165Background: Metabolic syndrome (MetS) has been reported higher in breast cancer survivors (BCS) compared to age-matched postmenopausal women. The risk for cardiovascular disease and diabetes is significantly increased in women with MetS. Lifestyle behaviors are recommended first line interventions to reduce risk for MetS. Methods: From a 12 month randomized controlled trial (RCT) of a fitness center exercise intervention compared to a home physical activity group, the criteria for MetS (3 of 5 components: waist circumference [WC] ≥ 80cm, triglycerides ≥ 150mg/dL, HDL cholesterol 100mg/dL) were used to identify BCS with MetS. General estimating equation was employed for longitudinal changes. Heart rate recovery (reduction in heart rate from peak heart rate at one minute after exercise stress test) was used as a measure of cardiovascular fitness. Pearson correlation coefficients assessed associations between heart rate recovery an...
