Fourteen recreationally active males were assigned in a randomized, double-blind, crossover design to supplement for 4 days in two conditions: (1) NO3\u2212-depleted beetroot juice (PL; 0.10 mmol NO3\u2212 per day) and (2) BR (11.8 mmol NO3\u2212 per day). On days 1 and 4 of the supplementation periods, participants completed 2 sets of 2 \u00d7 70%1RM interspersed by 2 min of recovery, followed by one set of repetitions-to-failure (RTF) at 60%1RM for the determination of muscular power, velocity, and endurance. Quadriceps and pectoralis major tissue saturation index (TSI) were measured throughout exercise. Plasma [NO3\u2212] and nitrite ([NO2\u2212]) were higher after 1 and 4 days of supplementation with BR compared to PL (p &lt; 0.05). Quadriceps and pectoralis major TSI were not different between conditions (p &gt; 0.05). The number of RTF in bench press was 5% greater after acute BR ingestion compared to PL (PL: 23 \u00b1 4 vs. BR: 24 \u00b1 5, p &lt; 0.05). There were no differences between BR and PL for RTF for back squat or power and velocity for back squat or bench press (p &gt; 0.05). These data improve understanding on the ergogenic potential of BR supplementation during resistance exercise.<\/jats:p>","DOI":"10.3390\/nu14183703","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T07:05:56Z","timestamp":1662620756000},"page":"3703","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Effects of Dietary Nitrate Supplementation on Performance and Muscle Oxygenation during Resistance Exercise in Men"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8669-168X","authenticated-orcid":false,"given":"Rachel","family":"Tan","sequence":"first","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0876-4972","authenticated-orcid":false,"given":"Adam","family":"Pennell","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7262-5200","authenticated-orcid":false,"given":"Katherine M.","family":"Price","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2542-3168","authenticated-orcid":false,"given":"Sean T.","family":"Karl","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noelle G.","family":"Seekamp-Hicks","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keonabelle K.","family":"Paniagua","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grant D.","family":"Weiderman","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna P.","family":"Powell","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luka K.","family":"Sharabidze","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabella G.","family":"Lincoln","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin M.","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeleine F.","family":"Espinoza","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maya A.","family":"Hammer","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Pepperdine University, Malibu, CA 90263, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richie P.","family":"Goulding","sequence":"additional","affiliation":[{"name":"Laboratory for Myology, Faculty of Behavioural and Movement Sciences, Amsterdam Movement Sciences, Vrije Universiteit Amsterdam, 1081 HZ Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen J.","family":"Bailey","sequence":"additional","affiliation":[{"name":"School of Sport, Exercise and Health Sciences, Loughborough University, Loughborough LE11 3TU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1152\/physrev.2001.81.1.209","article-title":"Physiology of Nitric Oxide in Skeletal Muscle","volume":"81","author":"Stamler","year":"2001","journal-title":"Physiol.
