This study was conducted to determine the effect of different exercise intensities on leptin hormone and insulin resistance in obese postmenopausal women. Forty five healthy obese postmenopausal women with age ranged from 50 to 60 years. Were selected randomly from the Out Patient Clinic of the National Nutrition Institute; their body mass index (BMI) were {u2265}30 kgs/m².Women were randomly assigned into three groups (A&B&C) each group consisted of fifteen women. Group (A): Each woman followed a diet regimen for weight reduction for 12 weeks. Group (B): Each woman followed a diet regimen as the same as in group (A) in addition to program of aerobic exercise in form of cycle ergometer for 25 minutes three sessions per week for 12 weeks. Group (C): Each woman followed a diet regimen as the same in group (A) in addition to regimen protocol of low volume high intensity interval exercise on cycle ergometer for 25 minutes three sessions per week for 12 weeks. Evaluations of all groups (A&B&C) were done before initiation of treatment and after the end of treatment (12 weeks) through measuring the anthropometric measurements, body composition measurements and lipid profile. In addition to assessment of the insulin resistance value and leptin hormone. Results: Showed that there was a statistically highly significant decrease in the body weight, BMI, Fat percentage, and fat mass, insulin resistance and leptin hormone in all groups (A&B&C) between before initiation of treatment and after the end of treatment, but group (C) had greater improvement more than group (B) and group (A), while the WC and android / gynoid ratio revealed that a statistically significant decrease in group (B) and group (C), but changes in the group (A) were not statistically significant. There was also a statistically significant increase in fat free (g) at group (C) while a statistically significantly decrease in group (A), but there was statistically non significant changes occur in group (B)
