Exergaming Intervention and Breast Cancer Biomarkers in Black Women

Overview: This is a 6 month, two-arm randomized clinical trial using comparing exergaming to a control group. The investigators will randomize Black sedentary overweight/obese women to Wii Fit exercise (n=50) or the control arm (n=50). Women in the Wii Fit exercise group will come to the Georgetown community-based exercise facility 3 days/wk. The control group will be asked to maintain their current daily activities and not to exercise for the duration of the study. Based on the investigators previous findings that women who engage in 75-150 mins/wk of brisk walking had an 18% decreased risk of breast cancer, the investigators will target this level of activity in the investigators intervention arm. Also, this 150 min/week of physical activity meets the current recommendations of the American College of Sports Medicine (ACSM) and the US Department of Health and Human Services for healthy individuals and is in line with recommendation of the American Cancer Society (ACS) for cancer prevention.
