[Determination of biologic aging within the scope of the Halberstadt Gerontologic Study. 4. Some theoretical and methodologic considerations on the future development of assessment tests].

With regard to the test-set developed by RIES and co-workers for the purpose of determination of the biological age the authors again refer to the necessity of a corresponding catalogue of methods with a view to the measurement of work capacity and of health condition at the age. Theoretic problems concerning the examination of functional parameters are discussed. Proposals to a theory-related continued development of work capacity and of health condition are presented, especially to master common problems of daily life at the age.
