Abstract
Sex Differences in Ventilation amongst Athletes Undergoing EVH Challenge Testing for Exercise-Induced Bronchoconstriction
Highlights
Eucapnic voluntary hyperpnea (EVH) challenge is an standardised airway challenge which exhibits high sensitivity for detecting Exercise-Induced Bronchoconstriction (EIB) in the elite athlete population [1,2]
The EVH challenge is designed to promote breathing at high ventilation, allowing it to act as a surrogate to exercise
There were no differences noted in anthropometry or baseline forced expiratory volume in 1 second (FEV1) and FVC between EIB positive (n = 12) and negative (n = 65) athletes
Summary
Eucapnic voluntary hyperpnea (EVH) challenge is an standardised airway challenge which exhibits high sensitivity for detecting Exercise-Induced Bronchoconstriction (EIB) in the elite athlete population [1,2]. Few studies have focused explicitly on game players who typically train in an outdoor environment and exhibit high levels of ventilation during training and play [5,6]. Game players such as field hockey or footballers perform high level exercise and require high levels of ventilation, albeit in a sporadic or non-constant manner [7]. Data from elite female field hockey players highlight total distances covered during game play exceed 5 km, and heart rates reach 96% of maximal heart rate (HRmax) [8]
