Dysregulation within both respiratory control systems and the hypothalamic-pituitary adrenal (HPA) axis has been implicated in the pathophysiological of panic disorder. However, potential linkages between respiration and the HPA axis have rarely been examined in panic patients. We have previously published neuroendocrine and psychophysiological response data from a laboratory panic model using ...

The purpose of this study was to reexamine the effect of training on plasma adrenocorticotropin (ACTH) levels during exercise. Ten adult volunteers were split into a control and an experimental group. The experimental group participated in a 12-wk training program that resulted in a significant 11% increase in their mean maximal O2 uptake. The plasma ACTH response to a 150-W work rate was measu...
