Physical fitness and quality of life in adolescents with asthma and fixed airflow obstruction.

Unlabelled: Asthma is a disease characterized by reversible bronchoconstriction, but some subjects develop fixed airflow obstruction (FAO). Subjects with FAO present more asthma symptoms and may have increased sedentary behavior; however, the effect of FAO on aerobic fitness and physical activity levels (PAL) remains poorly understood.

Aim: To compare adolescents with asthma and FAO and adolescents with asthma without FAO in terms of aerobic fitness, PAL, muscle strength, and health-related quality of life (HRQoL).

Barriers to daily life physical activities for Brazilian children with asthma: a cross-sectional study.

Background To identify barriers to daily life physical activities (DLPA) and to evaluate physical activity levels for children with asthma and without asthma. This is a cross-sectional study that enrolled 130 children with asthma and 54 non-asthma, from 7 to 12 years old. All of the children in both groups used an accelerometer for 6 consecutive days to assess DLPA and completed a questionnaire to evaluate barriers to physical activity.

Phenotypes of asthma in low-income children and adolescents: cluster analysis.

Objective: Studies characterizing asthma phenotypes have predominantly included adults or have involved children and adolescents in developed countries. Therefore, their applicability in other populations, such as those of developing countries, remains indeterminate. Our objective was to determine how low-income children and adolescents with asthma in Brazil are distributed across a cluster analysis.

Daily physical activity in asthmatic children with distinct severities.

Objective: The objective of this study was to evaluate daily physical activity (DPA) in asthmatic children with different levels of disease severity, but with good asthma control, relative to a control group.

Methods: This was a cross-sectional study in which a total of 121 children between the ages of 7 and 12 years old were evaluated; 72 were asthmatic children (32 mild, 24 moderate and 23 severe), and 42 children were not asthmatics. The asthmatic children studied had been in medical treatment for at least 6 months and experienced no change in symptoms during the 4 weeks prior to the study.

Exercise training on disease control and quality of life in asthmatic children.

Purpose: Aerobic training has been shown to be effective in improving cardiopulmonary fitness in asthmatic children. However, the actual impact of physical training on clinical indicators of disease control remains controversial.

Methods: Thirty-eight children with moderate to severe persistent asthma were randomly assigned to control (N=17) and training (N=21) groups.
