Capacidade aeróbica em crianças e adolescentes com asma intermitente e persistente leve no período intercrises

Abstract

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, SpO 2 , 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.Keywords: Asthma; Exercise; Respiratory function tests. ResumoObjetivo: Aferir a capacidade aeróbica de crianças e adolescentes com diagnóstico de asma brônquica intermitente leve ou persistente leve no período intercrises. Métodos: Foram estudadas 33 crianças e adolescentes com diagnóstico clínico recente de asma leve intermitente e asma leve persistente, no período intercrises, e 36 crianças e adolescentes saudáveis. Foram realizadas avaliação clínica, avaliação do nível basal do nível de atividade física, espirometria antes e após o uso de broncodilatador e determinação de ventilação voluntária máxima, consumo máximo de oxigênio, quociente respiratório, ventilação minuto máxima, equivalente ventilatório, reserva ventilatória, FC máxima, SpO 2 e lactato. Resultados: Não foram encontradas diferenças significativas entre os grupos asma intermitente, asma persistente e controle em relação às variáveis antropométricas e espirométricas. Não houve diferenças significativas em relação às variáveis analisadas durante o teste de esforço máximo entre os grupos. Conclusões: O diagnóstico de asma intermitente ou persistente leve não influenciou a capacidade aeróbica em crianças e adolescentes no período intercrises.

Effects of a pulmonary rehabilitation program on physical capacity, peripheral muscle function and inflammatory markers in asthmatic children and adolescents: study protocol for a randomized controlled trial

“…The dyspnea sensation during exercise in these patients is secondary to increases in airway resistance, pulmonary hyperinflation, and hypoxemia observed in severely affected patients [ 2 ]. Some studies have described a reduction in exercise capacity in asthmatic pediatric patients [ 5 – 9 ]. The main hypothesis is that this is due to the deconditioning of the patient, which is a result of the pathogenesis of asthma.…”

“…Cardiopulmonary exercise testing (CPET) is the gold standard for determining exercise intolerance [ 3 , 4 ]. As it is a high-cost assessment, few studies have used CPET as a method to evaluate asthmatic children and adolescents [ 5 – 9 ]. Villa and colleagues [ 6 ] described the reduction of oxygen uptake (VO 2peak ) in patients with moderate/severe asthma when compared to the control group.…”

Physical Activity Level in Asthmatic Adolescents: Cross-Sectional Population-Based Study

“…In addition, they have shown that clinical treatment associated with physical activity improves self-management and symptomatology skills. However, some studies continue to show that asthmatic children practice less PA than their peers, 6 , 7 , 8 although it is not a consensus. 3 , 4 , 9 These data point to a possible behavioral differentiation between asthmatics and the general population regarding physical activity.…”

“…Several studies have shown that asthmatic children practice less PA than their peers. 4 , 6 , 7 , 8 , 13 In this sense, this research aimed to evaluate the level of physical activity in asthmatic adolescents, in comparison with non-asthmatic patients, in a population study.…”

Análise do comportamento cardiorrespiratório em indivíduos com doença pulmonar obstrutiva diante do treino aeróbico por meio da caminhada nórdica

“…A reabilitação pulmonar com ênfase no treinamento físico tem mostrado eficácia na tolerância ao esforço, aumentando a capacidade de realização das atividades de vida diária, tendo em vista que o exercício é recomendado para todo indivíduo com doença pulmonar obstrutiva 6,7 . A capacidade física é o modo como as reações fisiológicas que ocorrem no indivíduo se expressam, logo, a reabilitação pulmonar busca melhorar esta capacidade por meio de exercícios aeróbicos 8,9 .…”
