Resumo: | Introduction: Aging is the natural course of human life and has repercussions on various structures and functions of body systems. Maintaining the muscle strength of the knee extensors and flexors becomes relevant for the performance of ADLs, and is often assessed using an isokinetic dynamometer. The a/agonist ratio is also given by this equipment, being a good indicator of muscle imbalances. Objectives: to analyze the influence of peak torque and power of the knee extensors and flexors on the functional performance of elderly people and to observe the interaction between the agonist/antagonist ratio and performance in functional tests. Methods: This is a cross-sectional study, in which elderly people from the community participated. The isokinetic variables analyzed were peak torque relative to body mass, mean power and agonist/antagonist ratio at speeds of 60º/s and 180º/s. The distribution frequency and descriptive analysis of the sample were used. To analyze the interaction between isokinetic variables and functional performance, Spearman's correlation test was used. A multivariate regression was performed considering isokinetic variables as independent variables, and functional performance variables as dependent. Results: 36 elderly people with a mean age of 60 years participated in the study, 29 women and 7 men. The agonist/antagonist ratio at 180º/s speed influenced the performance of the TUG test. The other variables showed no influence on the functional tests. Gait speed showed a significant positive correlation with the peak torque variable at 60º/s and 180º/s. Conclusion: isokinetic muscle strength can influence functional performance and the higher the agonist/antagonist ratio in elderly people, the better their performance in functional tests. Keywords: elderly people; muscle strength; functionality. |

Mantener la fuerza muscular de los extensores y flexores de la rodilla se vuelve relevante para realizar las AVD y, a menudo, se evalúa utilizando un dinamómetro isocinético. La relación antagonista/agonista también la da este equipo, siendo un buen indicador de desequilibrios musculares. Objetivos: analizar la influencia del torque pico y la potencia de los extensores y flexores de la rodilla en el desempeño funcional de ancianos y observar la interacción entre la relación agonista/antagonista y el desempeño en pruebas funcionales. Métodos: Se trata de un estudio transversal, en el que participaron ancianos de la comunidad. Las variables isocinéticas analizadas fueron el par pico relativo a la masa corporal, la potencia media y la relación agonista/antagonista a velocidades de 60º/s y 180º/s. Se utilizó la distribución de frecuencias y el análisis descriptivo de la muestra. Para analizar la interacción entre las variables isocinéticas y el rendimiento funcional, se utilizó la prueba de correlación de Spearman. Se realizó una regresión multivariante considerando las variables isocinéticas como variables independientes y las variables de desempeño funcional como dependientes. Resultados: Participaron del estudio 36 ancianos con edad media de 60 años, 29 mujeres y 7 hombres. La relación agonista/antagonista a una velocidad de 180º/s influyó en la realización de la prueba TUG. Las demás variables no mostraron influencia en las pruebas funcionales. La velocidad de la marcha mostró una correlación positiva significativa con la variable torque pico a 60º/s y 180º/s. Conclusión: la fuerza muscular isocinética puede influir en el rendimiento funcional y cuanto mayor sea la relación agonista/antagonista en las personas mayores, mejor será su rendimiento en las pruebas funcionales. Palabras clave: adultos mayores; fuerza muscular; funcionalidad.Introdução: O envelhecimento é o curso natural da vida humana e tem repercussões em diversas estruturas e funções dos sistemas do corpo. A manutenção da força muscular dos extensores e flexores do joelho torna-se relevante para a realização das AVD’s, sendo frequentemente avaliada através do dinamômetro isocinético. A razão antagonista/agonista também é dada por esse equipamento, sendo uma boa indicadora de desequilíbrios musculares. Objetivos: analisar a influência do pico de torque e potência dos extensores e flexores do joelho no desempenho funcional de pessoas idosas e observar a interação entre a razão agonista/antagonista e o desempenho nos testes funcionais. Métodos: Trata-se de um estudo transversal, no qual participaram pessoas idosas provenientes da comunidade. As variáveis isocinéticas analisadas foram pico de torque relativo à massa corporal, potência média e razão agonista/antagonista nas velocidades de 60º/s e 180º/s. Foi utilizada a frequência de distribuição e análise descritiva da amostra. Para analisar a interação entre as variáveis isocinéticas e o desempenho funcional, foi utilizado teste de correlação de Spearman. Foi realizada uma regressão linear multivariada considerando como variáveis independentes as variáveis isocinéticas, e como dependentes, as variáveis de desempenho funcional. Resultados: Participaram do estudo 36 pessoas idosas com média de idade de 60 anos, sendo 29 mulheres e 7 homens. A razão agonista/antagonista na velocidade de 180º/s influenciou a realização do teste TUG. As outras variáveis não demonstraram influência nos testes funcionais. A velocidade de marcha apresentou correlação positiva significativa com a variável pico de torque a 60º/s e 180º/s.Conclusão: A força muscular isocinética pode influenciar o desempenho funcional e, quanto mais alta a razão agonista/antagonista em pessoas idosas, melhor o desempenho destas em testes funcionaisUniversidade Católica de Brasília2023-08-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por Paresapplication/pdfhttps://portalrevistas.ucb.br/index.php/rbcm/article/view/1443610.31501/rbcm.v30i3.14436Revista Brasileira de Ciência e Movimento; v. 30 n. 3 (2022)0103-171610.31501/rbcm.v30i03reponame:Revista Brasileira de Ciência e Movimento (Online)instname:Universidade Católica de Brasília (UCB)instacron:UCBporhttps://portalrevistas.ucb.br/index.php/rbcm/article/view/14436/11572Copyright (c) 2023 Marina Danielle Senna Souza Souzainfo:eu-repo/semantics/openAccessSouza, Marina Danielle Senna SouzaLima de Souza, LeandroSantos Ferreira, Carlos ErnestoVidal Pereira, ThiagoCoelho Vilaça e Silva, Karla Helenada Silva Lima, Letíciade Oliveira Lima, Ana Caroline2023-06-28T23:47:00Zoai:ojs.portalrevistas.ucb.br:article/14436Revistahttp://portalrevistas.ucb.br/index.php/RBCMPRIhttp://portalrevistas.ucb.br/index.php/RBCM/oai||jr_lazer@yahoo.com.br2237-90020103-1716opendoar:2023-06-28T23:47Revista Brasileira de Ciência e Movimento (Online) - Universidade Católica de Brasília (UCB)false |
