Objective: Having serum levels of high cholesterol can cause life-threatening disease speciallycardiovascular problems. However, it is believed aerobic training can reduce the risk of cardiovasculardisease, but this effect varies considerably among exercise intervention studies. Therefore, the presentstudy was designed to evaluate the effects of aerobic training on serum levels such as cholesterol, highdensity lipoprotein, Low density lipoprotein, triglycerides and anthropometric parameters of inactivewomen.Materials and Methods: This study was performed as an experimental study, in which 20 healthy nonathletefemales(age 27.50 ± 4.11 yr, height 163.55 ± 4.22 cm, body weight 62.81 ± 4.66 kg) randomlydivided in two groups(Control group, n=10 and Experimental group, n=10). Blood samples were taken 48h before starting the aerobic training program. Then, experimental group performed a selected aerobictraining program with 65-85% of individual maximum heart rate for 3 session per week, 60 minutes persession and 6 consecutive weeks. Then another blood sample was taken following the training period.Serum levels of lipoproteins of all subjects before and after the training period were measured usingstandard biochemical methods. Differences between post test and pre test were evaluated using aStudent′s t-test for paired samples. A P-value < 0.05 was considered to be statistically significant.Results: Our results showed that the aerobic training caused significant changes(p
