Cross-sectional associations of dietary and circulating magnesium with skeletal muscle mass in the EPIC-Norfolk cohort

R.P.G. Hayhoe, M.A.H. Lentjes, A.A. Mulligan, et al.

Clin Nutr. 2018 Jan 30. pii: S0261-5614(18)30015-3. doi: 10.1016/j.clnu.2018.01.014. [Epub ahead of print]

This study demonstrated strong associations between dietary magnesium intake, but not serum magnesium levels, and indices of skeletal muscle mass in a UK population of middle to older-aged adults, highlighting the likely importance of dietary magnesium for optimal muscle health in this population.

 

Sex differences in the effect of fish-oil supplementation on the adaptive response to resistance exercise training in older people: a randomized controlled trial

M. Da Boit, R. Sibson, S. Sivasubramaniam, et al.

Am J Clin Nutr. 2017;105(1):151-158

Long-chain n-3 PUFA supplementation augments the increases in muscle function and quality in older women but not in older men after resistance exercise training.

Prevalence of muscle weakness based on different diagnostic criteria in community-dwelling older adults: a comparison of grip strength dynamometers

M. Kim and S. Shinkai

Geriatr Gerontol Int. 2017;17(11)2089-2095

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.

 

Benefits of resistance training in physically frail elderly: a systematic review

P. Lopez, R.S. Pinto, R. Radaelli, et al.

Aging Clin Exp Res. 2017 Nov 29. doi: 10.1007/s40520-017-0863-z. [Epub ahead of print]

Exercise is one of the most important components in frailty prevention and treatment. Therefore, we systematically reviewed the effect of resistance training (RT) alone or combined with multimodal exercise intervention on muscle hypertrophy, maximal strength, power output, functional performance, and falls incidence in physically frail elderly.
