This study aimed to describe the changes in sprint force\u2013velocity (Fv) profile after a period of 25\u00a0weeks of regular training in international football players with CP. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> The sprint Fv profile and other physical performance variables (ie,\u00a0linear sprint, vertical jump, change of direction, and intermittent endurance) of 14 international players from the Spanish national team were assessed during 2 consecutive training camps. Pretesting and posttesting sessions were carried out 1\u00a0week before and after the 25-week intervention period. The intervention consisted of 2 strength sessions per week added to the usual football training. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> The repeated-measures analysis of variance showed changes in players\u2019 physical performance (linear sprint: <jats:italic>F<\/jats:italic>\u2009=\u200918.05, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01; change of direction: <jats:italic>F<\/jats:italic>\u2009=\u200916.71, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01; and endurance: <jats:italic>F<\/jats:italic>\u2009=\u200931.45, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01) and in some variables of the sprint Fv profile (maximal horizontal force, maximal power, slope, maximal ratio of force, and decrease of ratio of force; <jats:italic>F<\/jats:italic>\u2009=\u200914.28\u201337.81; <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.01), whereas players\u2019 maximal velocity (theoretical and actual) did not change (<jats:italic>F<\/jats:italic>\u2009=\u20090.13 and 0.01; <jats:italic>P<\/jats:italic>\u2009=\u2009.72 and .98, respectively). <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> This study showed that the implementation of 2 strength-training sessions per week, for 25\u00a0weeks, is effective to improve CP football players\u2019 physical performance. The main finding of this study is the improvement of force application in the acceleration phase (sprint Fv profile), which is the main attribute in many physical performance tests and is the main limitation of the CP population.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0317","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T13:21:30Z","timestamp":1678972890000},"page":"495-502","source":"Crossref","is-referenced-by-count":4,"title":["Changes in Sprint Force\u2013Velocity Profile in International Para Footballers"],"prefix":"10.1123","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6810-0911","authenticated-orcid":true,"given":"Iv\u00e1n","family":"Pe\u00f1a-Gonz\u00e1lez","sequence":"first","affiliation":[{"name":"Department of Sport Sciences, Sport Research Center, Miguel Hern\u00e1ndez University, Elche, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2689-4244","authenticated-orcid":true,"given":"Alejandro","family":"Javaloyes","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, Sport Research Center, Miguel Hern\u00e1ndez University, Elche, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1917-6634","authenticated-orcid":true,"given":"Jose Manuel","family":"Sarabia","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, Sport Research Center, Miguel Hern\u00e1ndez University, Elche, Spain"},{"name":"Miguel Hern\u00e1ndez University of Elche, Alicante Institute for Health and Biomedical Research (ISABIAL), Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2291-5899","authenticated-orcid":true,"given":"Manuel","family":"Moya-Ram\u00f3n","sequence":"additional","affiliation":[{"name":"Department of Sport Sciences, Sport Research Center, Miguel Hern\u00e1ndez University, Elche, Spain"},{"name":"Miguel Hern\u00e1ndez University of Elche, Alicante Institute for Health and Biomedical Research (ISABIAL), Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"key":"r1","series-title":"Classification Rules and Regulations","first-page":"1","year":"2018","unstructured":"IFCPF.
