Subjects
Twenty-two healthy men, who ran, cycled, or indicated both
represented their dominant training mode of exercise volunteered
for the study. Subjects were initially screened by completing a modified
medical questionnaire (PAR-Q) to exclude those with known
or suspected pulmonary or cardiovascular disease or disorder. The
study was reviewedandapprovedby the campusCommittee for the
Protection of Human Subjects. Preceding the first testing session,
subjects received a verbal and written explanation of the intent,
content, benefits, and risks of the study before providing informed,
written consent.
