M. Kim and S. Shinkai

Geriatr Gerontol Int. 2017 [Epub ahead of print]

The present study compared the performance of the Jamar and Smedley dynamometers for the measurement of grip strength, and the two dynamometers were used to determine the prevalence rate of weakness in a large, community-dwelling, older adult population, based on different diagnostic criteria.

 

Resveratrol enhances exercise-induced cellular and functional adaptations of skeletal muscle in older men and women

S.E. Alway, J.L. McCrory, K. Kearcher,et al.

J Gerontol A Biol Sci Med Sci. 2017;72(12):1595-1606.

Data obtained indicate a novel anabolic role of resveratrol in exercise-induced adaptations of older persons and this suggests that resveratrol combined with exercise might provide a better approach for reversing sarcopenia than exercise alone.

 

Vitamin B12 deficiency might be related to sarcopenia in older adults

E.A. Bulut, P. Soysal, A.E. Aydin, et al.

Exp Gerontol. 2017; 95:136-140

The aim of this study is to evaluate the relationship between vitamin B12 deficiency and sarcopenia in older adults.

The loss of skeletal muscle mass, strength, and function with age are contributing risk factors for the onset of sarcopenia, frailty, osteoporosis, fractures, and mortality. For the first time in a northern European population, it has been observed a significant positive association between the Mediterranean diet score and FFM% (fat-free mass / weight × 100) and leg explosive power (LEP, watts/kg) in healthy women that are potentially clinically relevant, independent of the factors known to influence muscle outcomes. These findings emphasize the potential role for overall diet quality based on the Mediterranean diet in the prevention of age-related loss of skeletal muscle outcomes.

Use of the frailty index in evaluating the prognosis of older people in Beijing: A cohort study with an 8-year follow-up.

L. Ma, L. Zhang, Z. Tang et al.

Arch Gerontol Geriatr. 2016 ;64:172-7

The present study aimed to evaluate the prevalence of frailty and determine if the frailty index, a comprehensive geriatric assessment, was associated with the prognosis of older people in a Chinese population.

Results obtained suggests that the frailty index increases with age, and may be a significant tool for evaluation of the prognosis of older people in China.
