title: [Peculiarities of the functional parameters of performance in late ontogenesis].
abstract: The age parameters of physiological characteristic values of the capability of 647 persons doing non-mechanised work in agriculture and of 799 practically healthy machine operators and female machine sewers were determined. Data on the adaptabilities of physiological functions were obtained that are responsible for the activity at physical work. The functional importance of changes of the organism in ontogenesis for maintaining the occupational capability is reviewed. It was found that the nervous system and the muscular system as well as the cardiovascular system restrict the job opportunities of age workers. With self-determined pace and rhythm of work the nervous and muscular system of aged people shows long-term capability.
