Fifty-two male academy outfield players were randomized to 6\u00a0weeks of MSPE or an education-based active attention control. Assessments were completed pre, post, and 3-month follow-up; 90-min matches were framed as selection-relevant trials and video-coded by blinded raters. Mixed analyses of variance showed a significant Group\u2009\u00d7\u2009Time interaction for under pressure performance (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u2009.001): MSPE improved at posttest and remained superior at follow-up. Relative to education-based active attention control, flow increased and somatic anxiety decreased, with smaller effects for cognitive anxiety and aggression; aggression was not maintained. Findings were robust to sensitivity analyses using linear mixed-effects model. Exploratory mediation analyses provided no clear evidence that changes in psychological variables explained performance gains. Overall, MSPE offers a practical, field-ready approach for supporting under pressure performance and related psychological outcomes in youth soccer.\n                  <\/jats:p>","DOI":"10.1123\/jsep.2026-0002","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T16:45:57Z","timestamp":1777999557000},"page":"229-240","source":"Crossref","is-referenced-by-count":0,"title":["Mindful Sport Performance Enhancement in Youth Soccer: A Randomized Active-Control Trial of Objective Performance Under Pressure and Psychological Outcomes"],"prefix":"10.1123","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2086-6632","authenticated-orcid":true,"given":"Alireza","family":"Farsi","sequence":"first","affiliation":[{"name":"Faculty of Sport Sciences and Health, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javad","family":"Shakerd","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences and Health, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1956-4108","authenticated-orcid":true,"given":"Ebrahim","family":"Moteshareie","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences and Health, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9127-1176","authenticated-orcid":true,"given":"Erfan","family":"Sedighi","sequence":"additional","affiliation":[{"name":"Faculty of Sport Sciences and Health, Shahid Beheshti University, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"3","key":"r1","series-title":"Australasian Psychiatry,","doi-asserted-by":"publisher","first-page":"291","DOI":"10.1177\/1039856219828119","article-title":"Applying mindfulness training to enhance the mental toughness and emotional intelligence of amateur basketball players","volume":"27","author":"Ajilchi, B.","year":"2019","unstructured":"Ajilchi, B., Amini, H.R., Ardakani, Z.P., Zadeh, M.M., & Kisely, S.
