Introduction: The burden of type 2 diabetes mellitus varies remarkably throughout the region of the world and is a serious public health problem in both developed and developing countries. Despite the advancement in knowledge and the increasingly effective therapeutic strategies for type 2 diabetes mellitus management, sustainable control rates at the population level are still elusive. Objective: To compare effect of aerobic exercise and progressive resisted exercise on glycosylated haemoglobin (HbA1c) persons with type 2 diabetes mellitus. Methodology: 450 participants (M - 275, F- 175) were enrolled in study. Group 1 participants have performed aerobic exercise for 8 weeks, Group 2 participants have performed progressive resisted exercise for 8 weeks, Group 3 participants were in control group. HbA1c, Fasting blood glucose (FBS), body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were outcome measures for the study. Results: ANOVA tests were applied found Fcal = 1.65 (p = 0.19) for HbA1c, Fcal = 1.91 (p =0.15) for FBS, Fcal = 5.79 (p = 0.003) for BMI, Fcal = 4.54 (p = 0.01) for WC, Fcal = 26.62 (p < 0.0001) for SBP and Fcal = 110.65 (p < 0.0001) for DBP. Conclusion: Aerobic exercise and progressive resisted exercise should be part of the management of type 2 diabetes mellitus as an adjunct therapy.
