The acute response to high intensity interval exercise in adults with exercise induced bronchoconstriction

INTRODUCTION: Exercise induced bronchoconstriction (EIBC) occurs as a result of airway cooling and drying in adults with airway hyperresponsiveness (AHR). Continuous exercise leads to a significant decline in lung function; however, interval exercise may allow ventilation to recover and prevent EIBC. PURPOSE: To determine the acute response of lung function and the subjective perceptions during and after a bout of high intensity interval (HIIE), moderate intensity interval (MIIE), and moderate intensity continuous (MICE) exercise in adults with AHR. METHODS: Participants completed an acute bout of HIIE, MIIE, and MICE. Lung function was assessed pre and post-exercise while late phase symptoms were reported using a log and subjective responses were assessed during each minute of exercise. RESULTS: Thirteen participants with EIBC completed all protocols. Lung function was significantly lower following the MICE and perceptions of effort and dyspnea were higher. CONCLUSION: It appears HIIE is well tolerated among adults with AHR.
