Not Applicable
Active, not recruiting
Conditions
High Risk for Developing Breast Cancer
Interventions
Behavioral: Nonlinear Aerobic Training
Other: Height, Weight, BMI measure
Other: Blood draw
Other: Cardiopulmonary exercise test
Registration Number
NCT02494869
Lead Sponsor
Memorial Sloan Kettering Cancer Center
Brief Summary

This study is being done to look at the effect that different amounts of progressive exercise training has on risk factors associated with developing breast cancer. These risk factors include exercise capacity, body weight, and body composition, as well as the expression of certain genes and levels of inflammatory factors in your breast tissue.

The participant will be instructed to self-report the session information to ExOnc staff at or before their next scheduled visit. If the participant's next scheduled visit is greater than 72 hours following an unsupervised session, ExOnc staff may reach out to the participant to retrieve the session information. Unsupervised session details will be source documented by ExOnc staff.

Vital sign monitoring guidelines for unsupervised sessions, prescribed at lower intensities, will be advised by the exercise physiologist at the time the session plan is provided to the patient. Patients will be instructed to not begin an unsupervised session if their resting heart rate or blood pressure is outside the recommended guidelines.

General Physical ActivityBlood drawUsual care patients will receive a home-based, general physical activity program. Specifically, all patients assigned to general physical activity will receive an initial, in-person consultation with staff exercise physiologist outlining a structured home-based aerobic walking program with a goal up to 150 minutes per week outside of their normal daily activity. Patients can be provided with a fitness tracker (e.g. FitBit) to evaluate exercise duration and intensity. Patients may also be provided with an exercise log to records type, duration, and average heart rate during sessions. The exercise log is provided as a guidance tool and may be, although is not required to be, returned to study staff. Staff exercise physiologists will contact patients to check progress and answer questions.
