This study compared sprint mechanical outputs derived from a Kinexon local positioning system (LPS), radar, and laser during maximal indoor basketball sprints and examined their inter-system agreement and inter-trial reliability. Twenty-two elite youth basketball players performed maximal 28 m linear sprints recorded simultaneously using the three technologies. Sprint kinematics were modeled using a mono-exponential approach applied to the native signals provided by each system to derive theoretical maximal velocity (S0), theoretical maximal acceleration (A0), and acceleration time constant (Tau). Inter-system agreement was assessed using mean bias and 95% limits of agreement, while inter-trial reliability was evaluated using coefficients of variation (CV), change in the mean, and standard error of measurement. Radar and laser showed close agreement for S0 (bias = \u22120.07 \u00b1 0.17 m\u00b7s\u22121; relative error = 0.89%), whereas LPS systematically overestimated S0, with relative systematic errors of 5.26\u20136.49%. Acceleration-related parameters exhibited larger inter-system discrepancies, with relative errors up to 3.92% for A0 and 10.55% for Tau. Inter-trial reliability was high across all systems (CV &lt; 1.5% for S0 and 3.7\u20134.7% for A0 and Tau). These findings indicate that sprint mechanical outputs should not be used interchangeably across technologies, particularly for acceleration-related variables, although all systems remain suitable for within-system longitudinal monitoring in applied basketball settings.<\/jats:p>","DOI":"10.3390\/s26154845","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T11:50:21Z","timestamp":1785757821000},"page":"4845","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessing Sprint Mechanical Outputs Derived from LPS, Radar and Laser Technologies in Basketball"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-9648-4127","authenticated-orcid":false,"given":"Yannis","family":"Irid","sequence":"first","affiliation":[{"name":"IRMES\u2014UMR 7329, Institut de Recherche M\u00e9dicale et d\u2019\u00c9pid\u00e9miologie du Sport, Universit\u00e9 de Paris Cit\u00e9, 75012 Paris, France"},{"name":"Institut National du Sport, de l\u2019Expertise et de la Performance (INSEP), 75012 Paris, France"},{"name":"F\u00e9d\u00e9ration Fran\u00e7aise de Basketball (FFBB), 75013 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00c9ric","family":"Fenaux","sequence":"additional","affiliation":[{"name":"Ef-E-Sciences, Independent Scientific Consultancy, 75009 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7362-5402","authenticated-orcid":false,"given":"Rom\u00e9o","family":"Legoupil","sequence":"additional","affiliation":[{"name":"IRMES\u2014UMR 7329, Institut de Recherche M\u00e9dicale et d\u2019\u00c9pid\u00e9miologie du Sport, Universit\u00e9 de Paris Cit\u00e9, 75012 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathis","family":"Tachdjian","sequence":"additional","affiliation":[{"name":"Institut National du Sport, de l\u2019Expertise et de la Performance (INSEP), 75012 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8054-546X","authenticated-orcid":false,"given":"C\u00e9dric","family":"Leduc","sequence":"additional","affiliation":[{"name":"IRMES\u2014UMR 7329, Institut de Recherche M\u00e9dicale et d\u2019\u00c9pid\u00e9miologie du Sport, Universit\u00e9 de Paris Cit\u00e9, 75012 Paris, France"},{"name":"Center for Human Performance, Carnegie School of Sport, Leeds Beckett University, Leeds LS1 3HE, UK"},{"name":"F\u00e9d\u00e9ration Fran\u00e7aise de Tennis (FFT), 75016 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Fran\u00e7ois","family":"Toussaint","sequence":"additional","affiliation":[{"name":"IRMES\u2014UMR 7329, Institut de Recherche M\u00e9dicale et d\u2019\u00c9pid\u00e9miologie du Sport, Universit\u00e9 de Paris Cit\u00e9, 75012 Paris, France"},{"name":"Institut National du Sport, de l\u2019Expertise et de la Performance (INSEP), 75012 Paris, France"},{"name":"Centre d\u2019Investigation en M\u00e9decine du Sport, Assistance Publique\u2014H\u00f4pitaux de Paris, H\u00f4tel-Dieu, 75004 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8492-3579","authenticated-orcid":false,"given":"Adrien","family":"Sedeaud","sequence":"additional","affiliation":[{"name":"IRMES\u2014UMR 7329, Institut de Recherche M\u00e9dicale et d\u2019\u00c9pid\u00e9miologie du Sport, Universit\u00e9 de Paris Cit\u00e9, 75012 Paris, France"},{"name":"Institut National du Sport, de l\u2019Expertise et de la Performance (INSEP), 75012 Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1136\/bjsm.2006.032318","article-title":"Time-Motion Analysis and Physiological Data of Elite under-19-Year-Old Basketball Players during Competition","volume":"41","year":"2007","journal-title":"Br.
