          Abstract

          RESUMO A fragilidade é uma condição instável relacionada ao declínio funcional, que afeta a interação do indivíduo com o ambiente, podendo causar limitação no desempenho das atividades de vida diária e perda de autonomia. O objetivo deste estudo foi realizar um aprofundamento teórico sobre os efeitos do exercício físico em idosos fragilizados. Trata-se de uma revisão sistemática de estudos publicados entre 2011 e 2016 nas bases de dados Medline, PubMed, PEDro, SciELO e Lilacs. Após a busca de dados, 12 artigos foram incluídos na pesquisa, os quais salientam os efeitos positivos do exercício físico sobre a fragilidade, enfatizando o treinamento multicomponente com regularidade de duas a três vezes por semana. Pode-se concluir que os exercícios físicos trazem efeitos benéficos para os idosos fragilizados quanto aos aspectos físicos e cognitivos e na qualidade de vida.

          ABSTRACT Frailty is an unstable condition related to functional decline, which affects the individual’s interaction with the environment and may cause limitation in the activities of daily living and result in loss of autonomy. This study aimed to provide a theoretical background on the effects of physical exercise on frail older people. This is a systematic review of studies published between 2011 and 2016 in the Medline, PubMed, PEDro, SciELO and Lilacs databases. After data search, 12 articles were included in the investigation, which highlight the positive effects of physical exercise on frailty, emphasizing multicomponent training with regularity of two to three times a week. We can conclude that physical exercises bring beneficial effects to frail older people in terms of quality of life and physical and cognitive aspects.

          Multicomponent exercises including muscle power training enhance muscle mass, power output, and functional outcomes in institutionalized frail nonagenarians.

          This randomized controlled trial examined the effects of multicomponent training on muscle power output, muscle mass, and muscle tissue attenuation; the risk of falls; and functional outcomes in frail nonagenarians. Twenty-four elderly (91.9 ± 4.1 years old) were randomized into intervention or control group. The intervention group performed a twice-weekly, 12-week multicomponent exercise program composed of muscle power training (8-10 repetitions, 40-60 % of the one-repetition maximum) combined with balance and gait retraining. Strength and power tests were performed on the upper and lower limbs. Gait velocity was assessed using the 5-m habitual gait and the time-up-and-go (TUG) tests with and without dual-task performance. Balance was assessed using the FICSIT-4 tests. The ability to rise from a chair test was assessed, and data on the incidence and risk of falls were assessed using questionnaires. Functional status was assessed before measurements with the Barthel Index. Midthigh lower extremity muscle mass and muscle fat infiltration were assessed using computed tomography. The intervention group showed significantly improved TUG with single and dual tasks, rise from a chair and balance performance (P < 0.01), and a reduced incidence of falls. In addition, the intervention group showed enhanced muscle power and strength (P < 0.01). Moreover, there were significant increases in the total and high-density muscle cross-sectional area in the intervention group. The control group significantly reduced strength and functional outcomes. Routine multicomponent exercise intervention should be prescribed to nonagenarians because overall physical outcomes are improved in this population.

              The association between sedentary behaviour, moderate-vigorous physical activity and frailty in NHANES cohorts.

              (1) To examine how sedentary behaviour and moderate-vigorous (MVPA) are each experienced during the day across different levels of frailty; (2) estimate and compare the extent to which high levels of sedentary behaviour and low levels of MVPA are associated with increased frailty and self-reported health, disability and healthcare utilization.
