Evidence Summary
Self-reported asthma symptom scoring and number of symptom free days have been examined in a small amount of studies. Improvements in asthma control and experience of asthma related symptoms were all improved within groups undertaking a physical activity intervention.

Quality of Evidence
B – moderate quality
Strength of Recommendation
1C. Strong recommendation, low quality evidence due to limited number of studies.

Conclusion
Daily physical activity has been found to improve self-reported asthma symptoms and asthma control. Due to the limited number of studies using this as an outcome measure it is not possible to recommend one level of exercise intensity over another. Reassuringly no studies reported any worsening of clinical symptoms in groups that exercised.
