Tomarevska O.S. Physiological Capabilities Supporting the Overall Working Ability of Older Adults. Kyiv: 2014. - 222 p.

Chebotarev NAMS of Ukraine ", Kyiv, 2014. Anthropometric characteristics and functional parameters of respiration, physical working ability and mental capacity, psychomotor activity, sensory abilities, as well as the ratio of functional aging were researched among the older adults. Retrospective professional activities were analyzed in the surveyed seniors. Results of the research were used to justify, develop, and offer a method of quantifying the residual working ability amount of older adults. A quantitative characteristic of factors affecting the residual working ability were evaluated, including professional activity, family and household factors, health indicators, physical activity, nutrition, and the aging ratio of the individual. Persons over 60 years of age with a higher level of residual working ability in comparison to their other peers had a body mass index over 25 kg/m2. Using this method will enable prognostic evaluation of the working ability of the persons at retirement age, as well as regulate their labor activity, that would contribute to longevity and health preservation of the older people. Key words: residual working ability, older workers, overall working ability, mental capacity, gerontechnology, physiological ability, retired people, body mass index.
