“…Height has been shown to correlate with muscle strength cross-sectionally among healthy young and older adults [22] . In our previous study of an elderly male population [23] , we observed that greater height loss since age 25 years was related to strength loss during 7 years of followup. Height change might act as an overall marker for long-term changes in body composition.…”

Background: The aging process is associated with progressive declines in muscle strength, resulting in functional disability and reduced quality of life. Objective: The purpose of this epidemiological study was to examine the age-related loss of grip strength both cross-sectionally and longitudinally and the risk factors associated with the decline in muscle strength in a large population of community-living older women (aged 65–91 years). Methods: Clinical visits, including physical examinations and lifestyle assessment, were conducted at baseline and biennially afterwards for a total of 10 years of follow-up. The upper-body muscle strength was measured by grip strength using a hand-held dynamometer. Results: The muscle strength decreased cross-sectionally (n = 9,372) as well as longitudinally (n = 5,214), as age increased, and the decline in muscle strength measured during follow-up was greater than that measured cross-sectionally at baseline. The average loss of grip strength during 10 years of follow-up was 5.1 kg, equivalent to a rate of 2.4% decline per year, with the greatest loss seen in the oldest age group (80 years or older). Cross-sectional analysis revealed that the correlates of lower muscle strength included older age, greater weight, greater height loss since age 25 years, lower protein intake, difficulties in functional tasks, and lower physical activity. In longitudinal analysis, older age, baseline strength, weight and height loss during follow-up, difficulties in functional tasks, and lower physical activity were found to be significantly and independently associated with greater loss in grip strength during follow-up. Conclusions: Cross-sectional and longitudinal analyses of age-related loss of muscle strength yielded different rates of decline. In addition to older age and difficulties in functional tasks, a number of modifiable factors, including weight and physical activity, are associated with increased decline in muscle strength among older women.

“…In most studies, the development of sarcopenia is associated strongly with increased disability, gait and balance disorders, and mortality [6,7]. Muscle strength also declines with aging [8].…”

Frailty is a common condition in older people. It now can be objectively defined by the Fried criteria. When recognized, early intervention should begin with the institution of endurance, resistance, and balance exercises. In men with testosterone deficiency a trial of testosterone replacement should be considered. Vitamin D deficiency needs to be recognized and treated. Appropriate treatment of underlying diseases, such as anemia, diabetes mellitus, and congestive heart failure, are a key management principle. In people who have frailty aggressive health promotion and disease prevention techniques can lead to an inhibition of the downward spiral to disability.

“…The age-related decline in grip strength in adults has been reported in a number of previous longitudinal studies 2,20,[36][37][38][39] . However, the trajectory of grip strength with aging has been described as linear 36,40,41) or curved/quadratic 37,42,43) , and some studies have illustrated the slope with flexion points.…”
