Skeletal muscle indices were calculated by dividing appendicular lean mass by height or weight. Apart from this, we adjusted appendicular lean mass for body mass index, body surface area or waist\u2010to\u2010height ratio, which we then named the qualitative muscle mass index. Skeletal muscle function deficit was defined as a combination of weakness and slowness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Qualitative muscle indices were closely associated with physical capabilities. Receiver operating characteristic and logistic analyses showed that qualitative muscle indices had significantly greater discriminatory powers regarding low muscle function than did the height\u2010adjusted index in both men and women, and even showed higher discriminatory potentials than the weight\u2010adjusted index in men (all <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). The cut\u2010off values of qualitative muscle indices of body mass index\u2010, body surface area\u2010, and waist\u2010to\u2010height ratio\u2010adjusted indices for identifying functional deficits were 0.760, 11.40 and 34.18 for men, and 0.530, 8.91 and 23.07 for women, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The present study suggests that qualitative muscle indices are more accurate in predicting low muscle function than are height\u2010 and weight\u2010adjusted indices, because they consider anthropometric characteristics as part of the definition. The results might provide new avenues for conceptualizations of sarcopenia accompanied by obesity, and can be used as ethnic\u2010specific reference values of muscle mass indices based on functional outcome in an elderly Korean\/Asian population. <jats:bold>Geriatr Gerontol Int 2017;
