The Effect of Biological Age on Professional Work Capacity: Report II. Biological Age and Physical Work Ability

The possibility of a prognostic estimation of the body's functional state based on comparative analysis of biological age measured by physical work ability parameters in truck drivers was considered. The dependence of the time course of work ability of the people examined on the calendar age and duration of their employment as drivers was studied. It was found that the range of adaptive responses of the cardiovascular system (CVS) to submaximal physical load narrowed in professional drivers earlier than in the control group. A risk group exhibiting signs of premature aging was revealed. It consisted of 40- to 49-year-old persons who had worked as drivers for 15–19 years. It was demonstrated that the approaches proposed are promising for estimating individual aging rates based on the parameters of work ability and for development of prophylactic measures aimed at the prevention of premature and/or accelerated aging of workers.
