Abstract

A testmethod to prevent overtraining in endurance athletes. Well trained endurance athletes with a decrease in performance and symptoms of overtraining were subjected to a standardized testprotocol. The intensities and the duration of the exercise bouts depended on the training-status of the athletes involved. Two bloodsamples were taken, one in the morning of the testday and the second one 24 hours later. The blood chemical variables yielded information about the physiological response to the exercise bouts i.e. muscular integrity, intermediate metabolism and hormonal system. The changes in blood chemistry by physical exercise are described in seven cases. It is indicated that the testprotocol used may contribute to diagnose physical overstress in athletes at an early stage. Verf.-Referat
