The effects of natural supplements on exercise-induced bronchoconstriction

13 February 2018

This study is being undertaken as part of a postgraduate research project within the School of Science and Technology at Middlesex University. Exercise-induced bronchoconstriction following intensive exercise is common in physically active people, particularly those with asthma. Common symptoms can include wheezing, tightness of chest, and coughing. The purpose of this study is to investigate the effectiveness of natural supplements on markers of pulmonary function and inflammation.
