Thus, the aim of this trial was to investigate Lactobacillus plantarum\u2019s effects on sports performance, intestinal damage, and oxidative stress biomarkers. Methods: Twenty-two physically active participants, nine females and thirteen males (age: 32.8 \u00b1 5.2 years; height: 1.73 \u00b1 0.1 m (meters); body mass: 72.2 \u00b1 10.3 kg (kilograms) volunteered in this randomized, double-blind, placebo-controlled, parallel study. The participants performed a strenuous exercise session, and immediately after, their perceived exertion was assessed and blood samples were drawn to assess intestinal damage (IFABP: intestinal fatty acid binding protein) and oxidative stress (PC: protein carbonyls; TAC: total antioxidant capacity; total proteins; GSSG: glutathione disulfide; GSH: reduced glutathione and catalase). Twenty-four hours later, the participants ranked their recovery status and completed various sports performance tests: CMJ (countermovement jump), RAST (running-based anaerobic sprint), and YOYO IR1 (YOYO intermittent recovery test level 1). This was followed by a four-week supplementation period, in which the participants ingested one probiotic capsule per day containing 10 billion CFU (colony forming units) of Lactobacillus plantarum or a placebo capsule (dextrose). Results: The paired samples t-test revealed a significantly better result in the YOYO IR1 test in the probiotic group, while a significant reduction was observed in the TAC levels in the placebo group. Conclusions: The results suggest that Lactobacillus plantarum supplementation could increase YOYO IR1 sports performance test scores and may mitigate TAC value reduction.<\/jats:p>","DOI":"10.3390\/jfmk10020131","type":"journal-article","created":{"date-parts":[[2025,4,15]],"date-time":"2025-04-15T08:11:39Z","timestamp":1744704699000},"page":"131","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Lactobacillus plantarum Supplementation on Sport Performance, Biomarkers of Intestinal Damage, and Oxidative Stress in Recreational Athletes"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7971-3182","authenticated-orcid":false,"given":"Asier","family":"Santiba\u00f1ez-Gutierrez","sequence":"first","affiliation":[{"name":"Department of Physical Education and Sports, Faculty of Education and Sport, University of the Basque Country (UPV\/EHU), 01007 Vitoria, Spain"},{"name":"Applied Bioenergetics Lab, Faculty of Sport and Physical Education, University of Novi Sad, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2900-1712","authenticated-orcid":false,"given":"Julen","family":"Fern\u00e1ndez-Landa","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Faculty of Education and Sport, University of the Basque Country (UPV\/EHU), 01007 Vitoria, Spain"},{"name":"Applied Bioenergetics Lab, Faculty of Sport and Physical Education, University of Novi Sad, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9637-1209","authenticated-orcid":false,"given":"Natalia","family":"Busto","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Burgos, 09001 Burgos, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nikola","family":"Todorovic","sequence":"additional","affiliation":[{"name":"Applied Bioenergetics Lab, Faculty of Sport and Physical Education, University of Novi Sad, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2575-7168","authenticated-orcid":false,"given":"Julio","family":"Calleja-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sports, Faculty of Education and Sport, University of the Basque Country (UPV\/EHU), 01007 Vitoria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6554-4602","authenticated-orcid":false,"given":"Juan","family":"Mielgo-Ayuso","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Faculty of Health Sciences, University of Burgos, 09001 Burgos, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"188","DOI":"10.1123\/ijsnem.2017-0340","article-title":"Dietary supplements for health, adaptation, and recovery in athletes","volume":"28","author":"Rawson","year":"2018","journal-title":"Int.
