Public Health"],"abstract":"\n Background<\/jats:title>\n The transition from youth academy participation to elite senior professional soccer is marred by physical volatility, non-linear development, and elevated injury risk, placing the long-term well-being of young athletes at the intersection of sports science and public health. Traditional chronological age group categorization exacerbates selection bias through the Relative Age Effect (RAE) and often fails to safeguard growing athletes from workload-induced injuries.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aims to evaluate a multi-center, maturation-indexed public health intervention protocol designed to optimize athletic output, balance internal\/external training loads, and systematically reduce non-contact lower-limb injuries in professional academy soccer players across early- to post-pubertal sub-groups (U13\u2013U16).<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n This protocol outlines a 24-week cluster-randomized controlled trial. A cohort of 240 elite male youth soccer players [categorized as Tier 3: Highly Trained\/National Level per (\n 1<\/jats:xref>\n ) aged 12\u201316\u202fyears] will be recruited from professional football academies (K\u202f=\u202f4,\n n<\/jats:italic>\n \u202f=\u202f60 per cluster). Academies will be randomized in a 1:1 ratio to either standard chronological age-group care (Control) or a maturation-indexed framework (Experimental). The experimental arm integrates bio-banding protocols (grouping players by percentage of predicted adult height [%PAH]), progressive neuromuscular conditioning (FIFA 11+), and microtechnology-driven load threshold monitoring. Primary outcomes include injury incidence rate (per 1,000\u202fh of exposure) and changes in physical performance profiles (sprint speed, repeated sprint ability, and vertical jump height). Secondary outcomes encompass internal-to-external load ratios and psychological wellness metrics (assessed via the Hooper index).\n <\/jats:p>\n <\/jats:sec>\n \n Discussion<\/jats:title>\n By treating elite youth soccer player development through a preventive public health lens, this trial will provide scalable evidence regarding the efficacy of biological maturation models. Aligning training load with physiological readiness aims to mitigate systemic youth injuries, reduce elite talent drop-out rates, and update international academy guidelines.<\/jats:p>\n <\/jats:sec>","DOI":"10.3389\/fpubh.2026.1937270","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T15:48:54Z","timestamp":1789400934000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Soccer health, performance, and injury prevention in highly trained youth soccer players: a public health approach"],"prefix":"10.3389","volume":"14","author":[{"given":"Musa Lewis","family":"Mathunjwa","sequence":"first","affiliation":[{"name":"Department of Human Movement Science, University of Zululand","place":["KwaDlangezwa, South Africa"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seymur","family":"Aliyev","sequence":"additional","affiliation":[{"name":"Department of Coaching, Nakhchivan State University","place":["Nakhchivan, Azerbaijan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"317","DOI":"10.1123\/ijspp.2021-0451","article-title":"Defining training and performance caliber of elite athletes: a framework for research studies","volume":"17","author":"McKay","year":"2022","journal-title":"Int J Sports Physiol Perform"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"e0277901","DOI":"10.1371\/journal.pone.0277901","article-title":"Peak match acceleration demands differentiate between elite youth and professional football players","volume":"18","author":"Thoseby","year":"2023","journal-title":"PLoS One"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"150","DOI":"10.3390\/sports10100150","article-title":"The physical demands of match-play in academy and senior soccer players from the Scottish premiership","volume":"10","author":"Morgans","year":"2022","journal-title":"Sports"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"632","DOI":"10.3390\/life16040632","article-title":"Injury epidemiology in elite U17 football players: a prospective study across six competitive seasons","volume":"16","author":"Pranji\u0107","year":"2026","journal-title":"Life (Basel)"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"83","DOI":"10.1016\/j.ptsp.2024.03.004","article-title":"Mitigating the risks of lower extremity injuries in soccer: a comprehensive analysis of lower extremity injury rates in soccer between 2014 and 2023","volume":"67","author":"Sheehan","year":"2024","journal-title":"Phys Ther Sport"},{"key":"ref6","first-page":"244","article-title":"A systematic review and meta-analysis of various injury prevention programs in youth soccer players","volume":"20","author":"Castillo","year":"2025","journal-title":"J Orthop Surg Res"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"338","DOI":"10.55860\/xm1gsn52","article-title":"Prevention of anterior cruciate ligament injuries in female soccer: effectiveness and adherence to the FIFA 11+ protocol","volume":"21","author":"Barbato","year":"2025","journal-title":"J Hum Sport Exerc"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"168","DOI":"10.3390\/jfmk10020168","article-title":"The effect of peak height velocity on strength and power development of young athletes: a scoping review","volume":"10","author":"Retzepis","year":"2025","journal-title":"J Funct Morphol Kinesiol"},{"key":"ref9","doi-asserted-by":"publisher","first-page":"2178","DOI":"10.1519\/JSC.0000000000004540","article-title":"Longitudinal development of sprint performance and force-velocity-power characteristics: influence of biological maturation","volume":"37","author":"Edwards","year":"2023","journal-title":"J Strength Cond Res"},{"key":"ref10","doi-asserted-by":"publisher","first-page":"355","DOI":"10.1186\/s13102-025-01424-8","article-title":"Determinants of agility across biological maturation status in soccer players","volume":"17","author":"Ito","year":"2025","journal-title":"BMC Sports Sci Med Rehabil"},{"key":"ref11","first-page":"45","article-title":"Growth, maturation, and injury risk in youth soccer players: current evidence and practical implications","volume":"10","author":"Monasterio","year":"2024","journal-title":"Sports Med -
