It is intuitive to think that sarcopenia should be associated with declines in physical function though recent evidence questions this assertion. This study investigated the relationship between absolute and relative sarcopenia, with physical performance in 202 nonobese (mean BMI=26.6 kg/ht2) community-dwelling older (mean age =73.8±5.9years) adults. While absolute sarcopenia (appendicular skeletal mass (ASM)/ht2) was either not associated, or weakly associated with physical performance, relative sarcopenia (ASM/kg) demonstrated moderate (r=0.31tor=0.51,P<0.01) relationships with performance outcomes in both males and females. Knee extension strength (r=0.27) and leg extension power (r=0.41) were both related to absolute sarcopenia (P<0.001) in females and not in males. Strength and power were associated with relative sarcopenia in both sexes (fromr=0.47tor=0.67, P<0.001). The ratio of lean mass to total body mass, that is, relative sarcopenia, is an important consideration relative to physical function in older adults even in the absence of obesity. Stratifying these individuals into equal tertiles of total body fat revealed a trend of diminished regression coefficients across each incrementally higher fat grouping for performance measures, providing further evidence that total body fat modulates the relationship between sarcopenia and physical function.

Abstract Background and Purpose. The decline of physical function of older adults, associated with loss of independent living status, is a major public health concern. The purpose of this study was to examine the relationship of physical impairment and disability to performance of activities of daily living (ADL) among community-dwelling older adults. Subjects and Methods. Eighty-three community-dwelling older men who were referred to a comprehensive outpatient geriatric evaluation program (mean age=75.5 years, SD=7.0, range=64–97) were examined. Measurements of physical impairment (muscle force production, flexibility, and fitness) and physical disability (gait speed, stride length, risk for recurrent falls, and physical function) were recorded. Results. A stepwise linear regression was used to determine the relationship of physical impairments and disability measures with ADL. The results indicated that walking speed, fall risk, and muscle force contributed independently to the characterization of the activities of daily living of the community-dwelling older men studied (adjusted R2=.68; F=56.81; df=3,80; P&lt;.001). Using a principal components factor analysis, 4 domains were identified that explained 68.2% of the variance in performance of ADL: (1) mobility/fall risk=26.5%, (2) coordination=15%, (3) fitness=14.7%, and (4) flexibility=12.0%. Discussion and Conclusion. The identification of domains of physical function may be useful to physical therapists in the development of interventions targeted for physical impairments and disabilities that contribute to deficits in performance of ADL. Targeting interventions for physical impairments and disabilities related to function may improve the effectiveness of physical therapist interventions and reduce the loss of independence among community-dwelling older people.
