[The premature ageing indices among professional drivers]

The studies of biological age, ageing rate, mental and physical work capacity in professional drivers were conducted. The examination revealed peculiarities of system organization of functions, which determine the mental and physical work capacity levels. Dynamics of the ageing process of professional driver's organism in relation with calendar age and driving experience were shown using the biological age model. The results point at the premature decrease of the mental work capacity in professional drivers. There was revealed premature contraction of the range of cardio-vascular system adaptive reactions on submaximum physical load in the drivers as compared with control group. It was proved, that premature age-related changes of physiologic and psychophysiologic indices in drivers are just "risk indicators", while long driving experience is a real risk factor, accelerating the ageing process. The "risk group" with manifestations of accelerating ageing was observed in 40-49-year old drivers with 15-19 years of professional experience. There was demonstrated the expediency of using the following methods for the age rate estimation according to biologic age indices and necessity of prophylactic measures for premature and accelerated ageing prevention among working population.
