Summary
Brief summary (as posted)
The purpose of this study is to demonstrate the feasibility of assigning breast cancer survivors currently receiving chemotherapy to exercise at a specific time of day, e.g., morning or afternoon/evening, for a 4-week exercise intervention. Information gathered from this study will help inform a future, larger trial. Study Aims: 1\. Assess the feasibility of engaging in exercise at an assigned time-of-day (e.g., morning or afternoon/evening) in breast cancer survivors on chemotherapy. Hypothesis: Assigning windows of time within the day to complete exercise (e.g. 5-10am exercise start time vs. 3-8pm exercise start time) will be feasible among this patient population. 1a. Determine the acceptability engaging in exercise at an assigned time-of-day (e.g., morning or afternoon/evening) in breast cancer survivors on chemotherapy. Hypothesis: Engaging in exercise at an assigned time-of-day will be acceptable in this patient population. 2\. To generate evidence on the magnitude of the effect sizes and outcome variability of physical function and human performance variables. Tests to be conducted at baseline and end of study to measure physical function and human performance variables include: Timed up and go test, 30-second chair stand, handgrip strength, cardiorespiratory fitness.
