NCT03980626

Brief Summary

This pilot study tests the effects of aerobic exercise training on cognitive function in breast cancer survivors (BCS). Participants will be randomized to a 12-week walking intervention or usual care. Walking participants will attend small group sessions led by an exercise specialist 3 times weekly. Usual care participants will complete baseline and post-testing and be offered two sessions with an exercise specialist. All participants will complete a fitness test, electrophysiology, and patient-reported outcomes at baseline and post-intervention. A subset of participants will also be invited to undergo magnetic resonance imaging (MRI). The investigators will generate preliminary data on clinical and biological correlates of exercise and cognition, including treatment protocol, cardiorespiratory fitness, brain structure and function, and cancer-related fatigue.

Study Arms (2)

Walking Intervention

EXPERIMENTAL

Walking participants will engage in the 3-times weekly walking program for 12 weeks.

Behavioral: Walking

Usual Care

NO INTERVENTION

Usual care participants will be offered two personalized exercise sessions with a trained exercise specialist after all post-intervention data have been collected.

Interventions

WalkingBEHAVIORAL

The exercise intervention is designed to improve cardiorespiratory fitness, a known correlate of cognition and brain health, and follows the American College of Sports Medicine exercise guidelines for cancer survivors. Participants will engage in small group, moderate-to-vigorous intensity walking sessions three times weekly. Sessions will begin with a warm-up and end with a cool down and be progressive in nature. Volume of exercise will increase across weeks such that participants will progress from 15-20 minutes of walking to 40-45 minutes by week 8, and from 40-55% of their estimated heart rate reserve (HRR) to 65% of their HRR by week 9. All sessions will be led by trained exercise specialists to ensure close monitoring of participant safety. Participants will wear heart rate monitors and be asked to rate their perceived exertion to ensure they are exercising within the prescribed range. Modifications to each participant's exercise prescription will be made as needed.
