The relationship between asthma and exercise can be challenging to navigate for patients as exercise is a common trigger of asthma symptoms such as shortness of breath, cough and wheeze. However, more and more evidence suggests exercise has a tremendously beneficial impact on asthma and overall health.
A group in Denmark evaluated 150 adults with persistent asthma requiring treatment with a daily corticosteroid inhaler. They had 1 group perform HIIT (defined as 3 sessions of 30 minutes per week with heart rate above 90 % maximum for at least 16 minutes) and the other group continued their standard therapy – including any form of exercise they would typically perform.
After 6 months, the HIIT group were able to reduce their inhaled corticosteroid dose by an average of 24 %. The control group had no significant decrease.
Asthma symptoms and qualify of life also improved significantly in the HIIT group as compared to the control group.
Overall, this study adds to the growing body of evidence that exercise can be a useful tool in the treatment of asthma. It can reduce prescription medication use, alleviate symptoms and improve quality of life.
