This study examined the associations between musculotendinous morphology and functional movements, flexibility, and balance ability. Ninety-nine older women (66.6 \u00b1 4.6 years, body mass index 23.5 \u00b1 3.3 kg\u2219m\u20132) were recruited from Chonburi Province, Thailand. During one 90-min visit, muscle ultrasound imaging of vastus lateralis, biceps femoris, and medial gastrocnemius muscles, and tendon ultrasonography of the Achilles tendon and patellar tendon were performed. Measures were also obtained for the straight leg raise, passive dorsiflexion, balance, and functional tests (Five Times Sit to Stand (5TSTS), Timed Up and Go (TUG), 10-Meter Fast Walk Test (10-MFWT), and 6-Minute Walk Test (6-MWT)). The results specify that functional movement performance correlates most strongly with medial gastrocnemius muscle thickness (5TSTS (r = \u22120.26), TUG (r = \u22120.44), 10-MFWT (r = 0.41), and 6-MWT (r = 0.48) all p &lt; 0.05) and that vastus lateralis muscle thickness and medial gastrocnemius muscle thickness correlate positively with balance ability (r = 0.24, 0.34; p &lt; 0.05) and negatively with fear of falling. It appears that muscle mass, rather than other morphological parameters, such as muscle quality or fascicle length, is the main factor affecting the susceptibility of older women to frailty.<\/jats:p>","DOI":"10.3390\/ijerph192316099","type":"journal-article","created":{"date-parts":[[2022,12,2]],"date-time":"2022-12-02T01:44:46Z","timestamp":1669945486000},"page":"16099","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Associations between Muscle-Tendon Morphology and Functional Movements Capacity, Flexibility, and Balance in Older Women"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0521-7607","authenticated-orcid":false,"given":"Pornpimol","family":"Muanjai","sequence":"first","affiliation":[{"name":"Department of Physical Therapy, Allied Health Sciences Faculty, Burapha University, Chonburi 20131, Thailand"},{"name":"Exercise and Nutrition Innovation and Sciences Research Unit, Burapha University, Chonburi 20131, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juntip","family":"Namsawang","sequence":"additional","affiliation":[{"name":"Department of Physical Therapy, Allied Health Sciences Faculty, Burapha University, Chonburi 20131, Thailand"},{"name":"Exercise and Nutrition Innovation and Sciences Research Unit, Burapha University, Chonburi 20131, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danguole","family":"Satkunskien\u0117","sequence":"additional","affiliation":[{"name":"Institute of Sport Science and Innovations, Lithuanian Sports University, 44221 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sigitas","family":"Kamandulis","sequence":"additional","affiliation":[{"name":"Institute of Sport Science and Innovations, Lithuanian Sports University, 44221 Kaunas, Lithuania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Rogeri, P.S., Zanella, R., Martins, G.L., Garcia, M.D.A., Leite, G., Lugaresi, R., Gasparini, S.O., Sperandio, G.A., Ferreira, L.H.B., and Souza-Junior, T.P.
