ResumoIntrodução: Define-se "dupla tarefa" como a capacidade de efetivar uma ação primordial incorporada a uma segunda atividade. Em idosos, é presumível que a execução de ações simultâneas comprometa o equilíbrio postural, favorecendo quedas nesta população. AbstractIntroduction: Dual task can be defined as the ability to perform a primary action embedded in a second activity. In the elderly, it is presumed that the performance of concurrent actions disturb the postural balance, favoring falls in this population. Aims: To evaluate the effect of dual tasks in functional mobility of active seniors and correlate the time used for its realization with the individual's age. Methods: Cross-sectional, observational study with a convenience sample. Nineteen elderly from Universidade Aberta à Terceira Idade, Universidade Federal do Triângulo Mineiro, Minas Gerais state, Brazil, aged between 60 and 87 years, classified as physically active by the International Physical Activity Questionnaire (IPAQ) and with a minimum score that reaches 23 points on the Mini-Mental State Examination (MMSE) were evaluated during 9 sequential tests. The first one required a single task, which was represented by the Timed Up & Go (TUG) test, used to assess functional mobility of seniors. TUG was repeated in all other tests, in which was included a second action -manual activity in two tests and cognitive activity in six tests. Results: The elderly spent longer period performing associated tasks considering both motor and motor-cognitive combined actions when compared with time spent during the simple task. Positive correlation between age and the tests that incorporate cognitive activity to achieve the TUG was established. Conclusion: Physically active seniors require a longer period to perform the dual motor task involving distinct functions and coordinates between the upper limbs, and the same occurs for the performance of motor-cognitive dual tasks. The higher the age, the greater the time to perform double tasks, especially when associated with activities requiring short-term memory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
