Home-Based Resistance Training Program in Fontan Patients: it’s Feasible, Safe, and Efficient

BackgroundThe Fontan physiology is characterized by a single functional systemic ventricle that reduces cardiac output adaptation and exercise capacity. Peripheral muscle pump crucial for venous return, resistance training of the peripheral muscles may be particularly beneficial function in these patients. This study explores feasibility program including safety effectiveness, maximal capacity, cardiorespiratory endurance, quality life population.MethodsTwelve patients (18-32 years old) with New-York Heart Association (NYHA) class 1-2 were recruited. The intervention was twelve weeks home-based three sessions per week supervised online physiotherapist. Pre- post- evaluations assessed lean body mass, segmental forces hand-held dynamometer, oxygen consumption (VO2max), cardiovascular leg endurance 1-minute-sit-to-stand test, 36-item Short-Form-Survey.Results11/12 participants completed 35/36 workouts, exceeding our 80% threshold completion. No adverse events reported. Leg strength increased significantly (knee extensors improved 22.8 ± Nm (17.7 %) (p=0.019)). Despite no change VO2max, time showed significant improvement 5.3 minutes (72%). Perceived physical condition evaluated self-perception scale significantly. There difference mass life.ConclusionIn this small group post-Fontan mild impairments, we describe structured, accessible, feasible seems safe improvements perceived condition.
