Nordic hamstring exercise break\u2010point angle (NBPA), rapid isometric hamstring strength (LLB), 20m sprint performance, and continuous angular knee extension velocity waveforms were assessed pre\u2010 and post\u2010intervention, and following a 2\u2010week detraining period. A significant main effect of time was observed for sprint, NBPA, and rapid isometric strength (\n                    <jats:italic>p<\/jats:italic>\n                    \u00a0&lt;\u00a00.05); however, Bonferroni\u2010corrected within\u2010group comparisons reached significance only for sprint performance in both groups, with no significant between\u2010group differences for any outcome. Equivalence testing supported comparable sprint adaptations between protocols but could not be established for eccentric or isometric hamstring strength. All discrete outcome measures were largely maintained or continued to develop following the detraining period though range\u2010specific eccentric strength appeared more sensitive to the training cessation. A combined low\u2010volume eccentric and isometric training approach may represent a viable alternative to higher\u2010volume eccentric programming for hamstring strength and speed development, although this should be approached cautiously to preserve neuromuscular qualities relevant to hamstring injury risk mitigation.\n                  <\/jats:p>","DOI":"10.1002\/ejsc.70257","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T12:13:24Z","timestamp":1790684004000},"source":"Crossref","is-referenced-by-count":0,"title":["Examining the Impact of Supramaximal Eccentric and Long\u2010Lever Isometric Training Protocols on Isometric Hamstring Strength, Nordic Hamstring Performance, and Sprint Speed"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-5232-5555","authenticated-orcid":false,"given":"Adam E.","family":"Sundh","sequence":"first","affiliation":[{"name":"School of Health and Society University of Salford  Salford UK"},{"name":"Chicago Bears Football Club  Lake Forest Illinois USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin S.","family":"VerVoort","sequence":"additional","affiliation":[{"name":"Department of Athletics Purdue University Northwest  Hammond Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4066-0591","authenticated-orcid":false,"given":"Nicholas J.","family":"Ripley","sequence":"additional","affiliation":[{"name":"School of Health and Society University of Salford  Salford UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8240-3101","authenticated-orcid":false,"given":"A.
