Motor car racing can be considered as a model of extreme, primarily psycho-emotional-concentrative stress, which is increasing more and more under modern situations of life. In the present paper, the physiological response of heart rate and catecholamine excretion in urine was investigated as were various parameters of carbohydrate and lipid metabolism (lactate, glucose, free fatty acids, total protein, insulin, human growth hormone) in drivers during car races (formula Ford and Renault-5-Cup) and during exhausting physical exercise, performed within about one week of the races, on a bicycle ergometer in the laboratory. Furthermore, the lipid metabolism status and glucose tolerance were examinated.
The results of this investigation show that the cardiocirculatory and metabolic reaction to psychoemotional stress decreases with increasing physical performance capacity/endurance training state. Finally, significant relationships between training state on the one hand and HDL-cholesterol as well as glucose tolerance on the other hand were found.
