Maximal power production is of primary importance for many sporting events. Therefore, using a test that has been shown to be both valid and reliable will allow for accurate baseline testing, measurement of progress, and evaluation of performance. This study examined peak power (PP) during repeated Wingate trials after no warm-up (NWU), a steady state(More)
STUDY OBJECTIVE The efficacy of using impulse oscillometry (IOS) as an indirect measure of airflow obstruction compared to spirometry after exercise challenges in the evaluation of exercise-induced bronchoconstriction (EIB) has not been fully appreciated. The objective was to compare airway responses following room temperature and cold temperature exercise(More)
BACKGROUND The efficacy of impulse oscillometry (IOS) to measure airway calibre change is not fully established. OBJECTIVES To evaluate lung function change after eucapnic voluntary hyperventilation (EVH), and to compare IOS indices with spirometric maximal expiratory flow measurements. METHODS Twenty subjects (10 airway hyperresponsive [AHR+] and 10(More)
PURPOSE Exercise-induced bronchoconstriction (EIB) is high among ice rink athletes and may be related to exercise ventilation of rink air pollutants. Impaired postchallenge expiratory flows are common for this population; however, baseline lung function and symptoms have not been fully evaluated. METHODS We examined resting lung function and asthma-like(More)
Airborne ultrafine and fine particulate matter (PM1 from fossil-fueled internal combustion engines may cause abnormal airway narrowing. Because of high PM1 exposure from ice resurfacing machines, the ice-rink athlete is especially vulnerable to PM1 toxicity. The purpose of this study was to evaluate protection by a single dose of montelukast in college ice(More)
INTRODUCTION Exercise-induced bronchoconstriction (EIB) is thought to result from osmotic and thermal events of air conditioning during exercise at high ventilation rates. The purpose of this study was to evaluate lung function after exercise and eucapnic voluntary hyperventilation (EVH) while breathing both room-temperature and cold-temperature dry bottled(More)
PURPOSE Reactive oxygen/nitrogen species (ROS/RNS) in resident airway cells may be important in bronchoconstriction following exercise. Glutathione (GSH) is a major lung antioxidant and could influence pathological outcomes in individuals with exercise-induced bronchoconstriction (EIB). This study examined the effects of supplementation with undenatured(More)
Airway responses were compared following 6-minute eucapnic voluntary hyperventilation and 6-minute exercise challenges by examining resting and post-challenge impulse oscillometry and spirometry variables. Twenty-two physically active individuals with probable exercise-induced bronchoconstriction took part in this study. Impulse oscillometry and spirometry(More)
PURPOSE To examine the effects of a single 10-mg dose of ML on physical performance in EIB- and EIB+ athletes. METHODS Twenty-four male college ice hockey players performed two 6-min maximal work accumulation bouts on an electronically braked cycle ergometer in subfreezing conditions (-2.5 +/- 0.4 degrees C) 6-8 h after either ML or placebo (PL) to obtain(More)
