Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Feasibility will be assessed by 1) the number of women that complete the 3--month program; 2) the number of women that can achieve the targeted amount of physical activity per week by the end of the program; and 3) the median amount of physical activity achieved group by all subjects that complete the program.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Weight Loss Intervention Group

Participants will take part in supervised exercise and home-based exercise sessions. Participants will be asked to follow a specific diet. Participants will be asked to take part in weekly behavioral group phone calls.

Group Type EXPERIMENTAL

Supervised Exercise

Intervention Type BEHAVIORAL

Participants will take part in supervised exercise activities two times per week at a YMCA. Length of the activity will be increased during participation in study. Participants will start at 40 minutes per week and work their way up to 120 minutes per week.

Home-based Exercise

Intervention Type BEHAVIORAL

Aerobic exercise activities to be completed at home. Participants will be asked to start out doing 60 minutes at home and work up to 180 minutes of purposeful aerobic home exercise per week.

Group Phone Calls

Intervention Type BEHAVIORAL

Once weekly phone calls that are group-based. The calls will discuss lifestyle changes specific to participants and cover the effects of diet, physical activity, and weight on breast cancer risk, as well as body image and emotional eating.

Diet

Intervention Type BEHAVIORAL

Participants will consume a nutritionally balanced, reduced calorie diet as recommended by the Academy of Nutrition and Dietetics.
