Traditional youth training often emphasizes aerobic endurance and heavy resistance training, which may not optimally develop such power.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Purpose<\/jats:title>\n                    <jats:p>To compare the effects of five different training modes, including optimal power load (OPL), resistance training (RT), high-intensity interval training (HIIT), jump training (JT) and combined training (CT), on the lower limb explosive strength of 12\u201319 years old adolescent soccer players.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic review and network meta-analysis of randomized controlled trials was conducted, with 29 studies identified from databases such as PubMed, Web of Science, Embase, EBSCO, Cochrane Library, CNKI, WanFang, and VIP. Data were analyzed using Stata 17.0, with effect sizes calculated for 10 m and 30 m sprint times, squat jump (SJ), and countermovement jump (CMJ).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All five training interventions showed statistically significant improvements lower-limb explosive power compared to control training. Network meta-analysis suggested that CT might be the most effective for improving SJ height (MD = 4.86 [95%CI:2.67 to 7.05], P &amp;lt; 0.01, SUCRA = 82.7) and CMJ height (MD = 3.33 [95%CI:2.15 to 4.52], P &amp;lt; 0.01, SUCRA = 65.7), while the conventional meta-analysis suggested that OPL might be the most effective for reducing 10 m sprint time (MD = \u22121.47 [95%CI: \u22122.68 to \u22120.26] and 30 m sprint time (SMD = \u22122.06 [95%CI: \u22123.40 to \u22120.72]). The effects of other interventions such as RT, HIIT, and JT were also significant, but the effects were relatively small. Subgroup analyses suggest that this effect may be most pronounced in younger athletes, with diminishing returns observed in older adolescents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Combining resistance and plyometric training is likely to be a highly effective strategy to optimize limb explosive power development in youth football players within the training parameters examined. The findings suggest that coaches could consider incorporating CT and OPL into their programs to enhance both sprinting and jumping capabilities. Future research may need to explore the long-term impacts and physiological mechanisms underlying these training effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Systematic Review Registration<\/jats:title>\n                    <jats:p>\n                      <jats:ext-link>https:\/\/www.crd.york.ac.uk\/PROSPERO\/view\/CRD420251249378<\/jats:ext-link>\n                      , Identifier CRD420251249378.\n                    <\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fphys.2026.1769079","type":"journal-article","created":{"date-parts":[[2026,3,19]],"date-time":"2026-03-19T05:23:29Z","timestamp":1773897809000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":4,"title":["Effects of different training on lower limb explosive power in youth soccer players: a systematic review and network meta-analysis"],"prefix":"10.3389","volume":"17","author":[{"given":"HuaiBin","family":"Tan","sequence":"first","affiliation":[{"name":"College of Physical Education, China West Normal University","place":["Nanchong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZhiGao","family":"Yan","sequence":"additional","affiliation":[{"name":"College of Physical Education, China West Normal University","place":["Nanchong, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cong","family":"Shao","sequence":"additional","affiliation":[{"name":"China Football College, Beijing Sport University","place":["Beijing, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"YiFei","family":"Lin","sequence":"additional","affiliation":[{"name":"Sports Training College, Tianjin University of Sport","place":["Tianjin, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,19]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"2769","DOI":"10.1519\/JSC.0000000000003221","article-title":"Effects of adding vertical or horizontal force-vector exercises to In-season general strength training on jumping and sprinting performance of youth football players","volume":"35","author":"Abade","year":"2021","journal-title":"J.
