DO - N2 - The aim of this study was to investigate the effects of 12 weeks of walking on plasma levels of leptin in postmenopausal women with breast cancer. Nineteen postmenopausal women with breast cancer (age: 55.05+2.7 years) who received surgery, chemotherapy and radiation-therapy and were receiving hormone therapy by letrozol were divided into two groups: control (N=8) and experimental (N=11). Subjects in the experimental group performed 12 weeks of an exercise program which consisted of 25 to 45 minutes of walking with an intensity of 45% - 65% of target heart rate, three times a week. In pretest and posttest, leptin, insulin, glucose, insulin resistance, anthropometric variables (body weight, BMI, WHR, and WC), body fat percentage and VO2peak were measured in both groups. Data were analyzed using ANCOVA (P UR - https://jsb.ut.ac.ir/article_23862.html L1 - https://jsb.ut.ac.ir/article_23862_5199876ccffbcafe7ddc764e2f049888.pdf ER -
