Association of the ACTN3 genotype and physical functioning with age in older adultsMatthew J Delmonico
Department of Epidemiology, University of Pittsburg, Pittsburg, PA, USA
J Gerontol A Biol Sci Med Sci 63:1227-34. 2008..The purpose of this study was to examine the association of the alpha-actinin-3 (ACTN3) R577X polymorphism on muscle function and physical performance in older adults...
Longitudinal study of muscle strength, quality, and adipose tissue infiltrationMatthew J Delmonico
Department of Epidemiology and Medicine, University of Pittsburgh, Pittsburgh, PA, USA
Am J Clin Nutr 90:1579-85. 2009..Sarcopenia is thought to be accompanied by increased muscle fat infiltration. However, no longitudinal studies have examined concomitant changes in muscle mass, strength, or fat infiltration in older adults...
