Article Synopsis
- - The study compares six existing equations used to estimate peak work rate (Wpeak) for COPD patients with actual Wpeak measurements, and it aims to create a new equation based on the six-minute walk distance (6MWD).
- - Results showed that 82% of patients had inaccurate Wpeak estimates from the existing equations, while a newly derived equation was more accurate but still showed discrepancies in 74% of cases.
- - The conclusion indicates that relying only on 6MWD to estimate peak workload in COPD patients is often unreliable, suggesting that cardiopulmonary exercise testing (CPET) should be included for better assessment before rehabilitation.
To establish whether asthma affects physical activity levels in children (aged 7-10 years) we evaluated physical activity levels in children with undiagnosed asthma (UDA), diagnosed asthma (DA), and healthy controls (HCs). A cross-sectional community-based study was performed which included a parental questionnaire on their child's respiratory health, and testing of airway reversibility and bronchial hyperresponsiveness (BHR). DA was defined as the parents' confirmation of a physician's diagnosis of asthma in the past 12 months.

The aim of this study was to develop a modular aerobic training program for adolescents with severe obesity, with a focus on variety, individual targets and acquiring physical skills. We report here the effects on aerobic fitness from a pilot study.

Additionally, these patients have diminished skeletal muscle performance and exercise capacity. We hypothesize that a mixture of multiple micronutrients could have beneficial effects on pulmonary function and muscle performance.

Anaerobic exercise performance in children with cystic fibrosis (CF) has received little attention compared to aerobic performance. This study investigated the effects of anaerobic training in children with CF.
View Article and Find Full Text PDFBackground: Several cross-sectional studies in patients with cystic fibrosis (CF) have shown that nutritional status and lung function are important determinants of peak aerobic capacity (peak oxygen uptake [O(2)peak]). In order to account for individual changes, the aim of this study was to determine the longitudinal relationship of changes in nutritional status, lung function, and O(2)peak in children with CF.
Design And Methods: Fat-free mass (FFM), lung function, and O(2)peak were assessed in 65 children with CF at baseline (mean +/- SD age, 10.
