Eighteen healthy, untrained young men underwent an 8-week whole-body resistance training program, comprising three sessions per week. Subjects were randomized into three groups that after each training session consumed: (1) 30 g whey protein concentrate containing 23 g protein (WG), (2) 50 g chia flour containing 20 g protein (CG), or (3) a placebo not containing protein (PG). Strength tests (lower- and upper-limb one repetition maximum (1 RM) tests) and body composition analyses (dual-energy X-ray absorptiometry; DXA) were performed before (PRE) and after (POST) the intervention. Resistance training increased FFM and the 1 RM for each of the strength tests similarly in the three groups. FFM increased by 2.3% in WG (p = 0.04), by 3.6% in CG (p = 0.004), and by 3.0% in PG (p = 0.002)., and 1 RM increased in the different strength tests in the three groups (p &lt; 0.05) with no difference between PG, CG, and WG. In conclusion, neither chia flour nor whey protein supplementation elicited an enhanced effect on FFM and strength gains after an 8-week resistance training program in healthy, untrained young men consuming a habitual high protein mixed diet (&gt;1.2 g\/kg\/day).<\/jats:p>","DOI":"10.3390\/nu15061365","type":"journal-article","created":{"date-parts":[[2023,3,13]],"date-time":"2023-03-13T02:31:55Z","timestamp":1678674715000},"page":"1365","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Neither Chia Flour nor Whey Protein Supplementation Further Improves Body Composition or Strength Gains after a Resistance Training Program in Young Subjects with a Habitual High Daily Protein Intake"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9643-1037","authenticated-orcid":false,"given":"Hermann","family":"Zbinden-Foncea","sequence":"first","affiliation":[{"name":"Exercise Physiology and Metabolism Laboratory, School of Kinesiology, Faculty of Medicine, Universidad Finis Terrae, Santiago 7500000, Chile"},{"name":"Centro de Salud Deportiva, Cl\u00ednica Santa Mar\u00eda, Santiago 7571894, Chile"},{"name":"Institute of Neuroscience, UCLouvain, 1348 Louvain-la-Neuve, Belgium"},{"name":"Faculty of Health Science, Universidad Francisco de Vitoria, 28223 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Ramos-Navarro","sequence":"additional","affiliation":[{"name":"Exercise Physiology and Metabolism Laboratory, School of Kinesiology, Faculty of Medicine, Universidad Finis Terrae, Santiago 7500000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3019-4462","authenticated-orcid":false,"given":"Victoria","family":"Hevia-Larra\u00edn","sequence":"additional","affiliation":[{"name":"Exercise Physiology and Metabolism Laboratory, School of Kinesiology, Faculty of Medicine, Universidad Finis Terrae, Santiago 7500000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauricio","family":"Castro-Sepulveda","sequence":"additional","affiliation":[{"name":"Exercise Physiology and Metabolism Laboratory, School of Kinesiology, Faculty of Medicine, Universidad Finis Terrae, Santiago 7500000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Jos\u00e9","family":"Sa\u00fal","sequence":"additional","affiliation":[{"name":"Exercise Physiology and Metabolism Laboratory, School of Kinesiology, Faculty of Medicine, Universidad Finis Terrae, Santiago 7500000, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cesar","family":"Kalazich","sequence":"additional","affiliation":[{"name":"Cl\u00ednica MEDS, Santiago 7571894, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3393-5278","authenticated-orcid":false,"given":"Louise","family":"Deldicque","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience, UCLouvain, 1348 Louvain-la-Neuve, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,11]]},"reference":[{"key":"ref_1","first-page":"E122","article-title":"An abundant supply of amino acids enhances the metabolic effect of exercise on muscle protein","volume":"273","author":"Biolo","year":"1997","journal-title":"Am.
