This quasi-experimental applied study quantified neuromuscular changes during a four-week individualized in-season strength-training program in 21 youth basketball players (age: 16.4\u2009\u00b1\u20091.3 years). Players were stratified into high (&gt;0.57), neutral (0.45\u20130.57), or low (&lt;0.45) baseline DSI tertiles to prioritize training emphasis (maximal strength, mixed, or ballistic\/plyometric, respectively). Participants completed three individualized sessions per week alongside regular basketball training. Pre- and post-intervention measures included countermovement jump (CMJ) height and peak force, isometric squat (ISOBelt) peak force, and estimated one-repetition maximum (1RM) back squat. DSI was subsequently calculated from CMJ and ISOBelt peak force values. The high DSI tertile showed increases in ISOBelt peak force (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.004,\n                    <jats:italic>d<\/jats:italic>\n                    \u2009=\u20092.10) and estimated 1RM back squat (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.002,\n                    <jats:italic>d<\/jats:italic>\n                    \u2009=\u20091.84), accompanied by a reduction in DSI (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001,\n                    <jats:italic>d<\/jats:italic>\n                    \u2009=\u2009\u22121.56), whereas CMJ outcomes showed no statistically significant changes across tertiles (all\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05). The neutral tertile showed an increase in estimated 1RM back squat (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.002,\n                    <jats:italic>d<\/jats:italic>\n                    \u2009=\u20090.89), although no significant interaction effects were observed. During the competitive season, DSI-based profiling was associated with distinct within-tercile neuromuscular changes over four weeks; findings should be interpreted as observational outcomes within an applied in-season context and may assist practitioners in guiding individualized in-season strength-training prioritization.\n                  <\/jats:p>","DOI":"10.1371\/journal.pone.0350739","type":"journal-article","created":{"date-parts":[[2026,6,15]],"date-time":"2026-06-15T17:22:22Z","timestamp":1781544142000},"page":"e0350739","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":0,"title":["Neuromuscular changes during a four-week individualized in-season strength-training program based on the dynamic strength index in youth basketball players: A quasi-experimental study"],"prefix":"10.1371","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-1476-4654","authenticated-orcid":true,"given":"Casado-Mart\u00ednez","family":"P","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romero-Moraleda","family":"B","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1515-9711","authenticated-orcid":true,"given":"Gonz\u00e1lez-Garc\u00eda","family":"J","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2026,6,15]]},"reference":[{"issue":"1","key":"pone.0350739.ref001","doi-asserted-by":"crossref","first-page":"111","DOI":"10.1007\/s40279-017-0794-z","article-title":"The Activity Demands and Physiological Responses Encountered During Basketball Match-Play: A Systematic Review","volume":"48","author":"E Stojanovi\u0107","year":"2018","journal-title":"Sports Med"},{"issue":"1","key":"pone.0350739.ref002","doi-asserted-by":"crossref","first-page":"504","DOI":"10.52082\/jssm.2024.504","article-title":"Effectiveness of an Individualized Training Based on Dynamic Strength Index on Sprinting, Jumping and Change of Direction Performance in Basketball Players: A Randomized Controlled Trial","volume":"23","author":"J Ple\u0161a","year":"2024","journal-title":"J Sports Sci Med"},{"key":"pone.0350739.ref003","doi-asserted-by":"crossref","first-page":"59","DOI":"10.2478\/hukin-2020-0014","article-title":"Dynamic Strength Index: Relationships with Common Performance Variables and Contextualization of Training Recommendations","volume":"74","author":"TJ Suchomel","year":"2020","journal-title":"J Hum Kinet"},{"issue":"3","key":"pone.0350739.ref004","doi-asserted-by":"crossref","first-page":"71","DOI":"10.3390\/sports5030071","article-title":"A Comparison of Dynamic Strength Index between Team-Sport Athletes","volume":"5","author":"C Thomas","year":"2017","journal-title":"Sports (Basel)"},{"issue":"1","key":"pone.0350739.ref005","doi-asserted-by":"crossref","first-page":"303","DOI":"10.3390\/app15010303","article-title":"Testing Consistency: Analyzing the Reliability of Two Lower Limb Isometric Force Measurements in Strength-Trained Athletes","volume":"15","author":"F Giuliano","year":"2024","journal-title":"Applied Sciences"},{"key":"pone.0350739.ref006","unstructured":"Tsopanidou A.
