Abstract des Autors
An exercise intensity-related response of beta-endorphin beyond the anaerobic lactate level of 4 mmol/l has been postulated. We therefore examined the changes in the plasma levels of beta-endorphin (B-E) and catecholamines along with the lactate concentration (LCT) at three different loads concerning specific kinds of sport (riding, number of subjects n=11; handball, n=10; diving, n=14) and after an exhaustive treadmill-ergometric load (n=10 track and field athletes). Diving was followed by a significant increase of LCT below the anaerobic threshold but was associated with a highly significant increase (+343%) of B-E. By contrast, handball, which leads to a significant increase of LCT, was associated with only a minor change (+52%) of B-E and riding did not change B-E levels at all. We conclude that the strong correlation between B-E and LCT changes during exhaustive treadmill-ergometry is not observed when athletes are subjected to different loads concerning specific kinds of sport.
