The primary aim of this study is to compare the acute glycemic effects of two novel, alternative physical activity (PA) strategies (dispersed post-meal PA, PA snacks) to a no PA condition and to exercise sessions representing the PA guidelines (standard 30-minute walking bout performed under fasting and under postprandial conditions and a standard 30-minute resistance training session) among sedentary breast cancer survivors who are currently receiving hormone therapies and age- and BMI-matched postmenopausal women without a history of cancer. The secondary aim is to determine whether the alternative PA strategies are acceptable and feasible in the free-living setting. An exploratory aim is to determine whether the outcomes differ between women with and without a history of breast cancer and use of aromatase inhibitors. The investigators hypothesize that: 1. Dispersed PA and PA snacks will result in greater reductions in 24-hour glucose and postprandial glucose compared to the no-PA baseline and similar reductions to a standard 30-minute bouts of walking; 2. The alternative PA strategies will be more feasible and have greater acceptability by cancer survivors compared to the standard 30-minute bout of walking or resistance training; and 3. The different PA strategies will have similar effects on glycemic outcomes for both breast cancer survivors and cancer-free controls. The resistance exercise session is an exploratory trial as the effects of it on acute glycemic control a…
