Background: Obesity is a global challenge due to the positive energy balance. Exercise training is one of the best methods for managing obesity and related disorders. The present study was conducted to determine the effect of tow types of High-Intensity Interval Training (HIIT) alone and Combined with Resistance Training (CHRT) on lipid profiles and glucose, insulin, and insulin resistance in overweight/obese middle-aged women.
 Methods: The present experimental research was performed on 24 middle-aged overweight/obese women divided into two homogeneous HIIT (5 days/week, n=12) and CHRT (3 days/week HIIT with 2 days/week resistance training, n=12) groups for ten weeks. The HIIT protocol consisted of alternating bouts of highintensity exercise at %85–%80 of VO2max with active breaks at %60 of VO2max and resistance training protocol conducted to a circuit-weight training with %80-75 of -1RM. Blood samples were collected 48 hours before and after the training period, and then the data were analyzed using SPSS. 
Results: The findings showed that the reductions of BMI and WHR were not significant in the HIIT group (p>05/0), but the percentages of body fat, cholesterol, TG, HDL, LDL, glucose, insulin and insulin resistance significantly decreased in both groups (p<05/0). WHR and lipid profiles were significantly different between the two groups (p<05/0), and the change level was greater in CHRT group.
Conclusion: The results of the current study showed that CHRT, through the dual effects of the compensatory mechanisms of both training methods, can better lead to weight loss and adjusted metabolic status in middleaged overweight/obese women compared with HIIT.
