Resumo: One of the problems that most concerns the elderly population is the falling, which can be caused by muscle fatigue. The objective of this study was to compare median electromyographic frequency values for the vastus lateralis muscle and the lateral portion of the gastrocnemius muscle (as parameters of electromyographic fatigue) in elderly people with and without a history of falls. A total of 20 healthy, physically active, elderly women who had or had not suffered falls were enrolled on the study. Median electromyographic signal frequencies were analyzed for the vastus lateralis muscle and the lateral portion of the gastrocnemius muscle in isometric contraction. ANOVA and Student’s t test were used for comparisons, to a cutoff of p ≤ 0.05. Median frequencies for the gastrocnemius and vastus lateralis muscles were both higher in the group with a history of falling, but without statistical significance. It was also observed that the rate of decline in median frequency was greater in the group with a history of falling. It can be concluded that elderly people with a history of falling have a greater tendency to fatigue of the gastrocnemius and vastus lateralis muscles than their peers with no history of falling.

O objetivo do estudo foi comparar os valores de frequência mediana, como um parâmetro de fadiga eletromiográfica, dos músculos vasto lateral e porção lateral do gastrocnêmio em idosos com e sem história de quedas. Participaram do estudo 20 idosas saudáveis, ativas fisicamente (que sofreram e não sofreram quedas). Analisou-se a frequência mediana do sinal eletromiográfico dos músculos vasto lateral e porção lateral do gastrocnêmio em isometria. As comparações foram feitas pela ANOVA e teste t de Student, considerando p ≤ 0,05. O músculo grastrocnêmio apresentou maiores Fmed no grupo caidor do que no não caidor, o mesmo acontecendo com o vasto lateral, sem significância estatística. Também foi possível observar que a taxa de queda dos valores da frequência foi maior no grupo caidor do que no não caidor. Pode-se concluir que há maior tendência de fadiga dos músculos gastrocnêmio e vasto lateral de idosos caidores.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Estadual Paulista Faculdade de Filosofia e Ciências Departamento de Fisioterapia e Terapia OcupacionalUniversidade Estadual Paulista Instituto de BiociênciasUniversidade Estadual Paulista Faculdade de Filosofia e Ciências Departamento de Fisioterapia e Terapia OcupacionalUniversidade Estadual Paulista Instituto de BiociênciasUniversidade Federal de Santa CatarinaUniversidade Estadual Paulista (Unesp)Silva, Lissara EllenPedroni, Cristiane Rodrigues [UNESP]Navega, Marcelo Tavella [UNESP]Scheicher, Marcos Eduardo [UNESP]2015-02-02T12:39:33Z2015-02-02T12:39:33Z2014-07-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article390-398application/pdfhttp://dx.doi.org/10.5007/1980-0037.2014v16n4p390Revista Brasileira de Cineantropometria & Desempenho Humano.
