The purpose of this systematic review was to analyze and consolidate the available scientific evidence from the main databases on the use of infrared thermography in the assessment of fatigue, injury risk factors, and recovery in soccer players.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The literature search was conducted following the PRISMA guidelines and the PICOS model until June 30, 2025, in the main scientific databases (ScienceDirect, EMBASE, Web of Science (WOS), Cochrane Library, SciELO, MEDLINE\/PubMed, SPORTDiscus, and Scopus). The risk of bias and methodological quality were assessed using the Cochrane Handbook guidelines and the PEDro scale.\u201d<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The initial literature search yielded a total of 510 records. After applying the inclusion and exclusion criteria, the final sample consisted of 20 studies, which were of high methodological quality. The results showed the effects of infrared thermography in assessing fatigue, identifying injury risk factors, and monitoring recovery processes in soccer players. The studies also systematically reported the characterization of the population, the assessment methods used, the variables analyzed, the methodological design, the main results, and the effects of the intervention.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Infrared thermography shows promise as a valid, reliable, and non-invasive tool for assessing skin temperature, reflecting temperature changes in response to physiological processes. It allows for the analysis of structural or metabolic fatigue and thermal asymmetries. Therefore, thermography could be used to design individualized recovery protocols.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fphys.2026.1835464","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T04:34:52Z","timestamp":1781757292000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Infrared thermography to assess fatigue, injury risk factors and recovery in soccer: a systematic review of original studies"],"prefix":"10.3389","volume":"17","author":[{"given":"Yehinson","family":"Barajas Ram\u00f3n","sequence":"first","affiliation":[{"name":"Facultad de Ciencias de la Salud, Universidad Europea del Atl\u00e1ntico","place":["Santander, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julio","family":"Calleja-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Physical Education and Sport, Faculty of Education and Sport, University of the Basque Country (UPV\/EHU)","place":["Vitoria, Spain"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9","family":"Luaces-Carre\u00f1o","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud, Universidad Europea del Atl\u00e1ntico","place":["Santander, Spain"]},{"name":"Universidad de La Romana","place":["La Romana, Dominican Republic"]},{"name":"Fundaci\u00f3n Universitaria Internacional de Colombia","place":["Bogot\u00e1, Colombia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c1lvaro","family":"Velarde-Sotres","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud, Universidad Europea del Atl\u00e1ntico","place":["Santander, Spain"]},{"name":"Departamento de Salud, Universidad Internacional Iberoamericana","place":["Campeche, Mexico"]},{"name":"Faculdade de Ci\u00eancias de Sa\u00fade, Universidade Internacional do Cuanza","place":["Cuito, Bi\u00e9, Angola"]},{"name":"Departamento de Salud, Universidad Internacional Iberoamericana","place":["Arecibo, PR, United States"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"19","DOI":"10.5114\/biolsport.2021.103570","article-title":"Utilisation of performance markers to establish the effectiveness of cold-water immersion as a recovery modality in elite football","volume":"39","author":"Alexander","year":"2022","journal-title":"Biol.
