MORAES, Eliane Zenir Corrêa de; TREVISAN, Maria Elaine; BALDISSEROTTO, Sérgio de Vasconcellos and PORTELA, Luiz Osório Cruz. Children and adolescents with mild intermittent or mild persistent asthma: aerobic capacity between attacks. J. bras. pneumol. [online]. 2012, vol.38, n.4, pp.438-444. ISSN 1806-3713. http://dx.doi.org/10.1590/S1806-37132012000400005.
OBJECTIVE: To assess children and adolescents diagnosed with mild intermittent or mild persistent asthma, in terms of their aerobic capacity between attacks. METHODS: We included 33 children and adolescents recently diagnosed with asthma (mild intermittent or mild persistent) and 36 healthy children and adolescents. Those with asthma were evaluated between attacks. All participants underwent clinical evaluation; assessment of baseline physical activity level; pre- and post-bronchodilator spirometry; and a maximal exercise test, including determination of maximal voluntary ventilation, maximal oxygen uptake, respiratory quotient, maximal minute ventilation, ventilatory equivalent, ventilatory reserve, maximal HR, SpO2, and serum lactate. RESULTS: No significant differences were found among the groups (intermittent asthma, persistent asthma, and control) regarding anthropometric or spirometric variables. There were no significant differences among the groups regarding the variables studied during the maximal exercise test. CONCLUSIONS: A diagnosis of mild intermittent/persistent asthma has no effect on the aerobic capacity of children and adolescents between asthma attacks.
