Abstract des Autors

The analysis of sympathetic activity (catecholamine behaviour) can provide supplementary information for performance diagnostics and training management. In the incremental test on bicycle and treadmill ergometers, the plasma noradrenaline level prior to exercise and at the submaximum absolute exercise level showed negative correlation to the aerobic capacity, while the submaximum laboratory value correlated positively to the duration in the field test of suitable types of sports. In the supramaximum test on the treadmill ergometer ("open-end" test), the catecholamine level correlates negatively to the duration. In competition, the plasma adrenaline concentration prior to the start correlates positively to the competition time (800 m, female athletes). In physical-concentrative stress (ski flying, sailing), more favorable competition results are usually accompanied by lower and more stable catecholamine excretion. Progressive observations of athletes show that a greatly elevated basal, that is nightly catecholamine excretion, may correspond to a complex overexertion situation and a subnormal excretion may correspond to a training-related exhaustion syndrome.
