简要总结
The investigators will explore the feasibility and safety of two exercise interventions delivered both in the hospital and in participants' homes. Preteens and adolescents who have had repaired Tetralogy of Fallot (TOF), will be grouped by age and randomly assigned to either an aerobic or strength training exercise program supervised for 12 weeks. An exploratory aim of this study will be to examine changes in fitness level, muscle strength, muscle oxygen extraction and quality of life after the intervention, and compare these measures between groups. At the end of the study, participants and parents will be interviewed to assess their satisfaction and ideas for improvements in the program.
详细描述
While adult cardiac rehabilitation (CR) is an established clinical practice, the conceptualization, design and utility of pediatric CR programs have been poorly studied. Particular challenges for children with heart disease include uncertainties regarding physical activity restrictions imposed by clinicians and overprotection by caregivers. These challenges may lead to poor lifestyle and deconditioning, resulting in increased health risks associated with inactivity, such as adiposity, and reduced perceived general health and quality of life. Preliminary studies have shown therapeutic benefits of physical exercise as an add-on therapy in an effort to improve patients' functional outcome after cardiac surgery 1; however, delivery of these programs has been variable, and it is not clear whether a combined program of facility and home-based exercise would yield higher patient adherence for children. The investigators hypothesize that a supervised exercise training program delivered both in the hospital and in participants' homes will be acceptable and feasible for children with repaired Tetralogy of Fallot (TOF). The investigators will conduct a pilot trial over 1 year in which the investigators will randomize 20 participants to either aerobic exercise only or a combined aerobic and strength training program for 12 weeks. The investigators will conduct qualitative interviews to understand intervention acceptability. Results will support a larger definitive study aimed at determining efficacy.

结局指标
主要结局
Consent rate
时间窗: 1 year
The proportion of participants consented to participate in the study
Adherence rate
时间窗: 1 year
The proportion of participants who adhered to the study intervention based on the number of completed training sessions divided by the total number of training sessions available
Completion rate
时间窗: 1 year
The proportion of participants who completed the study intervention
Enrolment rate
时间窗: 1 year
The proportion of participants who consented and eligible to participate in the study
Attrition rate
时间窗: 1 year
The proportion of participants who withdrew or lost to follow up
Acceptability questionnaire (Investigator-generated satisfaction questionnaire)
时间窗: 1 year
The proportion of participants who were satisfied with the study intervention. An investigator-generated satisfaction questionnaire was created to assess the many components of acceptability of the exercise intervention program. Participants will be provided with statements related to the study intervention, for example "the exercises were enjoyable", and participant will rate these statements based on whether they Strongly Agree, Agree, Neither Agree nor Disagree, Disagree, and Strongly Disagree
