Study aim
-
Effect of strength and endurance exercises on respiratory symptoms, lung function and inflammatory mediators in asthmatic patients.
-
Design
-
Intervention is limited to one group of eligible applicants (30 people) without randomization.
This study does not have a control group.
-
Settings and conduct
-
Exercises will be done for 4 weeks (3 sessions/week). During each session after 10 minutes warming up,endurance training includes treadmills, bicycle and arm ergonomic for 15-20 minutes with Vo2 max = 60% for Elementary sessions, and gradually 60 minutes with Vo2 max = 70-80% for final sessions. Upon completion of endurance training, resistance training include weight lifting. In this exercise, one repetition maximum of the person is calculated first and 50-60% of the 1RM for a set with 15-10 repeats. Gradually, the sets number will reach 3. Static stretching of the entire body and finally cool down for 10 minutes.

Intervention groups
-
After diagnosis of asthma of participants, patients in one group are subjected to intervention with strength and endurance exercises . At the end of the project (30 days), to determine the effect of the intervention, the rate Changes in lung function and asthma attacks , clinical signs, changes in asthma attacks, total and types of WBCs and inflammatory factors will be measured
