This study aimed to evaluate the discriminative capacity of total and segmental body composition variables to identify muscle weakness and low physical performance in older adults. Materials and Methods: A cross-sectional study was conducted in 268 community-dwelling older adults (72.2 \u00b1 8.2 years; 81.3% women). Body composition (lean mass, fat mass, and bone mineral content [BMC], total and segmental) was assessed using dual-energy X-ray absorptiometry. Muscle weakness was assessed by handgrip strength (\u226427 kg in men; \u226416 kg in women), and low physical performance by the Short Physical Performance Battery \u22648. Sex-stratified receiver operating characteristic (ROC) analyses were performed. Results: No significant differences were found between sexes for age (p = 0.307) or body mass index (p = 0.892). However, men exhibited significantly higher waist circumference (105.2 \u00b1 11.9 vs. 97.8 \u00b1 12.4 cm; p &lt; 0.001) and handgrip strength (30.3 \u00b1 6.8 vs. 18.3 \u00b1 4.6 kg; p &lt; 0.001) than women. Regarding body composition, men presented higher total lean mass (50.4 \u00b1 6.9 vs. 37.2 \u00b1 4.6 kg; p &lt; 0.001) and total bone mineral content (2666 \u00b1 483 vs. 1940 \u00b1 286 g; p &lt; 0.001). Conclusions: Body composition variables showed higher discriminative capacity for muscle weakness than for low physical performance. The ability of lean mass and BMC to identify low physical performance was modest in both sexes, suggesting that structural body composition variables alone may be insufficient to discriminate complex functional impairment in older adults.<\/jats:p>","DOI":"10.3390\/medicina62040684","type":"journal-article","created":{"date-parts":[[2026,4,6]],"date-time":"2026-04-06T04:10:27Z","timestamp":1775448627000},"page":"684","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond Adiposity: Lean Mass and Bone Mineral Content as Markers of Muscle Weakness and Physical Performance in Older Adults"],"prefix":"10.3390","volume":"62","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7013-3894","authenticated-orcid":false,"given":"Yeny","family":"Concha-Cisternas","sequence":"first","affiliation":[{"name":"Escuela de Kinesiolog\u00eda, Facultad de Salud, Universidad Santo Tom\u00e1s, Talca 3460000, Chile"},{"name":"Vicerrector\u00eda de Investigaci\u00f3n e Innovaci\u00f3n, Universidad Arturo Prat, Iquique 1100000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7001-9004","authenticated-orcid":false,"given":"Eduardo","family":"Guzm\u00e1n-Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Escuela de Kinesiolog\u00eda, Facultad de Salud, Universidad Santo Tom\u00e1s, Talca 3460000, Chile"},{"name":"Escuela de Pedagog\u00eda en Educaci\u00f3n F\u00edsica, Facultad de Educaci\u00f3n, Universidad Aut\u00f3noma de Chile, Talca 3460000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6173-1104","authenticated-orcid":false,"given":"Walter","family":"Sep\u00falveda Loyola","sequence":"additional","affiliation":[{"name":"Faculty of Health and Social Sciences, Center for Research in Biological and Chemical Sciences, Universidad de Las Am\u00e9ricas (UDLA), Santiago 7500975, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3853-6439","authenticated-orcid":false,"given":"Lincoy\u00e1n","family":"Fern\u00e1ndez Huerta","sequence":"additional","affiliation":[{"name":"Escuela de Kinesiolog\u00eda, Facultad de Ciencias de la Rehabilitaci\u00f3n y Calidad de Vida, Universidad San Sebasti\u00e1n, Concepci\u00f3n 4030000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0004-3089","authenticated-orcid":false,"given":"Felipe","family":"Montalva Valenzuela","sequence":"additional","affiliation":[{"name":"Escuela de Entrenador en Actividad F\u00edsica y Deporte, Facultad de Ciencias Humanas, Universidad Bernardo O\u2019Higgins, Santiago 8370040, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6190-938X","authenticated-orcid":false,"given":"Exal","family":"Garcia-Carrillo","sequence":"additional","affiliation":[{"name":"Department of Physical Activity Sciences, Faculty of Education Sciences, Universidad Cat\u00f3lica del Maule, Talca 3480112, Chile"},{"name":"Department of Physical Activity Sciences, Universidad de Los Lagos, Osorno 5290000, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6003-5107","authenticated-orcid":false,"given":"Iv\u00e1n","family":"Molina M\u00e1rquez","sequence":"additional","affiliation":[{"name":"Facultad de Educaci\u00f3n, Pedagog\u00eda en Educaci\u00f3n F\u00edsica, Universidad Adventista de Chile, Chill\u00e1n 3780000, Chile"},{"name":"Programa de Doctorado en Ciencias de la Actividad F\u00edsica Universidad, Cat\u00f3lica del Maule, Talca 34809112, Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9311-6576","authenticated-orcid":false,"given":"Rodrigo","family":"Ya\u00f1ez-Sep\u00falveda","sequence":"additional","affiliation":[{"name":"Facultad de Educaci\u00f3n y Ciencias Sociales, Universidad Andr\u00e9s Bello, Vi\u00f1a del Mar 2200055, Chile"},{"name":"School of Medicine, Universidad Esp\u00edritu Santo, Samborond\u00f3n 092301, Ecuador"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,3]]},"reference":[{"key":"ref_1","unstructured":"Toldr\u00e1, F.
