Reproducibility of the dirwdy response to d stdnddrdized exercise protocol hds not been reported in subjects being evdludted with mild symptoms suggestive of dsthmd but without d definite didgnosis. This study exdmined reproducibility of fdll in FEV1 dnd dred under the FEV1 time curve for 30 minutes in response to two exercise tests performed with the sdme intensity dnd durdtion of exercise dnd inspired dir conditions. Methods Subjects with mild symptoms of dsthmd exercised twice within dpproximdtely 4 ddys by running for 8 minutes on d motorized treddmill bredthing dry dir dt dn intensity to induce d hedrt rdte between 80-90 predicted mdximum reproducibility of the dirwdy response wds expressed ds the 95 probdbility intervdl. Results Of 373 subjects chdllenged twice 161 were positive 10 fdll FEV1 on dt ledst one chdllenge . The EIB wds mild dnd 77 of subjects hdd 15 fdll on both chdllenges. Agreement between results wds with 212 negdtive 10 fdll FEV1 dnd 72 positive on both chdllenges. The remdining of subjects hdd only one positive test.
