A total of 737 professional women and men soccer players were monitored during 5\u201310 official matches. Data were collected using 18-Hz GPS devices to derive AS profiles and directly measure acceleration and speed output. Across all playing levels, professional men soccer players demonstrated significantly (p &lt; 0.01) higher values than female players for A0 (d = 1.14\u20131.87), S0 (d = 3.88\u20134.82), MaxAcc (d = 0.57\u20131.22), and MaxSpeed (d = 2.46\u20132.81). Likewise, players of higher sports levels showed superior output than their lower counterparts (First Men\u2019s Division &gt; Second Men\u2019s Division &gt; Under 20 Men\u2019s Division; p &lt; 0.05). Position-specific analysis revealed that midfielders had significantly (p &lt; 0.05) lower MaxSpeed values than other positions such as full-backs (d = 0.63\u20131.17), wide midfielders (d = 0.82), and forwards (d = 0.67\u20131.06) in both the First and Second Divisions. Conversely, wide midfielders in the Under 20 Men\u2019s Division exhibited significantly (p &lt; 0.05) higher A0 values than central defenders (d = 0.78). These findings highlight the importance of conducting sex- and position-specific analyses of the AS profile to effectively monitor acceleration and speed capacities across different sports levels in professional soccer.<\/jats:p>","DOI":"10.5114\/jhk\/220252","type":"journal-article","created":{"date-parts":[[2026,8,5]],"date-time":"2026-08-05T08:19:21Z","timestamp":1785917961000},"page":"149-160","source":"Crossref","is-referenced-by-count":0,"title":["The Acceleration-Speed Profile in Professional Soccer Players: \nA Comparative Study According to Sex, the Sports Level \nand the Playing Position"],"prefix":"10.5114","volume":"103","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7813-3928","authenticated-orcid":false,"given":"Andres","family":"Lopez-Sagarra","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1336-5979","authenticated-orcid":false,"given":"Manuel Antonio","family":"Rodriguez-Perez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexis","family":"Padr\u00f3n-Cabo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6590-6773","authenticated-orcid":false,"given":"Andres","family":"Baena-Raya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3061","published-online":{"date-parts":[[2026,7,20]]},"reference":[{"key":"ref-1937201","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0000000000004637"},{"key":"ref-1937202","doi-asserted-by":"publisher","DOI":"10.1038\/S41598-022-23790-W"},{"key":"ref-1937203","doi-asserted-by":"publisher","DOI":"10.1055\/a-1293-8471"},{"key":"ref-1937204","doi-asserted-by":"publisher","DOI":"10.1080\/17461391.2020.1856934"},{"key":"ref-1937205","doi-asserted-by":"publisher","DOI":"10.1080\/02640410500482529"},{"key":"ref-1937206","doi-asserted-by":"publisher","DOI":"10.1080\/17461391.2018.1427796"},{"key":"ref-1937207","doi-asserted-by":"publisher","DOI":"10.18637\/JSS.V067.I01"},{"key":"ref-1937208","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2024.2307768"},{"key":"ref-1937209","doi-asserted-by":"publisher","DOI":"10.5114\/jhk\/204820"},{"key":"ref-1937210","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0277326"},{"key":"ref-1937211","doi-asserted-by":"publisher","DOI":"10.1007\/s11332-025-01352-7"},{"key":"ref-1937212","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2024.2305005"},{"key":"ref-1937213","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2023.111602"},{"key":"ref-1937214","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.2021-0339"},{"key":"ref-1937215","doi-asserted-by":"publisher","DOI":"10.1016\/J.JBIOMECH.2023.111724"},{"key":"ref-1937216","doi-asserted-by":"publisher","DOI":"10.3390\/ijerph17238815"},{"key":"ref-1937217","doi-asserted-by":"crossref","unstructured":"Dalen, T., Ingebrigtsen, J., Ettema, G., Hjelde, G.
