The effects of cardiorespiratory fitness, physical activity and sedentary behavior on insulin resistance among breast cancer survivors being treated with anti-estrogen endocrine therapies.
Specific Aim 1: Examine the association between cardiorespiratory fitness and glucose tolerance/insulin sensitivity in breast cancer survivors treated with endocrine therapies. Specific Aim 2: : Examine associations between sedentary behavior, light, moderate and vigorous physical activity, and glucose tolerance/insulin sensitivity in breast cancer survivors treated with endocrine therapies.
