prevalence of type 2 diabetes mellitus (T2DM) increased significantly in the last three decades, and effective strategies to manage and prevent this disease are urgently needed. Physical activity and exercise training is a way effective for glycaemic control in type 2 diabetes mellitus (T2DM) patients. However, the effect of Circuit Resistance Training (CRT) program on patients T2DM are unknown. The purpose of this study was to investigation the effect of 8 weeks of Circuit resistance training (CRT) on glycaemic control and body composition in women over age 50 with T2DM. Methods: Twenty women over 50 years old with diabetes Referred to diabetes Canter of 17 Shahrivar hospital in Amol were divided randomly into two groups; Circuit resistance (n=10) and Control (n=10). Resistance training consisted of 10 stations for 8 weeks and 3 sessions per week (Intensity 60-80% 1RM). Levels of Lipid profile and body composition before and after eight weeks Training in both groups were measured. Statistical analysis of the data was carried out by SPSS (v. 22). Results: Fasting blood glucose (FBG) levels (P=0.021) and serum insulin (0.032) significant decreased in CRT. HOMA-IR was calculated from FBG and serum insulin so was observed decreased in HOMA-IR levels (P=0.04). Also after 8 weeks circuit resistance training, BMI (P= 0.003), WHR (P=0.004) and body fat present (0.019) significant decreased in CRT. Conclusion: According to our results, CRT was ans effective approach to improve the Anthropometrics, FPG, serum insulin, and HOMA-IR in women over age 50 with diabetes mellitus type 2. Moreover, CRT did شhave influence on the glycaemic control and body composition.
