BMC Geriatr. 2019;19(1):153

The aim of this study was to examine the impact of sarcopenia, and its underlying components, on independent ageing in a cohort study of very old men.

Involvement of plasma miRNAs, muscle miRNAs and mitochondrial miRNAs in the pathophysiology of frailty

Exp Gerontol. 2019;124:110637

microRNAs are the one of multiple epigenetic biomarkers that reflect functional changes in aged subject. In this review we analyze microRNAs as molecules involved in the control of the pathways leading to the development of frailty.

A high whey protein, vitamin D and E supplement preserves muscle mass, strength, and quality of life in sarcopenic older adults: A double-blind randomized controlled trial

Y. Bo, C. Liu, Z. Ji, et al.

Clin Nutr. 2019;38(1):159-164

Sarcopenia, an age-related decline of muscle mass, strength, and physical function, was associated with falls, frailty, and poor quality of life. The aim of the current study is to examine the effect of nutritional supplement containing whey protein, vitamin D and E on measures of sarcopenia.

The Effect of β-hydroxy-β-methylbutyrate (HMB) on Sarcopenia and Functional Frailty in Older Persons: A Systematic Review

J. Oktaviana, J. Zanker, S. Vogrin, et al.

J Nutr Health Aging. 2019;23(2):145-150

Beta-hydroxy-beta-methylbutyrate (HMB) has been shown to be effective and superior to other types of protein supplements to attenuate loss of muscle mass, strength and function, however, its benefits in sarcopenic and frail older people remain unclear.

We seek to determine the effect of HMB on muscle mass, strength and function in older people with sarcopenia or frailty by reviewing results from available randomized controlled trials (RCTs).

Effects of branched-chain amino acids and vitamin D supplementation on physical function, muscle mass and strength, and nutritional status in sarcopenic older adults undergoing hospital-based rehabilitation: A multicenter randomized controlled trial

I. Takeuchi, Y. Yoshimura, S. Shimaz, et al.

Geriatr Gerontol Int. 2019;19(1):12-17

The aim was to investigate the effects of branched-chain amino acids and vitamin D supplementation on physical function, muscle strength, muscle mass, and nutritional status in sarcopenic older adults undergoing hospital-based rehabilitation.

Higher dietary nitrate intake is associated with better muscle function in older women

M. Sim, J.R. Lewis, L.C. Blekkenhorst, et al.

J Cachexia Sarcopenia Muscle. 2019 Mar 24. doi: 10.1002/jcsm.12413. [Epub ahead of print]

The role of higher habitual nitrate intake as part of a typical diet on muscle function in ageing has not been investigated. In this article a cross-sectional study of relationships between dietary nitrate and measures of muscle function in older community-dwelling Australian women (n = 1420, ≥70 years) was undertaken.
