Abstract Background: Obesity has been linked to development of diabetes mellitus, cardiovascular diseases, dementia, and cancers. Specifically in accumulation of abdominal visceral adipose tissue were related to difference in metabolic profile and indicator of cardiovascular disease risk in postmenopausal women. Aim of Study: Was to determine the effectiveness of ultrasound cavitation versus abdominal exercises on post-menopausal abdominal fat. Material and Methods: Sixty obese women with abdominal fat, their age ranged from (50-65) years, their BMI (30- 35kg/m2), WHR ranged between (0.81 to 1.0). They were selected from Outpatient Clinic of physical therapy department in Egyptian Radio and TV Union. They were randomly divided into two equal groups. Group (A) consisted of 30 women who received ultrasound cavitation in addition to low-calorie diet (1200cal) for eight weeks, two sessions per week, Group (B) consisted of 30 women who received abdominal exercises in addition to the same low-calorie diet (1200cal) for eight weeks, two sessions per week. All women in both groups (A&B) were evaluated by measuring (BMI,WHR and Skin fold thickness) before and after the study period. Results: The results showed high statistical significant decrease in the mean values of BMI, WHR and Skin fold thickness in both groups, However the results were in the favor of abdominal exercises group. Conclusion: So, it could be concluded that both ultrasound cavitation and abdominal exercises combined with low-calorie diet were effective in reduction of BMI, WHR and skin fold thickness, However the abdominal exercises combined with low-calorie diet cause much more improvement than ultrasound cavitation.
