Frailty Assessment in the Cardiovascular Care of Older Adults (2013, background): “Muscle mass is a predictor of frailty and functional decline (86,87) and can be reliably measured by computed tomography, magnetic resonance, or dual-isotope x-ray absorptiometry (88).”
The loss of skeletal muscle strength, mass, and quality in older adults: the health, aging and body composition study. (2006, background): “Moreover, sarcopenia is related to functional impairment (12,13), disability (14,15), falls (16), and loss of independence (17) in older adults.”
Sarcopenia: Its assessment, etiology, pathogenesis, consequences and future perspectives (2008, background): “Contractility, motor unit recruitment or muscle metabolism is decreased in the presence of fat infiltration (164), and the excess fatty acids in the muscle fibers interferes with the normal cellular signaling (166).”
Intermuscular Fat: A Review of the Consequences and Causes (2014, background): “There is an increasing amount of evidence linking IMAT with mobility impairment in older adults [25, 27, 29, 30, 42, 43].”
Longitudinal study of muscle strength, quality, and adipose tissue infiltration. (2009, methodology): “The CSAs of muscle and IMF of the right thigh were measured at baseline at the level of the midfemur by using CTas previously described (3).”
Prognostic Value of Usual Gait Speed in Well‐Functioning Older People—Results from the Health, Aging and Body Composition Study (2005, methodology): “The fastest time of two trials (in m/s) was used for the present analyses.(13)”
Sarcopenia: Alternative Definitions and Associations with Lower Extremity Function (2003, result): “Together these studies lend support to the idea that low LM is associated with limitations in lower extremity function whether fat is considered in the definition or with subsequent adjustment for fat mass.(1,4,22,25) Other analytic approaches to account for both fat mass and LM and the effects on f”
Research Agenda for Frailty in Older Adults: Toward a Better Understanding of Physiology and Etiology: Summary from the American Geriatrics Society/National Institute on Aging Research Conference on Frailty in Older Adults (2006, background): “With development of research on macroscopic, microscopic, and functional changes in human tissues, there is now increasing evidence to indicate that fat infiltration of muscle may explain in part the discrepancy between mass and force.(22) Although the understanding of the natural causes, consequenc”

Muscle mass, muscle strength, and muscle fat infiltration as predictors of incident mobility limitations in well-functioning older persons. (2005, methodology): “Recent cross-sectional studies have shown that low muscle mass is associated with poor functional performance ( 3 ,4) and self-reported disability (4‐6).”
The FNIH Sarcopenia Project: Rationale, Study Description, Conference Recommendations, and Final Estimates (2014, background): “entirely consistent, the weight of evidence in communitydwelling older adults suggests that (i) low muscle mass is associated with weakness (3), (ii) weakness (now often referred to as “dynapenia”) (4) is strongly associated with function and disability (5,6), but (iii) low muscle mass alone is weak”
