Abstarct: The purpose of this study was to compare the effects of combined (aerobic and resistance) exercises on heart rate variability (HRV) and anthropometric indices in overweight and obese women compared to normal-weight women. This quasi-experimental study was conducted using a pretest-posttest design with a control group. Thirty young women (15 overweight/obese and 15 normal-weight) were selected via convenience sampling. The exercise intervention consisted of 8 weeks of combined training, performed three sessions per week, including aerobic exercise at 60–75% HRmax and resistance exercise at 60–70% 1RM (3 sets × 10–15 repetitions). HRV indices (SDNN, RMSSD, LF, HF) and anthropometric indices (BMI and body fat percentage) were measured before and after the intervention. The results showed that combined training significantly improved HRV and reduced BMI and body fat percentage in both groups, but the magnitude of improvement was greater in the overweight and obese women. These findings suggest that combined exercises can be recommended as an effective intervention to enhance cardiovascular health and body composition, particularly in overweight and obese women
