The Effect of Aerobic and Combined, Aerobic-anaerobicexercise on Obese Diabetic Patients

Abstract Background Physical exercise is has been recommended as an important non-pharmacological therapeutic strategy for managing diabetes type2 mellitus (T2DM) and obesity. The purpose of this study was to compare the effects of17 weeks aerobic, and combined, both aerobic plus resistance training on HbAlc, bodyweight, body composition and others cardiorespiratory fitness (CRF) components among T2DM and obese patients. METHODS: positivism style of research paradigms and quantitative method of true randomize experimental design was used. 30 T2DM and obese male patients; aged 40–65 years (M=54.4, SD=6.96593), their BMI ≥30 kg/m2 _ 39.9 kg/m2, were randomized to one of the two exercise interventions or a control group. All two exercise groups had an equal total exercise time lasting 60min aerobic or combined training (50-70% of MHR & 1RM). HbAlc, body mass index (BMI) Total cholesterol (TC), Triglycerides (TG), High-density lipoprotein (HDL-C), Low density lipoprotein (LDL) and Waist circumference (WC) were measured. Paired sample T-test, Analysis of Variance (ANOVA) and post Hock was used. RESULTS: aerobic and combined groups showed significance improvement during pre and posttest in weights, BMI, HbAlc, TC, TG, LDL, HDL and WC, P <.001, than the control group. From the ANOVA (Post Hock) result: Aerobic training and combined group was revealing a greater statistical difference more than the Control group in weight (MD = -9*, and MD = -7* p < 0.05), BMI (MD= -3.68* and -2.99* , P< .001), HbAlc (MD = -8.17*, and MD= -8.61*, P < 0.001), TC (MD = -34.4*and MD= -40.6*, P < 0.001), LDL (MD = -47.3*, and MD = -43.2*, P < 0.001),WC (MD = -12.1*, and MD= -15.4*, P < 0.001), TG (MD = 73.2*and MD= -82.4*, P < 0.001). But in HDL the aerobic group didn’t shown significance difference (MD= -.2, p = .969 that is P > 0.05) than the control group. But the combined group was shown great statistical difference than the aerobic and control group with (MD= 6.4*, P< .001) and (MD= 6.2*, p < .001) respectively. Conclusion: Compared to aerobic exercise, a 17-week of combined aerobic-anaerobic exercise intervention was more successful in altering these parameters.
