PURPOSE: To evaluate the effects of 24 weeks of Mat Pilates in breast cancer survivors (BCS) undergoing hormone therapy on lower and upper body muscle strength parameters and flexibility. MATERIALS AND METHODS: Forty-three BCS (>= 40 years) with confirmed breast cancer stage 0 to III undergoing hormone therapy were included. Participants were randomized into Mat Pilates (three times/week, 60 min session) or control group (relaxation activities every two weeks). The difficulty and number of exercise repetitions were increased over the weeks. Assessments were performed at three times points (baseline, 12 weeks, and 24 weeks). The generalized estimating equations (GEE) model was used to compare each outcome measure during the analysis of intention to treat (ITT) and "Per protocol analysis" (PPA). RESULTS: The Pilates group presented significantly increased (p < 0.05) isometric flexor-extensor PT, and concentric and eccentric flexor PT and mechanical work (MW) after the intervention. Most of the upper body strength parameters, time to achieve maximal force (TFmax), maximal force (Fmax), and rapid force index (RFI) and right-left upper and lower body flexibility (p < 0.05) also improved. CONCLUSIONS: From our findings, we conclude that 24 and 12-weeks of Mat Pilates induced strength and flexibility gains for lower and upper body, respectively.
