Physical Activity in Reducing Metabolic Dysregulation (MetD) in Obese Latina Breast Cancer Survivors

PRIMARY OBJECTIVES: I. To determine the effects of a 6-month progressive combined training (PCT) program on metabolic dysregulation (MetD) in centrally obese latina breast cancer survivors (LBCS). SECONDARY OBJECTIVES: I. To determine whether improved physical fitness and health-related measures from a 6-month PCT program are associated with reductions in MetD in centrally obese LBCS. II. To determine whether MetD status and physical fitness can be maintained following a 6-month follow-up period and to establish predictors of exercise behavior in LBCS. OUTLINE: Patients are randomized to 1 of 3 groups. GROUP I (PROGRESSIVE COMBINED TRAINING \[PCT\]): Patients undergo supervised exercise sessions comprising of aerobic exercise (AE) over 30 minutes and resistance exercise (RE) over 25 minutes 3 days per week for 24 weeks. Patients are encouraged to complete AE at home over 20 minutes 1 day per week. Patients receive a Polar heart rate monitor to monitor heart rate during the AE sessions. GROUP II (PROGRESSIVE AEROBIC TRAINING \[PAT\]): Patients undergo supervised exercise sessions comprising of AE over 45-60 minutes 3 days per week for 24 weeks. Patients are encouraged to complete AE at home over 20 minutes 1 day per week. Patients receive a Polar heart rate monitor to monitor heart rate during the AE sessions. GROUP III (USUAL CARE): Patients undergo usual care. Beginning 24 weeks, patients may undergo supervised exercise sessions comprising of AE and RE as in Group I. After completion of study, patients are followed up at 37 and 49 weeks.
