What was done
A rapid review of PubMed/Medline was conducted to assess the effects of early sport specialization (single-sport focus >8 months per year before age 18) in pediatric athletes. Authors extracted data on injury outcomes (focused on overuse injuries), functional and physical performance, sport success, and psychological outcomes, summarizing all included studies qualitatively.
What was found
The review included 93 studies representing 62,327 athletes (mean age 15.9 years; mean age at specialization 11.6 years). Early sport specialization was associated with increased risk of injury, worse functional and physical performance, decreased or absent benefit to sport success, and poor psychological outcomes. The abstract reports qualitative directions of effect with no pooled numerical effect sizes or confidence intervals.
Why it matters
This comprehensive synthesis indicates that intensive youth single-sport focus carries notable injury and mental health risks without conferring measurable competitive advantages over multisport participation.
Limits
The literature search was restricted to a single database (PubMed/Medline) and relied on qualitative descriptive synthesis rather than quantitative meta-analysis. The underlying evidence base comprises observational studies susceptible to recall bias, confounding, and selection bias.
