Exercise Therapy for Asthma (ETA Trial)
The purpose of the study is to determine if a program of regular exercise can help reduce asthma symptoms and also reduce the inflammation caused by asthma. If successful, this would allow regular exercise to be recommended as a therapy for people with asthma, which could possibly reduce the amount of medicine that people with asthma need to control their asthma symptoms.

no exercise program group
group will continue with current level of activity and will be asked not to start an exercise program. They will be seen in the clinic three times a week for 12 weeks. These visits will be very brief; blood pressure, heart rate, oxygen level and peak flow will be measured at each visit
will meet three times a week for 12 weeks, following specific exercise program
This is a randomized, controlled, parallel-design study of the effectiveness of exercise therapy as add-on therapy in the treatment of mild to moderately severe asthma.
105 men and women between the ages of 18-50 years with asthma will be randomly assigned to one of two treatment groups: exercise therapy or control. The exercise therapy protocol is detailed below. The control group will receive usual asthma care. The control group will be instructed to maintain their current sedentary activity level, i.e. not to begin a formal or informal exercise program. In order to standardize contact with study personnel between the two groups the control group will be seen three times a week for clinic visits (exercise group will have sessions three times a week). The primary outcome measures are asthma control (asthma symptom score) and asthma-related inflammation. Secondary outcomes include exacerbation rate, asthma-related quality of life, generic quality of life, lung function, airways hyper-reactivity, and cardiovascular fitness. The effect of exercise therapy on inflammatory markers in blood, and sputum will be assessed by comparing results obtained at study completion versus those obtained at baseline.
