(2) Methods: A total of 19 football players (28 \u00b1 8 years; 172 \u00b1 12 cm; 79.3 \u00b1 22.3 kg) performed 10 sled-resisted training sessions with loads of 80% (\u00b12 kg) of their body mass on the day before the match (MD-1). Performance was assessed using a CMJ measured with the My Jump Lab app and sprint kinematics recorded with the 1080 Sprint system; both of these sensor-based technologies are validated for sports performance analysis. The CMJ was performed on MD-1 before the training and again on match day. Sprinting was evaluated before the sled-resisted training and again one week after it ended. (3) Results: These results suggest that sled training with heavy loads and low volume may not have acute effects on CMJ in amateur football players 24 h after it is performed, but there are chronic improvements in CMJ relative force and changes in sprinting after 10 weeks of sled-resisted training. (4) Conclusions: The findings of this study will enable football coaches and physical trainers to understand the changes in this training method to improve performance in amateur football players, using only three repetitions per player per week.<\/jats:p>","DOI":"10.3390\/s25216575","type":"journal-article","created":{"date-parts":[[2025,10,29]],"date-time":"2025-10-29T05:48:46Z","timestamp":1761716926000},"page":"6575","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Can Sled-Resisted Priming Training Enhance Performance in Amateur Football Players?"],"prefix":"10.3390","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9340-0519","authenticated-orcid":false,"given":"Alvaro","family":"Medina-Sanchez","sequence":"first","affiliation":[{"name":"IGOID Research Group, Department of Physical Activity and Sport Sciences, University of Castilla-La Mancha, 45071 Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2029-1277","authenticated-orcid":false,"given":"Jose Luis","family":"Felipe","sequence":"additional","affiliation":[{"name":"IGOID Research Group, Department of Physical Activity and Sport Sciences, University of Castilla-La Mancha, 45071 Toledo, Spain"},{"name":"Performance Analysis Department, UD Las Palmas, 35019 Las Palmas de Gran Canaria, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1741-5566","authenticated-orcid":false,"given":"Jorge","family":"Garcia-Unanue","sequence":"additional","affiliation":[{"name":"IGOID Research Group, Department of Physical Activity and Sport Sciences, University of Castilla-La Mancha, 45071 Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6296-6121","authenticated-orcid":false,"given":"Leonor","family":"Gallardo","sequence":"additional","affiliation":[{"name":"IGOID Research Group, Department of Physical Activity and Sport Sciences, University of Castilla-La Mancha, 45071 Toledo, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Alonso-Callejo","sequence":"additional","affiliation":[{"name":"IGOID Research Group, Department of Physical Activity and Sport Sciences, University of Castilla-La Mancha, 45071 Toledo, Spain"},{"name":"Department of Sports Sciences, Faculty of Medicine, Health and Sports, Universidad Europea de Madrid, 28670 Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,25]]},"reference":[{"key":"ref_1","unstructured":"Castellano, J., and Casamichana, D.
