[Assessment of accelerated aging among automobile drivers using model of the biological age based on physical work...

The studies of biological age, aging rate, physical work capacity in professional drivers were conducted. The examination revealed peculiarities of system organization of functions, which determine the physical work capacity levels. Dynamics of the aging process of professional driver's organism in relation with calendar age and driving experience were shown using the biological age on physical work capacity model. The results point at the premature decrease of the physical work capacity in professional drivers. The premature contraction of the range of cardio-vascular system adaptive reactions on submaximum physical load in the drivers as compared with control group was revealed. It was proved that premature age-related changes of physiologic 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. 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 was demonstrated.
