   Функциональный возраст и работоспособность человека в зависимости от вида труда и образа жизни / А.А. Поляков, Е.С. Томаревская // Журнал Казахстанско-Российского медицинского университета: Актуальные проблемы теоретической и клинической медицины. -  2013. - № 3 – 4. – С. 21 – 22.

SUMMARY
This investigation is dedicated to clarifying of physiological
mechanisms of labor activity in subjects of a different gender
and age with the purpose of a theoretical background of
rational usage of human professional working capacity and
rehabilitation of his health.
Muscle strength and endurance in the women have
expressed age dynamics. The muscle strength of the women
is significantly slashed at 30-35 of years, and the muscle
endurance remains stable up to 55-year’s age. For
the men the dynamics of the muscle strength and endurance
have no obvious age trend, and mostly depend from lifestyle,
physical and labor activity.
It has been showed, that the individually - typological
method at a data analysis allows to receive the new
information in matching with the age approach. It was
found that the calendar age is not the dominating factor in
individual differences of the people on physical work capacity.
In functionally young subjects the working physical work
capacity is 15-20 % higher, compared to an average level,
observed when the functional and calendar ages coincide.
The age related decline the physical working capacity in the
older workers is decelerated owing to the selection of those
who are functionally young and the elimination of those who
age prematurely.
