Age-Related Changes in Physical Function in Community-Dwelling People Aged 50-79 Years

Abstract

Abstract.[Purpose] We aimed to obtain the mean values for physical function tests in healthy communitydwelling people aged 50-79 years and to compare these values between age decades. [Subjects and Methods] We recruited 172 healthy community-dwelling people, who provided their written consent. Grip strength (GS), isometric knee extension torque (IKET), and the times for performing the sit-to-stand test (STS) and timed up-and-go test (TUG) were used as indicators of physical function. Maximum force (Fmax) and maximum power (Pmax) were measured by asking the subjects to perform the countermovement jump on a force platform system. The mean values were calculated and compared between different age decades by one-way analysis of variance. [Results] In men, all the measurements showed significant differences among different age decades; moreover, GS, IKET, Fmax, and Pmax decreased, while the time required for performing the STS and TUG increased with age. In women, GS, IKET, Fmax, and Pmax decreased, while the time required for performing the TUG increased with age. However, the time required for performing the STS did not differ across age groups in women. [Conclusion] The target values for physical function tests in people aged 50-79 years were established, and they were found to change with age.

Reference values for the Timed Up and Go test in healthy Japanese elderly people: Determination using the methodology of meta‐analysis

“…A total of 12 studies fulfilled the inclusion criteria: eight studies 13,[19][20][21][22][23][24][25] provided data on maximum effort (Table 1), and five studies 14,22,[27][28][29] provided data on the usual pace (Table 2). Studies with maximum effort data involved 2903 subjects (men 1083, women 1820), and studies with usual pace data involved 2396 subjects (men 815, women 1343, unknown 238).…”

Angiotensin-II blockage, muscle strength, and exercise capacity in physically independent older adults

“…This marked increase in life expectancy increases the morbidity from chronic diseases 2 ) , depression 3 ) , and worsens physical performance and quality of life 4 ) . Besides, ageing may affect physical performance of older adults, evoking negative impacts on their behavior and consequent changes in lifestyle, causing them to become dependent 5 ) . Several studies have reported that the loss of functional capacity in elderly people is usually related to the presence and complexity of comorbidities 6 ) .…”

The relationship between anthropometry and hand grip strength among elderly Malaysians

“…It is common knowledge that an individual's height (Kenny et al, 2008), weight (Kenny et al, 2008), body mass index (Corish and Kennedy, 2003) and muscle strength (Tsubaki et al, 2010) will decrease with ageing. They have shown that the decrease in muscle size is positively correlated with a decrease in hand grip strength.…”
