Players\u2019 physical demands were monitored with a local positioning system that was combined with inertial microsensors (WIMU PRO, RealTrack Systems SL). The accelerometer-derived metrics analyzed in this study were Player Load and DSL and other external-load metrics.\n \n Results<\/jats:bold>\n :\n <\/jats:italic>\n Player Load and DSL showed a\n very large<\/jats:italic>\n repeated-measure relationship, rm_corr\u2009=\u2009.781. Player Load showed a relationship with total distance (.967,\n almost perfect<\/jats:italic>\n ), high-speed running (.687,\n large<\/jats:italic>\n ), acceleration distance (.680,\n large<\/jats:italic>\n ), and deceleration distance (.661,\n large<\/jats:italic>\n ). Dynamic stress load showed a significant relationship with total distance (.662,\n large<\/jats:italic>\n ), high-speed running (.663,\n large<\/jats:italic>\n ), acceleration distance (.426,\n moderate<\/jats:italic>\n ), and deceleration distance (.412,\n moderate<\/jats:italic>\n ).\n \n Conclusions<\/jats:bold>\n :\n <\/jats:italic>\n Player Load and DSL are correlated but not interchangeable. Player Load correlates at least\n moderately<\/jats:italic>\n with all external-load measures monitored, with total distance and step count being\n almost perfect<\/jats:italic>\n . Although DSL is correlated well with impacts, step count, and jump count over 3 gravitational forces, it correlates to a lesser extent with all metrics. Finally, this study developed 2 multiple-regression models to explain the relative importance of external-load parameters.\n <\/jats:p>","DOI":"10.1123\/ijspp.2025-0300","type":"journal-article","created":{"date-parts":[[2025,11,11]],"date-time":"2025-11-11T17:46:59Z","timestamp":1762883219000},"page":"49-57","source":"Crossref","is-referenced-by-count":2,"title":["Assessing the Relationship and Convergent Validity of Player Load and Dynamic Stress Load in Basketball: A Multivariable Regression Analysis"],"prefix":"10.1123","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7126-2284","authenticated-orcid":true,"given":"Franc","family":"Garc\u00eda","sequence":"first","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Barcelona (UB), Barcelona Sport Sciences Research Group, Barcelona, Spain"},{"name":"Sports Performance Area, Futbol Club Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8388-8863","authenticated-orcid":true,"given":"Jordi","family":"Vicens-Bordas","sequence":"additional","affiliation":[{"name":"Sport, Exercise, and Human Movement (SEaHM) and Sport and Physical Activity Studies Centre (CEEAF), University of Vic-Central University of Catalonia, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Dawson","sequence":"additional","affiliation":[{"name":"School of Allied Health Sciences, University of Suffolk, Ipswich, United Kingdom"},{"name":"Faculty of Sport, Technology and Health Sciences, St Mary\u2019s University, London, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Hisham","family":"Jaward","sequence":"additional","affiliation":[{"name":"School of Technology, Business and Arts, University of Suffolk, Ipswich, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Espasa Labrador","sequence":"additional","affiliation":[{"name":"National Institute of Physical Education of Catalonia (INEFC), University of Barcelona (UB), Barcelona Sport Sciences Research Group, Barcelona, Spain"},{"name":"Sports Performance Area, Futbol Club Barcelona, Barcelona, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5373-2211","authenticated-orcid":true,"given":"Marco","family":"Beato","sequence":"additional","affiliation":[{"name":"School of Allied Health Sciences, University of Suffolk, Ipswich, United Kingdom"},{"name":"Department of Neurosciences, Biomedicine and Movement, University of Verona, Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"10","key":"r1","series-title":"Int J Sports Physiol Perform","doi-asserted-by":"publisher","first-page":"1109","DOI":"10.1123\/ijspp.2022-0460","article-title":"Impact of a 6-day official tournament on physical demands, perceptual\u2013physiological responses, well-being, and game performance of Under-18 basketball players","volume":"18","author":"Garc\u00eda F","year":"2023","unstructured":"Garc\u00eda F, Castellano J, Vicens-Bordas J, V\u00e1zquez-Guerrero J, Ferioli D.
