In a double-blind matched-pairs design, 16 resistance-trained participants, routinely performing hypertrophy training, were randomly assigned to a BCAA (n = 8) or placebo (n = 8) group. The BCAAs were administered at a dosage of 0.087 g\/kg body mass, with a 2:1:1 ratio of leucine, isoleucine, and valine. The participants performed 6 sets of 10 full-squats at 70% 1-repetition maximum to induce muscle damage. All participants were diet-controlled across the study. Creatine kinase, peak isometric knee-extensor force, perceived muscle soreness, and countermovement jump (CMJ) height were measured immediately before (baseline) and at 1 h, 24 h, and 48 h postexercise. There were large to very large time effects for all measurements between baseline and 24\u201348 h. Between-group comparisons, expressed as a percentage of baseline, revealed differences in isometric strength at 24-h (placebo \u223c87% vs. BCAA \u223c92%; moderate, likely), CMJ at 24 h (placebo \u223c93% vs. BCAA \u223c96%; small, likely), and muscle soreness at both 24 h (placebo \u223c685% vs. BCAA \u223c531%; small, likely) and 48 h (placebo \u223c468% vs. BCAA \u223c350%; small, likely). Acute supplementation of BCAAs (0.087 g\/kg) increased the rate of recovery in isometric strength, CMJ height, and perceived muscle soreness compared with placebo after a hypertrophy-based training session among diet-controlled, resistance-trained athletes. These findings question the need for longer BCAA loading phases and highlight the importance of dietary control in studies of this type. <\/jats:p>","DOI":"10.1139\/apnm-2016-0569","type":"journal-article","created":{"date-parts":[[2017,1,27]],"date-time":"2017-01-27T22:34:41Z","timestamp":1485556481000},"page":"630-636","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["The effects of acute branched-chain amino acid supplementation on recovery from a single bout of hypertrophy exercise in resistance-trained athletes"],"prefix":"10.1139","volume":"42","author":[{"given":"Mark","family":"Waldron","sequence":"first","affiliation":[{"name":"School of Sport, Health and Applied Science, St Mary\u2019s University, Waldegrave Road, Twickenham, London TW1 4SX, UK."},{"name":"School of Science and Technology, University of New England, NSW 2350, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kieran","family":"Whelan","sequence":"additional","affiliation":[{"name":"School of Sport, Health and Applied Science, St Mary\u2019s University, Waldegrave Road, Twickenham, London TW1 4SX, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Owen","family":"Jeffries","sequence":"additional","affiliation":[{"name":"School of Sport, Health and Applied Science, St Mary\u2019s University, Waldegrave Road, Twickenham, London TW1 4SX, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dean","family":"Burt","sequence":"additional","affiliation":[{"name":"Sport and Exercise Science, Brindley Building, Staffordshire University, Leek Road, Stoke-on-Trent, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louis","family":"Howe","sequence":"additional","affiliation":[{"name":"School of Sport, Health and Applied Science, St Mary\u2019s University, Waldegrave Road, Twickenham, London TW1 4SX, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen David","family":"Patterson","sequence":"additional","affiliation":[{"name":"School of Sport, Health and Applied Science, St Mary\u2019s University, Waldegrave Road, Twickenham, London TW1 4SX, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0b013e3181915670"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejcn.1601940"},{"key":"refg3\/ref3","doi-asserted-by":"publisher","DOI":"10.2165\/00007256-200636090-00005"},{"key":"refg4\/ref4","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.1.1.50"},{"key":"refg5\/ref5","doi-asserted-by":"crossref","first-page":"269s","DOI":"10.1093\/jn\/136.1.269S","volume":"136","author":"Blomstrand E.","year":"2006","journal-title":"J.
