[Determination of biological age--a group of biophysical tests].

BACKGROUND
Biological age is defined as real state of organism with respect to the processes of aging. From the gerontological point of view, the methodology of determination of biological age is a tool for verification of theories. The role of biological age determination in medicine is wide. It consists, among others in the assessment of the efficiency of anti-aging interventions or in detection of premature aging. Many different batteries of methods for the measurement of biological age were developed till now. The currently applied methods are not standardized and they are, as a rule, significantly time-consuming.


METHODS AND RESULTS
The goal of the work was to develop a routine method for biological age determination. Simplicity and reproducibility of measurements was stressed. The result of our work is a set of 7 biophysical methods. Some of the methods are newly developed (measurement of rheological properties of the skin), others are modified classical methods (measurement of accommodation of eye, perception of high frequencies of sound, reaction times).


CONCLUSIONS
The battery of biophysical test for the routine biological age assessment was developed in our laboratory. The information is processed by computer, using multiple linear regression analysis for obtaining the best assessment of personal biological age. The duration of measurement is roughly 120 min.
