However, evidence regarding its impact on combat sports particularly in female athletes remains limited. The aim of this study was to evaluate the acute effects of beetroot juice supplementation on simulated taekwondo combat performance and neuromuscular function in elite female taekwondo athletes. Seven elite female Olympic taekwondo athletes (age: 20.3 \u00b1 3.7 years), participated in a randomized, double-blind, placebo-controlled study consisting of two experimental trials). Each trial involved the consumption of either 140 mL of beetroot juice (which contains 12.8 mmol NO\u2083\u207b) or 140 mL of a placebo (with 0.08 mmol NO\u2083\u207b) followed by a simulated taekwondo combat session and assessments of neuro-muscular function (i.e., vertical jump and visual cognitive performance). In addition, metabolic (i.e., blood lactate), and perceptual responses (i.e., rate of perceived exertion) were measured before, after, and 3 minutes post-combat. No significant differences during the simulated taekwondo combat (e.g., attack time; p = 0.531\u20130.989; \u03b7p\u00b2 = 0.01\u20130.05), neuromuscular function battery (p = 0.302-0.700; \u03b7p\u00b2 = 0.02-0.04), blood lactate concentrations (p = 0.705; \u03b7p\u00b2 = 0.13), or rate of perceived exertion values (RPE) (p = 0.717; \u03b7p\u00b2 = 0.12) were obtained between beetroot juice and placebo conditions. Acute ingestion of beetroot juice (140 mL) did not enhance simulated combat performance or neuromuscular function in female Olympic taekwondo athletes.<\/jats:p>","DOI":"10.4081\/ejtm.2026.15641","type":"journal-article","created":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T09:55:05Z","timestamp":1791453305000},"source":"Crossref","is-referenced-by-count":0,"title":["Ergogenic effects of beetroot juice supplementation on neuromuscular function and simulated combat demands in elite female taekwondo athletes"],"prefix":"10.4081","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2032-905X","authenticated-orcid":true,"given":"Rom\u00e1n","family":"Illescas-Quiroga","sequence":"first","affiliation":[{"name":"Department of Biomedical Sciences, Physical and Sports Education Area, Faculty of Medicine and Health Sciences, University of Alcal\u00e1, Alcal\u00e1 de Henares, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0721-0150","authenticated-orcid":true,"given":"\u00c1lvaro","family":"L\u00f3pez-Samanes","sequence":"additional","affiliation":[{"name":"GICAF Research Group, Education, Research Methods, and Evaluation Department, Faculty of Human and Social Sciences, Universidad Pontificia Comillas, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luc\u00eda","family":"S\u00e1nchez-Llanos","sequence":"additional","affiliation":[{"name":"Hospital Universitario La Paz, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jes\u00fas","family":"Ramal","sequence":"additional","affiliation":[{"name":"Hankuk International School of Taekwondo, San Sebastian de los Reyes, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8539-4306","authenticated-orcid":true,"given":"Alireza","family":"Naderi","sequence":"additional","affiliation":[{"name":"Department of Sport Physiology, Faculty of Human Sciences, Borujerd Branch, Islamic Azad University, Borujerd"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ra\u00fal","family":"Dom\u00ednguez","sequence":"additional","affiliation":[{"name":"Studies Research Group in Neuromuscular Responses (GEPREN), University of Lavras, Lavras, Brazil; Grupo de Optimizaci\u00f3n del Entrenamiento Deportivo (GOPED), Department of Human Motricity and High Performance, University of Seville, Seville"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7575-0100","authenticated-orcid":true,"given":"Juan Jose","family":"Ramos-\u00c1lvarez","sequence":"additional","affiliation":[{"name":"Department of Radiology and Rehabilitation, School of Sport Medicine, Faculty of Medicine, Complutense University Madrid, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0427-6322","authenticated-orcid":true,"given":"Juan Jose","family":"Montoya-Mi\u00f1ano","sequence":"additional","affiliation":[{"name":"Department of Radiology and Rehabilitation, School of Sport Medicine, Faculty of Medicine, Complutense University Madrid, Madrid"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2549","published-online":{"date-parts":[[2026,10,8]]},"reference":[{"key":"254958","doi-asserted-by":"crossref","unstructured":"1.
