Abstract

During a preparative phase of training 17 oarsmen and -women were subjected to an incremental bicycle exercise test (BE) and to a standardized two-step-test on the Gjessing rowing ergometer (RE). The study investigates the dissimilarities in the behaviour of lactate (whole blood) and of the catecholamines (blood plasma) in relation to the different intensities and procedures of physical stress applied. Results: The maximum values for lactate and catecholamines were higher in RE than in BE. The ratio catecholamines/lactate was higher in maximum RE than in maximum BE. In rowing the ratio catecholamines/lactate was higher in maximum exercise as compared to submaximal exercise. The significance of these findings for the rowing-specific performance diagnosis is being discussed with special reference to the catecholamines. Verf.-Referat
