Résumé
The exercise challenge is the gold standard for diagnosing exercise-induced bronchoconstriction (EIB). Airway obstructions appear up to 30 min after the challenge, with a maximum decrease in spirometry and a maximum increase in airway resistance. There is evidence that changes in body plethysmography parameters are more sensitive to the exercise challenge and precede those in spirometry. To compare changes in body plethysmography and spirometry parameters after exercise challenges and to verify the cut-off values of sReff in EIB. In 82 subjects with suspected EIB, a total of 473 lung function tests were measured at baseline and at 5, 10, 15, and 30 min after exercise challenges at different stages of bronchial obstruction. The maximum changes in the body plethysmography parameter sReff significantly preceded the maximum changes in the spirometry parameter FEV The changes in sReff were more sensitive and better indicated lung impairment than did the changes in FEV

BACKGROUND
The exercise challenge is the gold standard for diagnosing exercise-induced bronchoconstriction (EIB). Airway obstructions appear up to 30 min after the challenge, with a maximum decrease in spirometry and a maximum increase in airway resistance. There is evidence that changes in body plethysmography parameters are more sensitive to the exercise challenge and precede those in spirometry.
PURPOSE
To compare changes in body plethysmography and spirometry parameters after exercise challenges and to verify the cut-off values of sReff in EIB.
PROCEDURES
In 82 subjects with suspected EIB, a total of 473 lung function tests were measured at baseline and at 5, 10, 15, and 30 min after exercise challenges at different stages of bronchial obstruction.
FINDINGS
The maximum changes in the body plethysmography parameter sReff significantly preceded the maximum changes in the spirometry parameter FEV
CONCLUSION
The changes in sReff were more sensitive and better indicated lung impairment than did the changes in FEV
