Is Performance of a Modified Eucapnic Voluntary Hyperpnea Test in High Ventilation Athletes Reproducible?
PURPOSE Exercise-induced bronchoconstriction (EIB) is common in "high ventilation" athletes, and the Eucapnic Voluntary Hyperpnea (EVH) airway provocation test is the standard EIB screen. Although the EVH test is widely used, the in-test performance in high ventilation athletes as well as the reproducibility of that performance has not been determined. Reproducibility of pre- and post-test spir...
متن کاملIncreased methacholine sensitivity after eucapnic voluntary hyperpnea
Findings In athletes with AHR, the PC20 (expressed as the mean of double concentrations (DC) ± standard error) was 0.7 ± 1.2 DC lower when MIT followed EVH (p = 0.015), while there was no significant difference in athletes without AHR (-0.4 ± 0.8 DC) nor in control subjects (0.4 ± 0.7 DC). When grouping subjects based on the EVH response, those with a positive response (FEV1 fall ≥ 10%) had a m...
متن کاملAirway Response to Methacholine following Eucapnic Voluntary Hyperpnea in Athletes
AIM To evaluate the changes in airway responsiveness to methacholine inhalation test (MIT) when performed after an eucapnic voluntary hyperpnea challenge (EVH) in athletes. METHODS Two MIT preceded (visit 1) or not (visit 2) by an EVH, were performed in 28 athletes and 24 non-athletes. Twelve athletes and 13 non-athletes had airway hyperresponsiveness (AHR) to methacholine, and 11 athletes an...
متن کاملDiagnosing exercise-induced bronchoconstriction with eucapnic voluntary hyperpnea: is one test enough?
BACKGROUND In athletic individuals, a secure diagnosis of exercise-induced bronchoconstriction (EIB) is dependent on objective testing. Indirect bronchoprovocation testing is often used in this context and eucapnic voluntary hyperpnea (EVH) testing is recommended for this purpose, yet the short-term reproducibility of EVH is yet to be appropriately established. OBJECTIVE The aim of this study...
متن کاملUrinary excretion of lipid mediators in response to repeated eucapnic voluntary hyperpnea in asthmatic subjects.
Exercise-induced bronchoconstriction displays refractoriness manifested as a decreased response to repeated exercise challenge within hours. The refractoriness may be attenuated by inhibition of the biosynthesis of prostaglandins (PG). The aim of the study was to determine which PGs and other lipid mediators are excreted during the refractory period. First, 16 subjects with mild stable asthma p...
