Official title
Digital Intervention to Promote Physical Activity and Improve Cardiovascular Health Among Cancer Survivors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a behavioral study that will examine changes in physical activity and vascular health in response to a digital tool (app) that will appear on participant's lock screen of their Android phone. Participants will be asked to use this app for 3 months and to wear a Fitbit device continuously throughout the study. Participants will be asked to complete questionnaires, participate in fitness testing and measures of cardiovascular health at 3 months and 6 months after baseline assessments. The hypothesis is that exposure to the app will lead to increased physical activity volume and improved microvessel function.
