Do the Effects of Exercise on Breast Cancer Vary With Environment

Abstract

We propose to study i6 healthy postmenopausal women who normally exercise. We will ask these women to have their blood drawn before and after an hour of exercise outdoors on a sunny day and then a week later indoors on a treadmill in a room with only indoor lighting. We propose that exercise done outdoors will have a different effect on vascular endothelial growth factor (VEGF), hypoxia inducible factors 1 alpha and beta, vitamin D activity, and estrogen metabolism as measured by the ratio of 2 hydroxyestrone and l6 alpha- hydroxyestrone. Elucidation of indoor versus outdoor influences on exercise induced metabolism may be important in understanding variations in reports of the protective nature of exercise on breast cancer prevention.
