Brief Summary:
Doxorubicin and epirubicin are part of the class of chemotherapy agents called anthracyclines that are commonly used to treat breast cancer. Although these treatments work well against the tumor, they are known to cause damage to the heart muscle, resulting in diminished heart function that can be permanent, and may also damage the blood vessels and skeletal muscles. The purpose of this study is to determine whether short-term application of these interventions with specific timing relative to the receipt of each treatment can prevent the negative effects of anthracycline treatment on the heart, aorta (largest artery leaving the heart), and skeletal muscle, improve quality of life and reduce tumor size. Fifty-six early stage breast cancer patients who will receive anthracycline treatment will be randomly assigned to 1 of 3 groups who will: 1) perform a single 30-minute aerobic exercise session 24 hours prior to each treatment; 2) eat a diet consisting of 35% less calories for 48 hours prior to each treatment; or 3) receive usual cancer care. Magnetic resonance imaging (MRI) will be used to precisely measure the function of the heart, aorta, and the lower leg skeletal muscle at rest, and again during exercise to allow detection of more subtle signs of damage. We will also measure exercise capacity (i.e. aerobic fitness), microscopic damage to the heart muscle cells, a marker released into the blood in response to anthracycline-related heart damage, tumor size in patients receiving chemotherapy before surgery, quality of life and fatigue. These measures will be performed before treatment, at the end of treatment and 1 year later.

Arm Intervention/treatment
Experimental: Aerobic exercise
The exercise arm includes a single bout of supervised treadmill walking scheduled such that it would end approximately 24 hours prior to each of the participant's scheduled anthracycline treatment time.
Other: Aerobic exercise
The supervised exercise session will consist of a 10-minute warm-up, 30 minutes performed at 70-75% of heart rate reserve, which corresponds to a vigorous intensity, followed by a 5-minute cool-down

Experimental: 50% caloric restriction
The caloric restriction arm will restrict their total caloric intake by 50% for 48 hours prior to each anthracycline treatment.
Dietary Supplement: 50% caloric restriction
Meals mimicking participant dietary preferences and matching North American macronutrient guidelines will be provided consisting of 50% of total caloric intake for 48 hours

No Intervention: Usual care
The usual care arm will be asked to maintain their typical exercise and diet throughout treatment.



Primary Outcome Measures :
  1. Change in left ventricular ejection fraction reserve (peak exercise - rest) [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Cine steady-state free precession contiguous short axis slices will be taken at rest and at peak exercise using a resisted stepping device with a 3 T MRI scanner


Secondary Outcome Measures :
  1. Change in aortic stiffness reserve (peak exercise - rest) [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Radial imaging will be used at rest and peak exercise using a resisted stepping device with a 3 T MRI scanner

  2. Change in skeletal muscle oxygen consumption reserve (peak exercise - rest) [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Susceptometry-based oximetry using deoxyhemoglobin as an intrinsic contrast agent, coupled with phase contrast imaging for simultaneous measurement of lower leg blood flow, will together yield oxygen consumption, which will be measured at rest and at peak exercise using a resisted plantarflexion device with a 3 T MRI scanner

  3. Change in skeletal muscle mass and quality [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Skeletal muscle mass of the leg will be measured using Dixon fat-water separation imaging method that yields separated water and fat images to quantify skeletal muscle and adipose tissue.

  4. Cardiac T1 [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    T1 mapping will performed in a mid-ventricular short-axis slice using saturation recovery single-shot acquisition (SASHA) pulse sequencing

  5. Change in NT-proBNP [ Time Frame: 0-14 days before first anthracycline treatment, 24 hours after 1st anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    NT-proBNP will be analyzed in serum using electrochemiluminescence sandwich immunoassays

  6. Change in peak oxygen consumption [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Peak oxygen consumption will measured using a maximal cardiopulmonary exercise test


Other Outcome Measures:
  1. Change in clinical tumor size [ Time Frame: Anytime prior to inititiation of chemotherapy, and within 1 month of completion of chemotherapy or as otherwise clinically indicated ]
    Clinical tumor size will be assessed using ultrasound in participants receiving neoadjuvant chemotherapy only

  2. Health-related quality of life [ Time Frame: 0-14 days before first anthracycline treatment, 1-3 weeks after completion of anthracycline treatment, one year after initiation of anthracycline treatment ]
    Health-related quality of life will be measured by the Functional Assessment of Cancer Therapy - Fatigue (FACT-F) questionnaire.

  3. Combined clinical end-point [ Time Frame: 5 years after completion of treatment ]
    cancer recurrence, cardiac events, hospitalizations, or mortality will be extracted from clinical records and combined into a clinical end-point
