Effects Of Community-based Supervised Exercise In The Body Composition And Strength Of Breast Cancer Survivors: 1778 Board #372 May 28 9:30 AM - 11:00 AM

PURPOSE: To analyze the effects of a low-cost community-based supervised exercise program on body composition and muscle strength in breast cancer survivors. METHODS: Twenty-one female survivors of breast cancer concluded a single-arm clinical trial with a control and an experimental phase. Each participant was evaluated in 5 consecutive moments: 16 and 8 weeks before intervention (M1 and M2), immediately before intervention (M3), and 8 and 16 weeks after the exercise program started (M4 and M5). Participants benefited from conventional care during the control phase (M1 to M3) followed by a community-based exercise program (M3 to M5). This consisted of 3 sessions per week of 60-min combining aerobic and strength exercise at moderate to vigorous intensity in group classes of no more than 20 participants with low-cost material. Body mass index (BMI), handgrip strength and sit-to-stand (STS) test were assessed in all the evaluation moments. RESULTS: There were significant increases through time in handgrip strength in both surgical and non-surgical upper limbs (p<0.0001) and in lower limbs functional strength (p<0.0001) (table). BMI increased during control phase and decreased during the initial phase of exercise training program (p=0.050). Serious adverse events were not reported. CONCLUSIONS: A low-cost community-based supervised exercise program is safe and improves body composition and strength in breast cancer survivors after primary treatment.Legend: Results were tested with repeated measures analysis of variance and are presented as mean±SD; Post-Hoc analysis were corrected with Bonferroni. Effect size was calculated as Partial Eta Squared.*Higher than M1; ** Higher than M1-M3; ***Higher than M1-M4; † Higher than M1-M2; ‡ Higher than M3; p<0.05.
