It is unclear if this\u00a0method will improve the correlation between muscle cross-sectional area (CSA) and physical performance. We examined\u00a0the correlations between quadriceps muscle morphology parameters and physical performance outcomes in older women.\u00a0Material and methods: Twenty older women participated in this study. Ultrasound imaging was used to measure quadriceps\u00a0muscle CSA and echo intensity. Muscle CSA was expressed as an absolute value (cm2) and as a relative value normalized to\u00a0body mass (cm2\/kg). Physical performance was assessed from timed up\u2010and\u2010go and 6-min walk tests.Results: Relative CSA\u00a0was significantly related to timed up-and-go scores (r=-0.489, p=0.029) and 6-min walking speed (r=0.606, p=0.005), whereas\u00a0absolute CSA was not significantly associated with these performances (r=-0.231, p=0.327 and r=0.373, p=0.105). There was\u00a0a significant correlation between absolute CSA and body mass (r=0.456, p=0.043). There were also significant correlations\u00a0between echo intensity and timed up-and-go scores (r=0.556, p=0.011) and 6-min walking speed (r=-0.484, p=0.031).Conclusions:\u00a0Our study showed that relative CSA correlated better than absolute CSA with physical performance. These findings\u00a0support the need to normalize measurements of muscle CSA to body mass in older adults.<\/jats:p>","DOI":"10.11152\/mu-4324","type":"journal-article","created":{"date-parts":[[2024,1,30]],"date-time":"2024-01-30T18:41:46Z","timestamp":1706640106000},"page":"153","source":"Crossref","is-referenced-by-count":3,"title":["Influence of body mass normalization on the correlations between muscle cross-sectional area and physical performance outcomes in older women"],"prefix":"10.11152","volume":"26","author":[{"given":"Ty B","family":"Palmer","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bailey M","family":"Palmer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2024,6,21]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4324\/2312","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/4324\/2312","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,6,21]],"date-time":"2024-06-21T13:56:46Z","timestamp":1718978206000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/4324"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,6,21]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2024,6,21]]}},"URL":"https:\/\/doi.org\/10.11152\/mu-4324","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2024,6,21]]}}}
