Background: Despite the growing importance of physical function in later life, there is still lack of information explaining the relationship between obesity, sarcopenic obesity and functional capacity in seniors. The objective of this study is to examine the influence of obesity and sarcopenic obesity on functional capacity.
Methods: 673 sedentary older women were recruited from 16 different districts and their body compositions as well as 5 different functional capacities (chair stand, arm curl, one leg stand, 2-min steps, and shoulder flexibility) were examined. Participants were classified into 4 groups by the way of Cogswell and Dietz’s sarcopenic obesity classification; Normal muscle+normal fat(Group-A), normal muscle +high fat(Group-B), low muscle+normal fat(Group-C), and low muscle+high fat(Group-D: Sarcopenic obese). GLM and LSD-test were conducted with SPSS 13.0.
Results: For 673 older women, mean age of 75, chair-stand (p<.05), arm curl (p<.001), one leg stand(p<.01), 2-min steps(p<.001) were associated with the level of muscle mass and fat mass. For chair stand, sarcopenic obese group has much lower score than that of Group-A and Group-B (p<.05). For arm curl, sarcopenic obese group has lower score that that of Group- A (p<.05). For One leg stand and 2-min steps show same results that sarcopenic obese group has lower score that that of Group A(normal muscle + normal fat) (p<.05).
Conclusions: We concluded that sarcopenic obese, percent fat affect functional capacity in sedentary older adults.
