Purpose- To examine the effects of aerobic exercise intensity on body composition and lipidprofile changes in Method- Forty-Five middle-aged; obese/overweight women(age:25-40yearsand BMI≥25-30kg/m2) completed one-of-three-10 week aerobic exercise interventions:1)Moderate exercise training(45- 50%HRRmax); 2)intensity aerobic exercise(70-75%HRRmax); 3)no exercise training(control).Participants exercised 3days.week-1for 10 weeks per session 60 minutes. The intensity ofaerobic exercise were controlled by lunch caliper and measurements of body composition andserum lipid profile indices in per and post test.Results-Moderate and intensity aerobic exercise has a significant changes on weight(p<0/000);fat percent(p<0/04); BMI(p>0/001); fat weight(p<0/003); lean body weight(p<0/02);WHR(P<0/000); HDL(P<0/000) in patients. The differences between groups were specializedby Sheffe test.Conclusions-The present data indicate that body composition and lipid profile changes areaffected by intensity of aerobic exercise training for reducing weight; fat percents; BMI; fatweight; lean body weight; WHR; HDL in obese/overweight women
