Diagnostic performance of the physical activity-related question of the GINA questionnaire to detect exercise-induced bronchoconstriction in asthma.

Introduction: The aim of the study was to evaluate the diagnostic performance of the item concerning physical activity of the Global Initiative for Asthma (GINA) asthma control questionnaire for detection of exercise-induced bronchoconstriction (EIB) in children and adolescents.

Material And Methods: We divided participants (aged 6-18 years) with a diagnosis of asthma into two groups according to the GINA severity classification: mild/moderate asthma (MMA) and severe therapy-resistant asthma (STRA). We collected anthropometric, clinical and functional data (spirometry) and performed an EIB test.

Continuous positive airway pressure acutely increases exercise duration in children with severe therapy-resistant asthma: a randomized crossover trial.

Background: Lower exercise tolerance is an important component of asthma and the possible effects of non-invasive ventilation on exercise capacity in individuals with severe therapy-resistant asthma (STRA) are unknown. This study aimed to evaluate the immediate effect of continuous positive airway pressure (CPAP) on exercise tolerance in children with STRA.

Methods: We performed a controlled, randomized, crossover clinical trial including subjects aged 6 to 18 years old diagnosed with STRA.

Determinants of exercise capacity in children and adolescents with severe therapy-resistant asthma.

Objective: To evaluate the exercise capacity of children and adolescents with severe therapy resistant asthma (STRA) aiming to identify its main determinants.

Methods: Cross-sectional study including individuals aged 6-18 years with a diagnosis of STRA. Clinical (age and gender), anthropometric (weight, height and body mass index) and disease control data were collected.

Modified Shuttle Test Distance Correlates With Peak Oxygen Uptake in Children and Adolescents With Severe Therapy-Resistant Asthma.

Introduction: Several tests may be used to assess exercise intolerance in severe therapy-resistant asthma (STRA), including the gold standard cardiopulmonary exercise test (CPET) and the modified shuttle test (MST).

Objective: To correlate the distance achieved in the MST with peak oxygen uptake (VOpeak) and to compare the maximal heart rate (HRmax) obtained in both tests in children and adolescents with STRA.

Methods: This is a cross-sectional study, with 19 children and adolescents with STRA.

Physical exercise recommendations improve postural changes found in children and adolescents with cystic fibrosis: a randomized controlled trial.

Objective: To evaluate postural changes and the distribution of plantar pressures in patients with cystic fibrosis (CF). We also sought to evaluate the effects of an educational guideline for physical activity on body posture in children and adolescents with CF.

Study Design: This was a 2-phase study of individuals between age 7 and 20 years.

Effects of an educational intervention of physical activity for children and adolescents with cystic fibrosis: a randomized controlled trial.

Background: Regular aerobic exercise in patients with cystic fibrosis (CF) improves aerobic conditioning and delays disease progression, resulting in better quality of life. The purpose of this study was to evaluate the effect of an aerobic exercise program based on verbal and written guidelines on maximum exercise capacity using a cardiopulmonary exercise test, quality of life, and the self-reported aerobic exercise practice of children and adolescents with CF.

Methods: This randomized controlled trial followed guidelines for physical exercise in a CF center.
