Background: Prediabetes is a condition that comes before type 2 diabetes with Glycated hemoglobin (A1C) of 5.7%- 6.4%, Fasting blood glucose of 100-125 mg/dl, without intervention is likely to become type 2 diabetes in 10 years or less. Exercise intervention was generally found to reduce glycated hemoglobin and prevent or delay type 2 diabetes. Purpose: The purpose of this study was to investigate and compare the effectiveness of aerobic versus resisted exercise on Glycated hemoglobin (HbA1c) in prediabetics. Subjects: Thirty subjects with HbA1C (5.7-6.4) were selected from the out clinic of Damietta specialized hospital with age ranging from (25-45years). They were randomly divided into 3 equal groups; aerobic group (A), resisted group (B) and control group (C). Procedure: Group A received aerobic exercise with intensity 60-75% of Maximum Heart Rate, 30-40 min duration. Group B received resisted exercise with moderate intensity 60-75% of Repetition Maximum. Group C control group. For all groups treatment conducted for 3 months, 3 times per week, day after day. HbA1c and Fasting blood glucose (FBG) were measured before and after 3 months of the treatment. The Results: Results revealed that, there was a significant reduction of glycated hemoglobin and fasting blood glucose in both groups (A and B) (P<0.05). Comparison between groups post treatment showed that there was no significant difference of the mean values fasting blood glucose and HbA1c between (group A and B) with (p=1.00) (p=0.29). While, there was significant difference among (group A versus C), and (group B versus C) with (P=0.03 and P=0.004) (P=0.002 and P=0.000) in favor for group (B). Conclusion: It could be concluded that, both aerobic and resisted exercise could be effective in prevention or delaying of type 2 diabetic but resisted may be more effective
