High-Intensity Interval Training Is Feasible in Women at High Risk for Breast Cancer.

ABSTRACT: PURPOSE:This trial aimed to demonstrate the feasibility of high-intensity interval training (HIIT) in postmenopausal, overweight/obese women at high risk of invasive breast cancer and to explore HIIT on changes in cardiorespiratory fitness (CRF), body weight, and body mass index (BMI) compared with moderate-intensity continuous training (MICT) and usual care (UC). METHODS:Forty-four women were randomized to HIIT, MICT, or UC for a 12-wk, thrice weekly, supervised exercise intervention. HIIT included a 5-min warm-up at 50%-70% HRpeak, four cycles of 4 min at 90%-100% HRpeak, followed by 3 min at 50%-70% HRpeak. MICT consisted of 41 min at 60%-70% HRpeak. Feasibility was assessed by consent, adherence, compliance, and retention rates. CRF, body weight, and BMI were measured at baseline and e
