Abstract
Abstract Objective This systematic review delineates various exercise‐based pulmonary rehabilitation (PR) designs and quantifies how they may be optimized in pediatric asthma treatment. Design Comprehensive systematic review, network meta‐analysis, and quality analyses using PubMed, Embase, Cochrane Library, Web of Science Core Collection, and Medline searches. Interventions Discrete and combined endurance, respiratory, resistance, strength, and interval training. Main Outcome Measures Forced expiratory volume at 1 s to predicted value ratio (FEV 1 % pred), forced vital capacity to predicted value ratio (FVC% pred), forced expiratory flow between 25% and 75% of vital capacity ratio (FEF25%–75%), the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and the 6‐min walk test (6MWT). Results Twenty‐four randomized controlled trials (RCTs) involving a combined 1031 patients were included. Endurance training was the most common form of PR (58.3%), typically conducted through outpatient clinics (29.2%). Network meta‐analysis showed that compared with other PR, interval training significantly improved PAQLQ total scores, and activity, symptom, and emotional domains. Interval training also had a significant effect on the 6MWT. No adverse events were reported. Exercise training did not have a significant effect on FEV 1 % pred; however, combined endurance and respiratory training significantly improved both FVC% pred and FEF25%–75%. Conclusions Exercise‐based PR is safe and effective in childhood asthma treatment. Interval training may be a core component for improving quality of life and exercise capacity in this patient population, while combined respiratory and endurance training may significantly affect lung function. The clinical efficacy of these results should be confirmed through high‐quality RCTs.
