Overview

The goal of this clinical trial is to assess the feasibility of an 8-week aerobic exercise program and its effect on arterial function in breast cancer survivors. The main questions it aims to answer are: * Is an 8-week aerobic exercise program feasible in breast cancer survivors after the completion of chemotherapy, immunotherapy and/or anti-HER2 agents? * Is this 8-week aerobic exercise program beneficial for vascular function in breast cancer survivors? Participants will: * Begin an 8-week aerobic exercise program, three days per week, after the completion of chemotherapy, immunotherapy and/or anti-HER2 agents. * Visit our facility three times: before the exercise program, 1 month after, and after the completion of the program. * Complete questionnaires, physical functional tests, and body composition and vascular measurements at every visit.

Outcomes

Primary Outcomes

Enrollment (Recruitment rate)

Enrollment will be measured by the proportion of eligible breast cancer survivors who provide informed consent to participate in the study. The proportion of enrolled participants will be reported.

Time frame: From enrollment to immediately after first visit

Participant adherence - Proportion of people considered adherent

Adherence will be measured as the proportion of exercise sessions completed by consented survivors out of the total of 24 prescribed training sessions. Completion of at least 18 of the 24 training sessions will be considered adherent.

Time frame: From enrollment to the end of intervention at 8 weeks

Retention - Proportion of survivors who completed the study

Retention will be measured by the percentage of consented survivors that completed the research study compared to the total number initially enrolled. The proportion of survivors who completed the study will be reported.

Time frame: From enrollment to the end of intervention at 8 weeks

Pulse Wave Velocity

This test measures how stiff your arteries are (called pulse wave velocity). Pulse wave velocity is an important measure that can help predict the risk of heart and blood vessel disease. It is a simple, non-invasive test, which means it does not involve needles or anything that goes inside your body. We will use a device called the SphygmoCor XCEL to do the test. To measure this, we will place a small sensor on your neck (over the carotid artery) and a blood pressure cuff on your upper thigh (over the femoral artery). The cuff will inflate slightly while we record your pulse waves. We will also use a tape measure to find the distance between the two spots. This measurement will be conducted on three occasions: before the intervention begins (Visit 1), and after the 4th (Visit 2) and 8th (Visit 3) weeks of the intervention.

Time frame: From enrollment to the end of intervention at 8 weeks"

Aortic Blood Pressure

We will use a simple, non-invasive test to estimate the aortic blood pressure with a device called the SphygmoCor XCEL. The device measures your blood pressure using a cuff placed on your upper arm. Aortic blood pressure is another test we use to check the health of the heart and blood vessels. This measurement will be conducted on three occasions: before the intervention begins (Visit 1), and after the 4th (Visit 2) and 8th (Visit 3) weeks of the intervention.

Time frame: From enrollment to the end of intervention at 8 weeks

Secondary Outcomes

Blood Pressure

Participants will be asked to wear a blood pressure cuff on their arm with a small monitoring recording pack (ABPMpro device). The device will take measurements every 2 minutes. Participants will undergo two blood pressure measurements. If the two measurements are not within 5 mmHg for both systolic and diastolic blood pressure, additional measurements will be obtained until this criterion is satisfied. The blood pressure device gives a reliable measurement of the blood pressure, which is an important way to check your heart and blood vessel health This measurement will be conducted on three occasions: before the intervention begins (Visit 1), and after the 4th (Visit 2) and 8th (Visit 3) weeks of the intervention.
