Notably, hamstring injuries in football players often occur during sprinting activities and fatigue-inducing conditions. Therefore, the aim of this study was to examine the impact of repeated-sprint training (RST) on repeated-sprint ability variables and sprint kinematics. Fourteen semiprofessional men\u2019s soccer players performed 8\u00a0weeks of RST, consisting of 1 to 2 sets of 5 to 8\u2009\u00d7\u200930\u00a0m repeated sprints separated by 20 to 30\u00a0seconds of recovery. Sprint performance was computed from running speed data, and a high-frequency camera (240\u00a0Hz) was used to study kinematic data. Paired samples <jats:italic>t<\/jats:italic> test and repeated-measures analysis of variance were conducted for each performance and kinematic variable, respectively. After the RST period, moderate to large improvements were observed for 0 to 20\u00a0m time, 0 to 30\u00a0m time, and 20 to 30\u00a0m time. All the repeated-sprint ability-related variables were significantly improved (<jats:italic>P<\/jats:italic>\u2009&lt;\u2009.05). In addition, during fatigue conditions, a decrease in trunk flexion and kick-back mechanism and a reduced overstriding pattern was found after RST. The findings of this study suggest that incorporating RST may lead to improved sprint performance and promote a \u201csafer\u201d sprint pattern, particularly during periods of fatigue.<\/jats:p>","DOI":"10.1123\/jab.2024-0026","type":"journal-article","created":{"date-parts":[[2024,11,15]],"date-time":"2024-11-15T17:57:18Z","timestamp":1731693438000},"page":"18-26","source":"Crossref","is-referenced-by-count":3,"title":["Enhancing Sprint Performance and Biomechanics in Semiprofessional Football Players Through Repeated-Sprint Training"],"prefix":"10.1123","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5391-5023","authenticated-orcid":true,"given":"Valentin","family":"Romero","sequence":"first","affiliation":[{"name":"Centre for Sport Studies, Rey Juan Carlos University, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adri\u00e1n","family":"Casta\u00f1o-Zambudio","sequence":"additional","affiliation":[{"name":"Centre for Sport Studies, Rey Juan Carlos University, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manuel Alejandro","family":"Ortega-Becerra","sequence":"additional","affiliation":[{"name":"Physical Performance and Sports Research Center, Faculty of Sports Science, Pablo de Olavide University, Sevilla, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9927-8472","authenticated-orcid":true,"given":"Juan Antonio","family":"V\u00e1zquez-Diz","sequence":"additional","affiliation":[{"name":"Departamento de Educaci\u00f3n F\u00edsica y Deporte, Escuela Universitaria de Osuna, Sevilla, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juan Jes\u00fas","family":"Adalid-Leiva","sequence":"additional","affiliation":[{"name":"Antequera Club de F\u00fatbol, Antequera, M\u00e1laga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8156-243X","authenticated-orcid":true,"given":"Pedro","family":"Jim\u00e9nez-Reyes","sequence":"additional","affiliation":[{"name":"Centre for Sport Studies, Rey Juan Carlos University, Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"11","key":"r1","series-title":"Int J Sports Med","doi-asserted-by":"publisher","first-page":"899","DOI":"10.1055\/s-2008-1038491","article-title":"Validity of a repeated-sprint test for football","volume":"29","author":"Impellizzeri FM","year":"2008","unstructured":"Impellizzeri FM, Rampinini E, Castagna C, et\u00a0al.
