Sixteen healthy young adults were assigned in a randomized crossover design to receive beetroot juice (BRJ) or an NO3\u2212-depleted control beverage (prune juice: CON). Two hours after consuming the allocated beverage, participants rested in the supine position. Following the baseline period of 4 min, static handgrip exercise of the left hand was performed at 30% of the maximal voluntary contraction for 2 min. Mean arterial pressure (MAP) and heart rate (HR) were measured. Changes in venous volume in the right forearm and right calf were also measured using venous occlusion plethysmography while cuffs on the upper arm and thigh were inflated constantly to 30\u201340 mmHg. The plasma NO3\u2212 concentration was elevated with BRJ intake (p &lt; 0.05). Exercise increased MAP and HR and decreased venous volume in the forearm and calf, but there were no differences between CON and BRJ. Thus, these findings suggest that acute BRJ intake does not alter the sympathetic venoconstriction in the non-exercising limbs and MAP response to exercise in healthy young adults, despite the enhanced activity of nitric oxide.<\/jats:p>","DOI":"10.3390\/nu14214464","type":"journal-article","created":{"date-parts":[[2022,10,24]],"date-time":"2022-10-24T08:19:06Z","timestamp":1666599546000},"page":"4464","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Effect of Acute Dietary Nitrate Supplementation on the Venous Vascular Response to Static Exercise in Healthy Young Adults"],"prefix":"10.3390","volume":"14","author":[{"given":"Anna","family":"Oue","sequence":"first","affiliation":[{"name":"Faculty of Food and Nutritional Sciences, Toyo University, Gunma 374-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiro","family":"Iimura","sequence":"additional","affiliation":[{"name":"Graduate School of Food and Nutritional Sciences, Toyo University, Gunma 374-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0391-580X","authenticated-orcid":false,"given":"Akiho","family":"Shinagawa","sequence":"additional","affiliation":[{"name":"Graduate School of Food and Nutritional Sciences, Toyo University, Gunma 374-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichi","family":"Miyakoshi","sequence":"additional","affiliation":[{"name":"Faculty of Food and Nutritional Sciences, Toyo University, Gunma 374-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masako","family":"Ota","sequence":"additional","affiliation":[{"name":"Faculty of Food and Nutritional Sciences, Toyo University, Gunma 374-0193, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2066","DOI":"10.1017\/S0007114512000190","article-title":"Blood pressure-lowering effects of beetroot juice and novel beetroot-enriched bread products in normotensive male subjects","volume":"108","author":"Hobbs","year":"2012","journal-title":"Br.
