These adaptations resulted in more quadriceps dominant activity with increased stabilizing activity of gluteus medius, while hamstring activity decreased due to the lower angular knee extension during flight times with increasing resisted loads.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study suggests that while resisted sprinting is an effective tool for increasing force production demands, higher resisted loads (&gt; 50% velocity decrement) are associated with progressively different kinematic and neuromuscular patterns, likely reflecting the combined effects of increased force demands and thereby reduced running velocity.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/tsm2\/2139446","type":"journal-article","created":{"date-parts":[[2026,10,14]],"date-time":"2026-10-14T10:50:11Z","timestamp":1791975011000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Acute Effect of Different Resisted Sprint Loads on Joint Kinematics and Electromyographic Activity in Experienced Sprinters"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4481-4490","authenticated-orcid":false,"given":"Roland van den","family":"Tillaar","sequence":"first","affiliation":[{"name":"Department for Sports Science and Physical Education Nord University  Levanger Norway  nord.no"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2303-6001","authenticated-orcid":false,"given":"Sam","family":"Gleadhill","sequence":"additional","affiliation":[{"name":"College of Health Adelaide University  Adelaide Australia  adelaide.edu.au"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8156-243X","authenticated-orcid":false,"given":"Pedro","family":"Jim\u00e9nez-Reyes","sequence":"additional","affiliation":[{"name":"Sports Sciences Research Centre Rey Juan Carlos University  Madrid Spain  urjc.es"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9101-9759","authenticated-orcid":false,"given":"Ryu","family":"Nagahara","sequence":"additional","affiliation":[{"name":"Faculty of Sports and Budo Coaching Studies National Institute of Fitness and Sports in Kanoya  Kanoya Japan  nifs-k.ac.jp"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,14]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1519\/jsc.0b013e31816611ea"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1519\/ssc.0000000000000555"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1515\/humo-2017-0013"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s40279-018-0947-8"},{"key":"e_1_2_9_5_2","article-title":"The Effect of Resisted Sprint Training on Acceleration: A Systematic Review and Meta-Analysis","volume":"17","author":"Aldrich E.
