Physical function was evaluated using the Senior Fitness Test Battery. PhA was measured by electrical bioimpedance at 50 khz, and body composition parameters were also registered. Results showed that PhA significantly correlated with all physical fitness tests, except for arm curls. Regarding the results of the multivariate analysis, three models were created: Model 1, formed by a dependent variable \u201cPhA\u201d and two predictor variables \u201c8 ft up-and-go\u201d and \u201c6 min walk\u201d; Model 2, formed by a dependent variable \u201cPhA\u201d and three predictor variables \u201c8 ft up-and-go\u201d, \u201c6 min walk\u201d and \u201c30-s chair stand\u201d; and Model 3, formed by a dependent variable \u201cPhA\u201d and four predictor variables \u201c8 ft up-and-go\u201d, \u201c6 min walk\u201d, \u201c30-s chair stand\u201d and \u201carm curl\u201d. Results showed that predictor variables had a significant influence on the PhA for all three models (Model 1: p = 0.001, 12.5%; Model 2: p = 0.002, 12.9%; and Model 3: p = 0.005, 13.1%). For women, Model 1 showed a significant influence of predictor variables on the PhA (p = 0.030, 9.3%). The results for men in Models 1, 2 and 3 showed significant influences on the PhA (p = 0.002, 31.2%; p = 0.006, 31.6%; and p = 0.016, 31.6%; respectively). This study confirmed previous studies regarding to the relationship between PhA and physical function. It also indicates that PhA could be an excellent predictor of physical function.<\/jats:p>","DOI":"10.3390\/ijerph192114615","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T10:53:06Z","timestamp":1667904786000},"page":"14615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Phase Angle as a Predictor for Physical Function in Institutionalized Independent Older Adults"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3036-2526","authenticated-orcid":false,"given":"Ana","family":"Morais","sequence":"first","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3556-2380","authenticated-orcid":false,"given":"Soraia","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1524-5601","authenticated-orcid":false,"given":"Alexandre Duarte","family":"Martins","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Life Quality Research Centre, 2040-413 Rio Maior, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7780-3942","authenticated-orcid":false,"given":"Pablo","family":"Tomas-Carus","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"}]},{"given":"Jos\u00e9","family":"Marmeleira","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5254-7409","authenticated-orcid":false,"given":"Jose A.","family":"Parraca","sequence":"additional","affiliation":[{"name":"Departamento de Desporto e Sa\u00fade, Escola de Sa\u00fade e Desenvolvimento Humano, Universidade de \u00c9vora, 7004-516 \u00c9vora, Portugal"},{"name":"Comprehensive Health Research Centre (CHRC), University of \u00c9vora, 7004-516 \u00c9vora, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104787","DOI":"10.1016\/j.archger.2022.104787","article-title":"Effects of exercise programs on phase angle in older adults: A systematic review and meta-analysis","volume":"103","author":"Martins","year":"2022","journal-title":"Arch.
