The main purpose of this cross-sectional study was to explore whether PhA is associated with muscle quality and functional capacity in older women, regardless of total and regional body composition.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n A total of 125 older women\u201466.7 (4.7) years; 65.6 (10.9) kg body mass; 156.1 (5.2) cm height; 26.9 (4.0) kg\/m2<\/jats:sup> body mass index\u2014participated in this study. Anthropometric, PhA, body composition (whole-body dual-energy x-ray absorptiometry) and muscle quality (defined as total muscular strength per kilogram of appendicular lean soft tissue) were measured. The functional capacity was assessed by 4 tests: 10-m walk test, rising from sitting position, rising from ventral decubitus position, and rising from a chair and walking around the house. The summing z<\/jats:italic>-scores for the 4 tests was used as a continuous functional capacity score. Linear regression analysis was conducted to test whether PhA is related to the dependent variables (muscle quality and functional capacity), after adjusting for potential covariates.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n The PhA presented a small-to-moderate relationship with muscle quality (r<\/jats:italic> = 0.27; P<\/jats:italic> < .01) and functional capacity (r<\/jats:italic> = 0.31; P<\/jats:italic> < .01), respectively. These relationships remained significant after adjustment for age, lower limb lean soft tissue, and total fat mass for muscle quality (\u03b2= 0.55; P<\/jats:italic> < .01) and functional capacity (\u03b2= 1.38; P<\/jats:italic> < .01).<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Our findings suggest that healthy elderly women with higher values of PhA have a better muscle quality and functionality, regardless of age and body composition.<\/jats:p>\n <\/jats:sec>","DOI":"10.1519\/jpt.0000000000000161","type":"journal-article","created":{"date-parts":[[2017,11,29]],"date-time":"2017-11-29T21:32:49Z","timestamp":1511991169000},"page":"281-286","source":"Crossref","is-referenced-by-count":68,"title":["Phase Angle Is Moderately Associated With Muscle Quality and Functional Capacity, Independent of Age and Body Composition in Older Women"],"prefix":"10.1519","volume":"42","author":[{"given":"Crisieli M.","family":"Tomeleri","sequence":"first","affiliation":[{"name":"Metabolism, Nutrition, and Exercise Laboratory, Londrina State University, Londrina, Brazil."}]},{"given":"Edilaine F.","family":"Cavalcante","sequence":"additional","affiliation":[{"name":"Metabolism, Nutrition, and Exercise Laboratory, Londrina State University, Londrina, Brazil."}]},{"given":"Melissa","family":"Antunes","sequence":"additional","affiliation":[{"name":"Metabolism, Nutrition, and Exercise Laboratory, Londrina State University, Londrina, Brazil."}]},{"given":"Hellen C.
