Subjects completed a graded exercise test on a Monark cycle ergometer while expired gases were collected to determine maximal oxygen consumption (VO<sub>2max</sub>). Subjects then returned on a second day when measurements of each subject's Pe<sub>max</sub>, were made prior to riding at the workload corresponding to 90% of their VO<sub>2max</sub> until exhaustion. Measurements of expiratory pressure (Pe) were then made immediately post exercise (Pe<sub>IPE</sub>), one minute post exercise (Pe<sub>1MIN</sub>), three minutes post exercise (Pe<sub>3MIN</sub>), and five minutes post exercise (Pe<sub>5MIN</sub>). Trained cyclists had a significantly higher Pe<sub>max</sub> (x = 116.43 ± 7.76 mmHg) than did untrained subjects (x = 65.75 ± 7.09 mmHg). Also trained cyclists generated a higher absolute Pe throughout recovery than did the untrained subjects. Although expiratory pressure decreased after exercise in both groups, the relative change in Pe over the recovery period, expressed as a percentage of Pe<sub>max</sub>, was not different between trained and untrained. Pe<sub>IPE</sub> was decreased to 81.87% ± 3.12 of Pe<sub>max</sub>in trained subjects and 82.35% ± 2.85 in untrained subjects (p < .05), recovering somewhat at 1 minute to 89.19% ± 3.59 of Pema, in trained and to 87.74% ± 3.27 in untrained (p < .05) but did not recover to resting levels in either group. Pe<sub>3MIN</sub> and Pe<sub>5MIN</sub> remained at the same level as Pe<sub>1MIN</sub> in both groups.
