Abstract
ABSTRACT Introduction: Asthma is the most common chronic disease in childhood and its prevalence has increased in recent years. Although regular physical activity (PA) is considered to be beneficial for the health of asthmatics, especially children and adolescents, it can also be one of the elements that triggers asthma. This is known as exercise-induced bronchospasm (EIB), and is considered one of the factors that limits asthmatics’ participation in PA. Objective: This study aims to review the effects of physical conditioning on EIB in asthmatic children and adolescents. Methods: A systematic review was carried out on the Pubmed, Bireme and Web of Science databases, considering publications from 1998 to April 2019. Results: Eight articles were retrieved; five of the articles presented no significant difference in EIB parameters after physical training, and three demonstrated significant benefits in EIB. Conclusion: There is insufficient evidence that physical training helps reduce the frequency and severity of EIB in young asthmatics. There are still few studies that seek to show the effect of a physical training program on the improvement of EIB in children and adolescents. It is suggested that further randomized clinical trials be conducted, to investigate the effects of physical training on EIB parameters in children and adolescents. Level of Evidence II; Systematic review.

Differences observed between the articles were due to: age, physical exercise parameters, evaluation methods and EIB classification criteria
Summary
Asthma is the most common chronic disease in childhood and its prevalence has increased in recent years. Regular physical activity (PA) is considered to be beneficial for the health of asthmatics, especially children and adolescents, it can be one of the elements that triggers asthma. This is known as exercise-induced bronchospasm (EIB), and is considered one of the factors that limits asthmatics’ participation in PA. Bronchial asthma is the most common chronic disease in childhood and adolescence, and its prevalence has increased in recent years.[1,2] This disease is characterized as an airway inflammatory disease that causes airflow limitation and bronchial hyperresponsiveness, leading to wheezing, dry cough and shortness of breath, and which has impact on sleep quality, daily activities and quality of life[3]. The exact mechanism responsible for EIB is still uncertain, but factors such as airway cooling and dryness during physical activity seem to trigger bronchospasm.[10]
