Zusammenfassung:	The purpose of this study was to re-examine the effect of training on plasma ACTH levels during exercise. Ten adult volunteers were split into a control and an experimental group. The experimental group participated in a 12-week training program which resulted in a significant 11% increase in their mean maximal oxygen uptake. The plasma ACTH response to a 150W workload was measured in both groups before and after the training program. The experimental group demonstrated a significant reduction in the delta ACTH response to the workload, while the control group demonstrated an unchanged response over the course of the study. These data suggest that the ACTH response to an absolute, submaximal workload is blunted following training. Such a finding is in agreement with previous studies that have shown that ACTH follows an intensity dependent pattern during exercise. Keywords: Exertion; Cycle ergometry; Adrenocortocotropin.
