Influence of Exercise on Neurocognitive Function in Breast Cancer
In Brief
A clinical study evaluating Moderate-Intensity Aerobic Exercise Intervention for Breast Cancer. Completed, enrolled 153 participants across 1 site.
Detailed Summary
This randomized control trial will examine whether a well-controlled and monitored exercise intervention improves cognitive function in postmenopausal women with early-stage breast cancer and will explore whether neuroimaging metrics of brain health, pro-inflammatory biomarkers and symptoms (fatigue, sleep problems, depression, anxiety) mediate the effects of exercise on cognitive function. Furthermore, the study will explore whether the magnitude of the improvements in cognitive function are modified by estradiol levels.

Timeline
Interventions
The intervention is moderate-intensity aerobic exercise. Walking on a motorized treadmill will be the encouraged mode of exercise; however participants may use other equipment or home exercise. Participants will begin by exercising 10-15 minutes for 3 days/week during the first 2 weeks and gradually increase the duration for the following 4 weeks until they reach 40-50 minutes per session/3 days per week. This level is then maintained for the remainder of the 6 months. The rate of increase will be tailored based on baseline cardiorespiratory fitness and response to exercise. All sessions start and end with a vital sign check (in-person) and 5-10 minutes warm-up/cool-down. Trained exercise physiologists will supervise all exercise sessions and closely monitor adherence, intensity, and safety when sessions are completed in-person, or through regular communication when home-based exercise is warranted (due to COVID-19).
