Fontan Fitness Trial
Recruiting now · Not applicable
Conditions studied: Single-ventricle, Congenital Heart Disease
In brief
The goal of this randomized control trial is to learn about physical fitness and exercise habits in children aged 10-17 with the Fontan Circulation through a home-based, digital exercise intervention. The main questions it aims to answer are: * Does a home-based, digital intervention increase physical activity (PA) in youth with the FC compared to enhanced usual care? * Does a home-based, digital intervention increase physical fitness in youth with the FC compared to enhanced usual care? * Do multi-level factors (medical, neurodevelopmental, sociodemographic, neighborhood) impact the effectiveness of the digital intervention? Researchers will compare participants in the enhanced usual care arm to those in the exercise intervention arm to see if the digital intervention is effective. All participants will wear a PA tracker for 12 months and complete testing at baseline, 6 months, and 12 months. In addition, participants in the exercise intervention arm will complete a 6-month exercise intervention with the following components: * aerobic exercise * resistance exercise * engagement strategies
