How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Sarcopenia: Its assessment, etiology, pathogenesis, consequences and future perspectives (2008, background): “For example, after 50 years of age, muscle mass is reported to decline at an annual rate of approximately 1 to 2% (4), but strength declines at 1.”
Sarcopenia, Dynapenia, and the Impact of Advancing Age on Human Skeletal Muscle Size and Strength; a Quantitative Review (2012, background): “This reinforces the notion of a clear dissociation between loss of muscle and loss of strength (Hughes et al., 2002; Delmonico et al., 2009).”
The loss of skeletal muscle strength, mass, and quality in older adults: the health, aging and body composition study. (2006, background): “Hughes and colleagues (29) also reported that changes in muscle mass explained only 5% of the changes in strength.”
Low vitamin D and high parathyroid hormone levels as determinants of loss of muscle strength and muscle mass (sarcopenia): the Longitudinal Aging Study Amsterdam. (2003, background): “Change in muscle mass is known to be highly correlated with change in body weight (38).”
Excessive Loss of Skeletal Muscle Mass in Older Adults With Type 2 Diabetes (2009, result): “The finding of our study on sex difference is very consistent with previous studies showing that declines in muscle mass were almost always greater in men than in women (16,17).”
