Methods: Patients with various MQIs (strength-to-mass ratios) were stratified into two groups. Physical-muscular aspects were assessed using body mass index (BMI), a Simple Questionnaire to Rapidly Diagnose Sarcopenia (SARC-F), and handgrip strength. Cognitive aspects were assessed using Mini-Mental State Examination (MMSE), Trail Making Test, Stroop Test, verbal fluency, and dual-task performance. Seventy-nine older adults (73 \u00b1 9 years) of both sexes completed the tests. Results: BMI, SARC-F, handgrip strength, MMSE, Stroop Test (L1), semantic verbal fluency (animals), and dual-task outcomes differed between MQI groups (p \u2264 0.05) and were associated with MQI in regression analyses. In the adjusted model, BMI, handgrip strength, and dual-task walking time were independently associated with MQI (adjusted R2 = 0.514). Conclusion: Lower-limb MQI was associated with markers of sarcopenia and cognitive\/dual-task performance in community-dwelling older adults.<\/jats:p>","DOI":"10.3390\/bioengineering13030265","type":"journal-article","created":{"date-parts":[[2026,2,26]],"date-time":"2026-02-26T10:33:02Z","timestamp":1772101982000},"page":"265","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association Between Lower-Limb Muscle Quality, Cognitive Function and Sarcopenia in Older Adults: Cross-Sectional Study"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4981-733X","authenticated-orcid":false,"given":"Arthur N.","family":"Arrieiro","sequence":"first","affiliation":[{"name":"Departamento de Fisioterapia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina 39100-000, MG, Brazil"},{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Ci\u00eancias da Sa\u00fade\u2014PPGCS, Universidade Federal dos Vales do Jequitinhonha e Mucuri\u2014UFVJM, Diamantina 39100-000, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0227-3884","authenticated-orcid":false,"given":"Redha","family":"Taiar","sequence":"additional","affiliation":[{"name":"MAT\u00e9riaux et Ing\u00e9nierie M\u00e9canique\u2014MATIM, Universit\u00e9 de Remis Champagne France, 51100 Reims, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7872-7109","authenticated-orcid":false,"given":"Luana A.","family":"Soares","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina 39100-000, MG, Brazil"},{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Reabilita\u00e7\u00e3o e Desempenho Funcional\u2014PPGReab, Universidade Federal dos Vales do Jequitinhonha e Mucuri\u2014UFVJM, Diamantina 39100-000, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4996-6979","authenticated-orcid":false,"given":"Jousielle M.","family":"Santos","sequence":"additional","affiliation":[{"name":"Departamento de Fisioterapia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, Diamantina 39100-000, MG, Brazil"},{"name":"Programa de P\u00f3s-Gradua\u00e7\u00e3o em Reabilita\u00e7\u00e3o e Desempenho Funcional\u2014PPGReab, Universidade Federal dos Vales do Jequitinhonha e Mucuri\u2014UFVJM, Diamantina 39100-000, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5279-7643","authenticated-orcid":false,"given":"Fabiana S.
