The Effects of Climate Therapy on Cardiorespiratory Fitness and Exercise-Induced Bronchoconstriction in Children with Asthma

We investigated whether a 1-week stay in the mountains may have positive impact on Exercise-Induced Bronchoconstriction (EIB) and cardiorespiratory endurance asthmatic children from an urban area. Spirometry was performed before 10 min after 20 m shuttle run test (20mSRT) first seventh day of summer asthma camp Italian Alps at 900 altitude. z-scores were derived Global Lung Initiative 2012 prediction equations, percentiles 20mSRT performance assigned according to De Miguel-Etayo’s Tomkinson’s predictive equations. A FEV1 decrease ≥10% exercise defined as EIB. Particulate matter pollution monitored during area provenience. Twenty-four subjects (age range 7–16 years) included. Frequency EIB decreased 58% (14/24) day-1 33% (8/24) end (p = 0.08). Most with lowest quartile 1 had (9/11). The proportion <25° percentile 45% (11/24) 16% (4/24) day-7 0.02). Conclusion: One-week climate therapy improved both bronchial hyperreactivity our cohort children.
