We hypothesized that increased lower limb forces during loading would enhance positive work output during push\u2010off. Fifteen recreationally active men with good jumping ability (22.3\u00a0\u00b1\u00a04.5\u00a0years, 1.85\u00a0\u00b1\u00a00.06\u00a0m, and 79.1\u00a0\u00b1\u00a09.6\u00a0kg) performed maximal CMJ with and without AEL using handheld dumbbells equivalent to 20% body mass.

Effective jump height increased by 2.1\u00a0cm with AEL (0.548\u00a0\u00b1\u00a00.046\u00a0m) compared with bodyweight CMJs (0.527\u00a0\u00b1\u00a00.036\u00a0m). However, total lower\u2010limb joint work during push\u2010off, squat depth, and most lower\u2010limb electromyography parameters did not differ between conditions. Right ankle peak power and work during push\u2010off were lower with AEL, indicating a reduced ankle contribution despite improved jump height. These results do not support the claim that AEL enhances lower\u2010limb work output. Instead, increased center\u2010of\u2010mass work may have originated from segments not included in the joint\u2010level analysis, such as the trunk and upper body. Our findings suggest the hypothesis that altered whole\u2010body coordination, rather than greater lower\u2010limb work, contributed to the performance enhancement.\n                  <\/jats:p>","DOI":"10.1002\/ejsc.70228","type":"journal-article","created":{"date-parts":[[2026,7,25]],"date-time":"2026-07-25T05:34:41Z","timestamp":1784957681000},"source":"Crossref","is-referenced-by-count":0,"title":["Accentuated Eccentric Loading Increases Maximal Countermovement Jump Height Without Changes in Overall Lower Limb Kinetics and Energetics"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3216-7521","authenticated-orcid":false,"given":"Eric Yung\u2010Sheng","family":"Su","sequence":"first","affiliation":[{"name":"School of Human Movement and Nutrition Sciences The University of Queensland  Brisbane Queensland Australia"},{"name":"School of Exercise and Nutrition Sciences Queensland University of Technology  Kelvin Grove Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0761-1819","authenticated-orcid":false,"given":"Timothy J.","family":"Carroll","sequence":"additional","affiliation":[{"name":"School of Human Movement and Nutrition Sciences The University of Queensland  Brisbane Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6720-1961","authenticated-orcid":false,"given":"Dominic J.","family":"Farris","sequence":"additional","affiliation":[{"name":"School of Human Movement and Nutrition Sciences The University of Queensland  Brisbane Queensland Australia"},{"name":"Public Health and Sport Sciences Faculty of Health and Life Sciences University of Exeter  Exeter Devon UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7366-3348","authenticated-orcid":false,"given":"Glen","family":"Lichtwark","sequence":"additional","affiliation":[{"name":"School of Human Movement and Nutrition Sciences The University of Queensland  Brisbane Queensland Australia"},{"name":"School of Exercise and Nutrition Sciences Queensland University of Technology  Kelvin Grove Queensland Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,24]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0000000000000498"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.8.2.181"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1242\/jeb.110296"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelekin.2020.102438"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2013.845680"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1152\/japplphysiol.90571.2008"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005768\u2010199611000\u201000009"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003677\u2010200107000\u201000002"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1055\/s\u20102008\u20101026076"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0000000000001630"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1080\/14763141.2026.2623454"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejsc.70033"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005768\u2010200102000\u201000024"},{"key":"e_1_2_12_15_1","volume-title":"Essa's Student Manual for Health, Exercise and Sport Assessment.
