The Effects of Different Run Training Programs on Plasma Responses of Beta-Endorphin, Adrenocorticotropin and Cortisol to Maximal Treadmill Exercise
Abstract
The purpose of this study was to examine the effects of three different run training programs on plasma responses of Beta-endorphin (beta-EP) adrenocorticotropin (ACTH) and cortisol to maximal treadmill exercise. Significant exercise-induced increases in plasma Beta-EP, ACTH, cortisol and blood lactate were observed for both pre- and post-training tests. The SI group demonstrated significant post-training increases in Beta-EP, ACTH, cortisol and peak 5 min post-exercise blood lactate concentrations in response to maximal exercise. No training-induced hormonal changes were observed for the E group. The C group exhibited significant post-training decreases in plasma Beta-EP, ACTH and blood lactate concentrations in response to maximal exercise, while resting and post-exercise plasma cortisol measures were significantly increased in the post-training test. These data suggest that different run training programs produce differential effects on plasma Beta-EP, ACTH and cortisol in response to maximal exercise, and these responses may be linked to anaerobic metabolic factors. Keywords: Endogenous, Opioid peptides, Anaerobic metabolism, Maximal oxygen consumption, Proopiomelanocortin blood lactate.
