Resistance and reactance at 6 and 8\u2009Hz (Rrs6, Rrs8, Xrs6 and Xrs8, respectively) were measured using the forced oscillation technique and specific airway resistance was measured in a plethysmograph. <jats:italic>z<\/jats:italic>\u2010Scores were calculated from published reference data. Tests were repeated 15\u2009min after 400\u2009mcg salbutamol.
