“OBJECTIVE: To analyze the effects of concurrent training on body composition in postmenopausal women with and without the use of aromatase inhibitors for breast cancer treatment. METHODS: We evaluated 85 women, aged between 50 and 80 (63,16 ± 8) years, residents in the city of Presidente Prudente, São Paulo, Brazil. The sample consisted of four groups: Training group with cancer (TGC, n= 22); Training group without cancer (TGWC, n=36); Control group without cancer (CGC, n=17); Control group with cancer (CGWC, n=10). Body composition was estimated by DEXA (Dual Energy X-Ray Absorptiometry). The training protocol consisted of 50 minutes of resistance training followed by 30 minutes of aerobic training, three times a week, during three months. It was used the paired t test to compare each group pre and post three months of intervention. All analysis were performed using SPSS version 18.0, with significance level set at 5%. RESULTS: It was observed that the groups TGC and TGWC had an increase in lean body mass leg (p = -0.001; p = 0.022), and total lean body mass (p = 0.022; 0.469), respectively. These groups also presented a decreased in fat mass legs (p = 0.013; p = 0.011); fat mass arms (p = 0.038; p = 0.081) and a decreased total fat mass (p = 0.036; p = 0.001). The control groups did not show statistical difference on the variables of body composition. Conclusion: Three months of concurrent training was able to promote significant improvements on the body composition of postmenopausal breast cancer women undergoing hormone therapy with aromatase inhibitors.Key words: breast cancer; postmenopausal women; concurrent training; body composition.
