Abstract
Asthma prevalence and severity have increased over the last 4 decades, many explanations for the increase have been postulated but none of them are sufficient to explain the scale or consistency of the change.
It is becoming increasingly evident that the cause of the changes in asthma must be multifactorial, including contribution from allergen exposure, hygiene and lifestyle changes mainly of diet and physical activity and their product (obesity) (Sean et al. , 2005).
A prescription for exercise has been endorsed for all asthmatic children by the American College of Sports Medicine (ACSM) and the American Thoracic Society (ATS), (Orenstein, 2002 & Nystad et al., 2001).
Exercise has long been recognized as a possible method for improving subjective and objective asthma indices (Rasmussen et al., 2000) thus reducing the need for medication, fewer visit to the emergency department, decreased exercise- related fear and anxiety, and less absenteeism from
the school.
