Over the past 15 years, there has been an increase in youth sports participation with a concomitant increase in early year-round training in a single sport. Many factors contribute to the desire of parents and coaches to encourage early single sport specialization, including the desire to give the young athlete an edge in competition, pursuit of scholarships, and potential professional status, and the ability to label a young athlete as elite at an early age. Despite these perceived advantages…

Early Sport Specialization.
TLDR
The current understanding of ESS is summarized, evidence for and against its merits are reported, areas of future research are highlighted, and recommendations for orthopaedic providers involved in the care of young athletes are provided.
Implications for Training in Youth: Is Specialization Benefiting Kids?
TLDR
A history of pre-existing injuries is shown as a risk factor for future sports-related injuries, and strategies such as resistance training need to be imposed within a TRAINING REGIMen for youths.
The association between early specialization and performance level with injury and illness risk in youth elite athletes
TLDR
In a group of youth elite athletes entering a specialized Sport Academy High School program neither early single‐sport specialization nor performance level appears to represent risk factors for injury or illness after enrollment.
Early Sport Specialization Among Former National Collegiate Athletic Association Athletes: Trends, Scholarship Attainment, Injury, and Attrition
TLDR
Less than one-fifth of NCAA athletes surveyed specialized before age 15 years, and neither scholarship attainment nor time-loss injury rate was affected by early specialization, which is on the rise but is associated with increased burnout.
Factors That Drive Youth Specialization
TLDR
Young athletes are increasingly specializing in a single sport before starting high school, while intrinsic drive may identify healthy aspirations, extrinsic influences are prevalent in specialized athletes.
Early Single-Sport Specialization: A Survey of 3090 High School, Collegiate, and Professional Athletes
TLDR
Current HS athletes specialized, on average, 2 years earlier than current collegiate and professional athletes surveyed, challenging the notion that success at an elite level requires athletes to specialize in 1 sport at a very young age.
Early Sport Specialization: Effectiveness and Risk of Injury in Professional Baseball Players
TLDR
The study demonstrated a statistically significant higher rate of serious injury during a baseball player’s professional career in those players who specialized early, and should be encouraged not to participate in a single sport given the potential for an increased incidence of serious injuries later in their careers.
Youth Single-Sport Specialization in Professional Baseball Players
TLDR
The current trends toward early youth sport specialization within baseball are challenged, finding that the majority of professional baseball athletes studied did not specialize as youth and that those who did specialize did so at a mean age of 14 years.
Early Sports Specialization in Elite Wrestlers
TLDR
Elite wrestlers who specialize prior to age 12 years sustain a greater number of serious injuries before starting college than those who specialize at or after the age of 12 years.
Specialization patterns across various youth sports and relationship to injury risk
TLDR
Athletes in individual sports may be more likely to specialize in a single sport than team sport athletes, with higher training volumes and greater rates of overuse injuries than single-sport specialized athletes in team sports.

TLDR
Year-round training in a single sport beginning at a relatively young age is increasingly common among youth, and risks of early specialization include social isolation, overdependence, burnout, and perhaps risk of overuse injury.

More data needed on injury risk among young elite athletes
TLDR
Systematic injury surveillance of this highly competitive population is needed to monitor injuries, identify high risk sports, and ensure new knowledge on injury trends, which can form the basis for further research on injury risk factors, mechanisms, and in the final step, on injury prevention.

TLDR
Recommendations are provided based on current evidence regarding pediatric injury surveillance, identification of risk factors for injury, preparticipation physical examinations, proper supervision and education, sport alterations, training and conditioning programs, and delayed specialization.
Risk-Prone Pitching Activities and Injuries in Youth Baseball
TLDR
Pitching-related arm tiredness and arm pain were associated with increased risk of pitching-related injuries, but pitching on a travel baseball club, playing baseball exclusively, or playing catcher were not associated with arm problems.
