Children and adolescents with type 1 diabetes (T1D) are at risk of a sedentary lifestyle, as this chronic disease may lead patients into a vicious cycle of deconditioning, resulting in reduced physical activity levels and increased cardiovascular risk.

Our previous studies have demonstrated impaired exercise capacity and reduced quality of life, associated with physical deconditioning and increased sedentary behavior in children and adolescents with other chronic diseases.

This study aims to evaluate cardiopulmonary fitness, physical activity and health-related quality of life in children with type 1 diabetes aged 6 - 17 years and to compare these outcomes with healthy peers. We also aim to evaluate the parameters associated with cardiopulmonary fitness in this population.
