Phase 2 Trial of Adaptive Versus Standard Dosing of Aerobic Training in Patients Receiving Chemotherapy for Primary Breast Cance
In this study, investigators will compare standard Aerobic Training/AT with adaptive Aerobic Training/AT. Standard AT will be a fixed (unchanging) amount of walking each week, while adaptive AT will adjust the level of exercise depending on participants' response to the exercise. Investigators will see how both study approaches (standard AT and adaptive AT) affect participants' CRF.
• Aged ≥18 years
• Female
• Diagnosed with primary breast cancer as defined by one of the following:
‣ Histological confirmation
⁃ As per standard of care imaging
• Scheduled to receive neoadjuvant/adjuvant chemotherapy
• Performing ≤90 minutes of moderate- and/or strenuous-intensity exercise per week, as evaluated by self-report
• Willingness to comply with all study-related procedures
• Able to achieve an acceptable peak baseline CPET, as defined by any of the following criteria:
∙ Achieving a plateau in oxygen consumption, concurrent with an increase in power output;
‣ A respiratory exchange ratio ≥ 1.10;
‣ Attainment of maximal predicted heart rate (HRmax) (i.e., within 10 bpm of age-predicted HRmax \[HRmax = 220-Age\[years\]);
‣ Volitional exhaustion, as measured by a rating of perceived exertion (RPE) ≥ 18 on the BORG scale.
