Fig. 3From: Prevalence of sarcopenia under different diagnostic criteria and the changes in muscle mass, muscle strength, and physical function with age in Chinese old adultsChanges of muscle mass, muscle strength and physical function with age. A and B show that muscle mass (assessed by SMI) is not in parallel with muscle strength (assessed by grip strength) and function (assessed by gait speed), and the decline of muscle strength and function is more significant than the decline of muscle mass. C shows that muscle strength is in parallel with the decline of function. MM: muscle mass; MS: muscle strength; PF: physical functionBack to article page
