exercise induced asthma (eia) is a transient increase in airway resistance after intensive exercise and can be measured as a decline in forced expiratory volume in one second (fev1). the condition is due to increased training load and inhalation of cold and dry air. several studies have shown that eucapnic voluntary hyperpnea challenge test (evh test) is a very sensitive and specific diagnostic...

the prevalence of exercise induced asthma (eia) in iran is not known. in the present study the  prevalence of  eia  among female students  of  guidance school  in the  city of mashhad was evaluated. a total of 1690 female students aged 12-14 years in ten randomly selected schools in north east of iran (mashhad) completed an asthma symptoms- specific questionnaire. one hundred forty four randoml...

asthma is the most prevalent chronic disease in childhood. to determine the prevalence of asthma and related symptoms in children younger than 5 years, a survey was performed by interviewing mothers of 617 children during spring 2001. the interview comprised of two parts. the first part contained children characteristics including age, sex, maternal age at the child birth, child history of atop...

BACKGROUND Exercise induced asthma (EIA) plays an important role in clinical evaluation. There has been little previous work validating EIA as reported directly by children and indirectly by their parents. AIMS (1) To determine the strength of the association between children's symptoms of EIA and their physiological response to exercise in a laboratory setting. (2) To compare parents' percep...

We have tested the effect of a porous cellulose fabric face mask. Nine asthmatic patients, anamnestically sensitive to cold, took part in exercise tests on an ergometer bicycle at a temperature of approximately -10 degrees C, with and without a face mask. For comparison, exercise tests were also performed with breathing taking place through a woolen scarf. Three minutes after finishing the exer...

This review will encompass definition, history, epidemiology, pathogenesis, diagnosis, and management of exercise -induced bronchospasm in the pediatric individual with and without known asthma. Exercise induced asthma is the conventional term for transient airway narrowing in a known asthma in association with strenuous exercise usually lasting 5-10 minutes with a decline in pulmonary function...

The development of airflow limitation that occurs in 70-80% of people with asthma several minutes after vigorous exercise is known as exercise induced asthma. In most asthmatic patients the airflow obstruction is reversed spontaneously within 60 minutes. There are, however, asthmatic individuals who have more prolonged airways obstruction and who require bronchodilator treatment to recover pre-...
