In this study, the investigators hypothesize that a high dose of post-workout protein after each exercise session will have greater improvements in changes in body composition, including muscle mass and percent body fat versus a workout alone.
Age 20-89 years
Women prescribed exercise as a SOC
Women with a biopsy proven diagnosis of ductal carcinoma in situ (DCIS) or invasive carcinoma of the breast
Women must have undergone treatment for breast cancer, including one or more of the following: surgery, radiation therapy, chemotherapy, immunotherapy, or hormonal therapy. Women undergoing active chemotherapy are not allowed on study. Immunotherapy or targeted agent usage is allowed.
Any current treatment with cytotoxic chemotherapy for breast cancer
Inability to safely engage in group sessions of resistance training as deemed by study PI
Severe arthritic, joint, cardiovascular, or musculoskeletal condition deemed by PI to be unsafe to engage in resistance training
Beta blocker or GLP-1 inhibitor medications
Parallel
Whey protein (60 grams)
Dietary supplement60 grams of whey protein
No protein
Other intervention0 grams of whey protein
Determine changes in pounds of muscle and fat mass after each exercise regimen
Determine changes in resting metabolic rate in calories per day at the completion of the exercise regimen
Determine changes in body composition at the completion of the exercise regimen, including body mass in pounds, fat mass in pounds, fat-free mass in pounds, % fat, and % fat-free mass
Determine changes in Y-balance score at the completion of the exercise regimen
Y-Balance score measures the length an individual can extend their foot. The larger the score the better the balance.
Functional Movement Screen (FMS) scores at the completion of the exercise regimen
FMS measures movement patterns with scoring from 0 to 21. The large the score the better the mobility.
