Progressive bicycle exercise in asthmatic children

ABSTRACT Twenty seven asthmatic children (A) aged 126 ± 29 months, and twenty seven ordinary children of the same age (C) were studied. FeO2, FeCO2, minute ventilation (VE), breathing

frequency (BF), heart rate (HR), blood pressure (BP), oxygen consumption (VO2) and respiratory exchange ratio (QR) were determinated during each stage of the progressive exercise and during

the recovery. In the asthmatic group, there are significant decreases of FeO2, FeCO2, VO2, load and QR at each stage and during the maximal exercise (Table I) The cardiac and respiratory

recovery at 10 min were slower in A than C : BF = 120 ± 11 vs 104 ± 3 (p < 0,01) and DVO2 = 0,10 ± 0,11 vs 0,01 ± 0,15 ml/min (p < 0,05). Ventilation-perfusion maldistribution and

obstruction during the exercise could explain the little limitation at the exercise in this group of asthmatic children. ARTICLE PDF AUTHOR INFORMATION AUTHORS AND AFFILIATIONS * Unité de
