Mechanisms of Dysfunction and the Influence of Exercise on Cardiac and Musculoskeletal Function
Mechanisms of Dysfunction and the Influence of Exercise on Cardiac and Musculoskeletal Function in Children After the Fontan Procedure
Primary Objective: To determine if impairments in cardiac and musculoskeletal function and metabolism exist in Fontan children.
Secondary Objectives:
- To determine if impairments do exist, are they related to exercise capacity.
- To determine if a 12-week exercise training intervention improves cardiac and/or musculoskeletal metabolism.
Hypothesis: The investigators hypothesize that abnormalities in cardiac and skeletal function are evident, influence exercise capacity, and can be improved with exercise training.

Eksperimentel: Fontan Patients
Fontan patients who are monitored at the Hospital for Sick Children (SickKids) will undergo an exercise program
|
The Fontan cohort will subsequently complete a 12-week moderate intensity exercise intervention whereby individualized activity-based home interventions will be prescribed (i.e., sample activities: walking, jogging, swimming, cycling, soccer).
More specifically, individualized weekly exercise programs for participants will be provided incorporating two specific exercise components.

Cardiac and skeletal function and metabolism
Tidsramme: 1 day
|
Blood oxygen level dependent functional magnetic resonance imaging (BOLD fMRI), and 31P-MRS will allow for the precise measurement of cardiac and musculoskeletal function, circulatory perfusion and vascular reactivity, and aerobic and anaerobic metabolism, respectively.
Cardiac function will be examined via MRI and exercise echocardiography.
