beta-trialThe Breast Cancer and Exercise Trial in Alberta (BETA Trial) is a randomized controlled exercise intervention trial. Dr. Friedenreich and her colleagues recruited 400 postmenopausal women aged 50-74 years of age  to examine how a one-year high volume (300 minutes per week) versus moderate volume (150 minutes per week) aerobic exercise intervention influences and modifies biomarkers for breast cancer risk. The main biomarkers to be examined include changes in body fat levels, insulin and insulin resistance, inflammation and endogenous sex steroid hormones. The outcomes will help determine what volume of exercise will have the most benefit in reducing these biomarkers that are associated with increased breast cancer risk in postmenopausal women.
