The purpose of this study was to examine the impact of aerobic exercise and low calorie diet on bone mineral density (BMD) as well as anthropometric measures (weight, body mass index, waist/hip ratio) among older women who are obese. Participating were sixty overweight senior women, ages 60 to 70 years old, who were allocated into two equal groups at random. Group A comprised 30 patients who were directed to adhere to low calorie diet while being closely monitored by medical professionals. Group B comprised 30 patients who were instructed to adhere to an exercise regimen in conjunction with low calorie diet. Anthropometric measures (weight, height, BMI, waist/ hip ratio) as well as BMD of the femur, the measurements were obtained at the onset of the research and 12 weeks later (post study). The participants engaged in aerobic workouts for a duration of 30-45 minutes by walking on a treadmill at a moderate intensity level, specifically targeting 70-85% of their maximal heart rate. Results: there were no substantial differences (p> 0.05) among the characteristics of both groups pre study. Post study the findings indicated a substantial decrease (p< 0.05) in anthropometric measures (weight, BMI, waist/ hip ratio) in both groups with greater reduction in group B. The BMD did not show a significant improvement in group A, however in group B, there was a substantial improvement in BMD. conclusion: In obese older women, the combination of aerobic exercise and low calorie diet resulted in weight reduction, decreased BMI, and reduced waist/hip ratio. This approach also had a sustained effect on BMD when compared to using a diet alone through a period of 12 consecutive weeks.
