Abstract
We determined the release of beta-endorphin and prolactin into the blood, before and after 60-minute exercise of acute cycle ergometer in five healthy students and three athletes. This exercise induced an increase in circulating mean beta-endorphin level (basal to after exercise level, 14.9+/-0.7 pg/ml to 57.1+/-17.0 pg/ml:p<0.05) and mean prolactin level (9.4+/-0.7 ng/ml to 19.1+/-3.1 ng/ml:p< 0.01). There was a significant correlation between beta-endorphin and prolactin values in all samples (r=0.892: p<0.01: n=32). Athletes tended to release greater amounts of beta-endorphin and prolactin into the blood than students after acute exercise. We find that acute exercise stimulates release of betaendorphin and prolactin in parallel and athletes have increased plasma betaendorphin and prolactin after acute exercise. Verf.-Referat
