Correlação entre os testes da caminhada, marcha estacionária e TUG em hipertensas idosas

Abstract

© Revista Brasileira de FisioterapiaCorrelation between the walk, 2-minute step and tug tests among hypertensive older womenCorrelação entre os testes da caminhada, marcha estacionária e tug em hipertensas idosas Pedrosa R, Holanda g AbstractBackground:The increase in chronic diseases among older adults, especially systemic arterial hypertension, a disease that is closely related to declining functional capacity, has created the need to study methods for activity evaluation in order to detect functional capacity levels, prescribe exercises and monitor motor and cardiovascular function. The Six-Minute Walk Test (6MWT), Two-MinuteStep Test (2MST) and Timed Up and Go Test (TUG) are indicated for such evaluations. Studies among healthy older adults have shown associations between these tests, thus aiding the evaluation of functional capacity. However, there are no studies on the relationships between the 6MWT, 2MST and TUG among hypertensive individuals, thus justifying the present research. Objectives: To investigate whether there is any association between aerobic endurance and functional mobility among hypertensive older women.Methods: This was a cross-sectional observational and analytical study on 32 hypertensive older women who were evaluated using the 6MWT, 2MST and TUG. Results: There was a moderate positive correlation between the 6MWT and 2MST (r=0.36; p=0.04), and there were moderate negative correlations between the 6MWT and TUG (r=-0.59; p=0.000) and between the 2MST and TUG (r=-0.66; p=0.000). Conclusions: For hypertensive older women, the 6MWT can be replaced by the 2MST; the same applied to healthy older adults. Regarding the correlation between the 6MWT, 2MST and TUG, it can be concluded that there is a close relationship between cardiovascular endurance and functional mobility. When there is lower cardiovascular endurance, there is precarious functional mobility and vice versa.Key words: hypertension; aging; physical fitness. ResumoContextualização: O aumento de doenças crônicas em idosos, principalmente da Hipertensão Arterial Sistêmica, doença intimamente relacionada ao declínio da capacidade funcional, determina a necessidade do estudo de métodos de avaliação da realização das atividades, possibilitando detecção de níveis de capacidade funcional, prescrição de exercícios e acompanhamento das funções cardiovascular e motora. O teste da caminhada de 6 minutos (TC6'), o teste da Marcha Estacionária de 2 minutos (TME2') e o teste Timed Up and Go (TUG) são indicados para esta avaliação. Estudos em idosos saudáveis mostram a associação entre esses testes, facilitando a avaliação da capacidade funcional. Porém, em hipertensos, não existem estudos que avaliem a relação entre TC6', TME2'e TUG, justificando a realização desta pesquisa. Objetivos: Verificar se existe associação entre endurance aeróbia e a mobilidade funcional em idosas hipertensas. Métodos: Estudo observacional, analítico e transversal, com 32 hipertensas idosas, avaliadas por meio do TC6', TME2' e TUG. Resultados: Houve correlação positiv...

Exercise training program based on minimum weekly frequencies: effects on blood pressure and physical fitness in elderly hypertensive patients

“…However, these results were similar to or slightly lower than the results from other studies involving elderly patients with AH 27,28 , which suggests that AH is a chronic condition that can be associated with decreased motor capacity and physical fitness. Second, it is also interesting that the exercise protocol was effective in quantitatively improving the performance of muscle strength, balance, and aerobic capacity tests, as well as increasing the frequency of participants who achieved the range of reference values for muscle strength and aerobic capacity 20 .…”

Estudo comparativo da capacidade funcional e qualidade de vida entre idosos com osteoartrite de joelho obesos e não obesos

“…Para aplicação dos testes foram seguidas instruç ões padronizadas, já descritas na literatura. [13][14][15][16] Os testes foram o Timed Up and Go (TUG), 13 velocidade da marcha 14 e caminhada de seis minutos (TC6 ). 15,16 Para avaliação da QV, foram usados dois questionários, o Westerm Ontario and McMaster Universities (Womac) e o genérico SF-36 -Medical Outcomes Study 36-Item Short-Form Health Survey, ambos na versão brasileira já adaptados e validados no Brasil.…”

Variables Explaining Health-Related Quality of Life in Community-Dwelling Older Adults

“…The 2-minute step test adequately measures cardiovascular fi tness of the individual, 16 has a moderate correlation ( r = 0.73) with the 1-mile walk test, 18 and a fair correlation ( r = 0.36) to the 6-minute walk test in older women with hypertension. 20 The chair sit-and-reach and back scratch tests assess lower body (primarily hamstring) fl exibility and upper body fl exibility, respectively. 17 , 18 Measurement of height and weight to determine BMI is commonly used to identify health risks of the individual and is validated by the American College of Sports Medicine.…”
