Key takeaways
- A review of reviews consolidated 263 published reviews from an initial 12,087 records, mapping 21 research themes.
- Injury prevention programs reduce injury incidence between 25% and 65%, yet real-world uptake by clubs and coaches remains low.
- Average annual dropout in organised youth sport is about 24%, highest across mid-adolescence and among girls.
- Concussion reporting is widely underreported, with up to two-thirds of athletes concealing symptoms in some contexts.
- The evidence base is uneven: heavy on injury, training, and concussion; thin on policy, inclusion, Indigenous and disabled cohorts, and implementation science.
Abstract – via Flinders University
Youth sport is a dynamic and multifaceted field, encompassing diverse topics such as participation, retention, coaching, talent development, mental health, and wellbeing. While numerous systematic reviews have synthesised evidence on specific aspects of youth sport, the growing volume of these reviews has created a fragmented knowledge base. A systematic review of reviews is needed to consolidate existing evidence, identify overarching patterns, and highlight gaps in knowledge. This approach provides a comprehensive, high-level synthesis that can guide national sport policy, improve practice, and determine future research priorities.
This is particularly important in youth sport, where evidence-based interventions can have profound impacts on young people’s physical health, mental wellbeing, and lifelong engagement in sport and physical activity. By streamlining and evaluating the current evidence landscape, this review will offer clear, consolidated guidance for coaches, practitioners, policymakers, and researchers working to optimise youth sport environments and outcomes.

Why this review matters for operators and sponsors
Elliott and colleagues produced the first high-level landscape synthesis of youth sport research, consolidating 263 reviews and thousands of underlying studies to identify where evidence is robust and where it is missing. That matters because everyday decisions how a club trains coaches, whether a league adopts an injury prevention program, how a funder prioritizes grants depend on evidence that is often fragmented. The report flags practical, tested interventions such as neuromuscular injury-prevention programs, while also highlighting persistent gaps in adoption, measurement, and equity.
Injury prevention, what’s proven and what’s not
What the evidence shows. Multiple meta-analyses and reviews find injury prevention programs, for example structured warm-ups and neuromuscular training, substantially cut injury incidence. Reported reductions range from about 25% up to 65%, varying by sport and population. Female athletes and those with higher training loads show elevated injury risk. Surveillance methods differ across studies, which complicates direct comparisons.
Why this matters to operators. The interventions exist and work under trial conditions. The recurring problem is implementation. Clubs and grassroots coaches rarely sustain programs because of low awareness, insufficient coach support, and limited fidelity tracking. Investing in coach mentoring and simple fidelity checks yields higher chances of real-world impact than one-off workshops.
Practical step. If you run facilities or leagues, pilot an evidence-based warm-up IPP with mentor-led coach sessions and track adherence monthly for three seasons. That gives a measurable basis for injury reduction without major capital costs.
Participation and dropout clear problems, fuzzy measurement
What the review found. Nineteen syntheses covering participation and dropout show a persistent, multifactorial problem. Average annual dropout is about 24%, with mid-adolescence (ages 14–17) a high-risk period and girls disproportionately affected. Factors linked to dropout include poor enjoyment, unmet psychological needs, early specialisation, and socioeconomic barriers. The literature lacks standardised definitions of “dropout,” and most studies use self-report data with limited diversity.
Why this matters to operators and partners. High turnover translates into unpredictable demand for camps, leagues, and facility time. Sponsorship ROI depends on stable participation numbers. Fixes that target experience coaching quality, social belonging, programming variety are better evidence-aligned than purely price or marketing tactics. Investing in programming that boosts enjoyment and competence has stronger evidence for retention than incremental marketing spend.
Practical step. Develop a quarterly participant experience survey focused on enjoyment, competence, and social connection. Use results to change session formats and coach assignments. Test whether diversified programming (multi-sport exposure) improves retention at season end.
Concussion, reporting, and education
What the evidence shows. Sixteen reviews examined concussion incidence, stakeholder knowledge, and prevention. Contact sports have higher incidence, female athletes and those with prior concussion are at greater risk, and underreporting is common. Education improves short-term knowledge and reporting intentions among coaches and parents, but sustained behavioural change is limited.
Why this matters to operators and insurers. Underreporting raises liability and safety risks. Education alone is insufficient; coupled measures such as standardised surveillance, rule adjustments, coach enforcement, and return-to-play protocols produce stronger protective effects.
Practical step. Pair mandated brief annual training for coaches and parents with an anonymous reporting channel and an enforcement checklist for referees and league administrators. Measure reporting rates and return-to-play adherence quarterly.
Gaps that matter for strategic investment
The review identifies several priority knowledge gaps that map directly to investment opportunities:
- Implementation science: few studies evaluate adoption, fidelity, and sustainability of proven programs. Funded trials on implementation will move evidence into practice.
- Policy evaluation: the impact of rule changes, bio-banding, and competitive engineering lacks robust assessment. Pilot policy trials could yield high-value guidance.
- Equity and inclusion: Indigenous, culturally and linguistically diverse, low-income, and disabled cohorts are underrepresented. Targeted grants and community partnerships can fill this gap.
Looking ahead: strategic implications for executives and operators
- Prioritise implementation over invention. Proven injury and coach interventions exist. The highest-return investments are mentor-led rollouts, fidelity tracking, and integration into coach accreditation.
- Measure participation the same way every season. Standardised, short engagement metrics tied to actual retention help align programming and sponsorship value.
- Treat concussion policy as multi-component. Education plus enforcement, reporting channels, and standard surveillance yield stronger safety outcomes.
- Invest to diversify evidence. Funding targeted research for underrepresented groups or policy pilots will both improve practice and generate intellectual property for leagues and sponsors.
