Associações entre força muscular periférica, força muscular respiratória e desempenho em idosos de um município do interior do Amazonas

Abstract

In view of the new population configurations, which are being traced every day with the quantitative advance of elderly people on a global scale, it is extremely important that what factors are associated and acts as gerontological determinants. However, few studies are intended to explain, what are the variables directly or indirectly related to measures of functional performance. For this reason, elaborate this research, of transversal, descriptive and analytical character, with individuals of the generated population residing in the urban area of Coari, inner city of the northern region of Brazil. As the initial selection method addresses a representative sample, through active searches and home interviews, which includes questions about the sociodemographic profile and health history. The inclusion / exclusion requirements were: age equal to or above 60 years old, signing a Free and Informed Consent Form, score on the Mini-Mental State Examination below or equal to 13 and no altered pathologies are allowed at all, or movement. In a second stage, the selected were sent to laboratories of the Institute of Health and Biotechnology of the Federal University of Amazonas in Coari, to perform as tests: handgrip strength test, maximum one-repetition strength test, manovacuometry and gait speed test. Response variables were adopted as they are related to peripheral muscle strength, respiratory muscle strength and performance. As regressive variables, the participants of personal aspects, behavioral aspects and health status. A final sample of 197 individuals was composed of all those who managed to carry out the proposed tests, distributed between men and women, the women with 127 individuals. Men, on the other hand, stood out in all physical tests. By calculating the partial correlation coefficient between all variables with an answer and as a too significant test, it was possible to support the construction of a correlated theoretical model as variables of interest both directly and as mediated by partiality relations, until they are associated or not with the outcome "walking speed". It was found, therefore, that studies on the functional performance of the elderly should consider sex, marital status, body mass index, means of locomotion and maximum inspiratory pressure as guidelines. Personal aspects (age and income), behavioral aspects / health status (fear of falling, quantity of drugs consumed, multicomorbidities and level of physical activity), peripheral muscle strength (handgrip strength and maximum one-repetition strength) and strength muscular respiratory (maximum expiratory pressure) are the variants that can be indirectly associated with the results.
