[The ageing-factors of several physical functions in man (author's transl)].

The ageing-factor is a measure for the rate of ageing. In the model of vitality the error rate mu corresponds to the ageing-factor. The ageing-factors of several physical functions can be determined from the ascent of decrease of these functions. The standardized ageing-factors of the considered physical functions range from 0,001 to 0,017 year-1 and are smaller than the ageing-factor of the whole organism. The date of the occurrence of pathological manifestations as a result of ageing-conditioned decrease of functions can be estimated by means of the ageing-factors.
