Item The acute response to high intensity interval exercise in adults with exercise induced bronchoconstriction(2016-05-01) O'Neill, Carley; Dogra, ShilpaINTRODUCTION: 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.Item The acute response to sprint interval exercise and moderate intensity continuous exercise in adults with and without airway hyperresponsiveness(2017-07-01) Good, Joshua; Dogra, ShilpaIntroduction: Sprint interval exercise (SIE) has been proposed as a time efficient way to improve physical activity levels; however, SIE has not been studied in adults with airway hyperresponsiveness (AHR). Methods: Eight adults with AHR and eight adults without AHR completed both SIE (4x30 second sprints at 7.5% body weight) and moderate intensity continuous exercise (MICE) (20 minutes at 65% peak power output). Spirometry, ventilatory measures, tissue oxygenation, and subjective responses were assessed prior to, during, and following exercise. Results: The decline in forced expiratory volume in one second was similar following SIE and MICE. Ventilatory measures, tissue oxygenation, and subjective responses were similar in the AHR group compared to those without AHR. Differences were observed in affect, breathlessness, and exertion between SIE and MICE at the onset of exercise. Conclusions: SIE appears to be feasible in adults with AHR; this may have implications for exercise prescription in this population.
