effects of a period of selected activity on lung capacities in children 5-10 years with asthma caused by exercise

background: aasthma due to causing disruption in the work of breathing and obstruction of the pulmonary tract creates the physical restrictions in the social, emotional and psychological, aspects and performing daily life activities, hence the present study is conducted to determine the impact of a period of selected activity on some spirometry parameters of children from 5 to 10 years old suffering from asthma caused by exercise.materials and methods: in this half experimental respiratory research, respiratory indexes of 11 children including 5 boys under the age of 10 years old suffering from asthma caused by exercise were measured before and after eight weeks of selected exercises and pranayama by spirometry were measured.results: the results showed that the selected exercise routine improves on the status of activities and being short of breath (z=0/003). also the average of spirometry indexes prior to a ten minutes exercise, before and after the intervention, compared with the average of spirometry indexes after a ten minute exercise, before and after intervention in the parameters: (fev1) the volume of the expiratory force in the first second, and (pef) the maximum expiratory flow, the results are statistically significant (p 0.05).conclusions: the present study shows the impact of the selected exercises in improving mobility status and being short of breath and reducing asthma symptoms caused by exercise (eia) as well as strengthening the respiratory muscles significantly.
