Abstract des Autors

The aim of the Symposium was to summarise the present state of knowledge on performance diagnostics, to show the deficits and to query the practicability in regard to individual sports. It became clear, however, that in spite of a well tested theoretical basis of the regularly used diagnostics of aerobic performance, problems exist in regard to standardisation and interpretation of measuring results under laboratory conditions. Differentiated diagnostics of the anaerobic preconditions of performance are still at the beginning of a promising development. The results gained under laboratory conditions can at present usually only serve as an orientation in regard to performance to be expected in an individual sport. Sport specific field tests show, in spite of considerable problems concerning standardisation and measuring techniques, training effects better than laboratory tests. In endurance sports they can to some extent enable a prognosis of competition results. It is still not clear, however, whether both field tests and laboratory tests can lead to individual training recommendations which guarantee a maximum increase in performance. In spite of all the empirical progress it is also still open as to which biochemical parameters should be observed in the training process in order to prevent overtraining. The Abstracts of the chiefly substantiated, original and to a great extent critical contributions point out the present limits of the practical use of performance diagnostics. Only some problems are answered. They mainly raise questions which can be used as helpful orientation for further specific scientific research. Verf.-Referat
