Delay Sport Specialization Until Late Adolescence, Experts Say

Early specialization not needed to reach elite level, delay optimizes chances of success, minimizes risk of injury and burnout

 

While some degree of sport specialization is required to achieve elite status, for most sports, intense training in a single sport to the exclusion of others should be delayed until late adolescence to maximize chances of success while minimizing risk for overuse injury and burnout, recommends a new study. (Jayanthi, 2012)

Based on a review of previous studies discussing sports specialization (e.g. intense, year-round training in a single sport to the exclusion of others sports), researchers in at Loyola Chicago, Chicago Children's Memorial Hospital and Northwestern found that:

  • with the exception of gymnastics, in which peak performance occurs before full maturation and thus requires intense training before puberty, it has not been consistently demonstrated that early intense training is essential for attaining an elite level in all sports;
  • most elite athletes, including world-class athletes, are more likely to start intense training later in adolescence;
  • for most sports, early diversification is more likely to lead to success;
  • early diversification provides the young athlete with valuable physical, cognitive, and psychosocial environments and promotes motivation;
  • early diversification followed by specialization may lead to more enjoyment, fewer injuries, and longer participation, contributing to the chances of success.
  • those soccer players who progressed to professional status at 16 years spent more time in unstructured soccer activities between the ages of 6 and 12 than those who did not;
  • spending more than 16 hours per week training significantly increased the risk of injury;
  • the risk of injury from intense training and specialization may be affected by age, competitive level, growth rate and pubertal maturation stage; and
  • early sports specialization may contribute to burnout and dropping out of sports.
The study appeared online ahead of print in the journal Sports Health: A Multidisciplinary Approach.

Matter of debate

While "there is general agreement that the number of hours spent in deliberate training and practice positively correlates with level of achievement in both individual and team sports, whether this intense practice must begin during early childhood and to the exclusion of other sports is a matter of debate,"  writes lead author, Dr. Neeru Jayanthi, a professor at Loyola Stritch School of Medicine in Chicago. 

The relative paucity of data has forced professional medical organizations (such as the National Athletic Trainers' Association and the American Medical Society for Sports Medicine to base their position statements on sports specialization and intense training in youth athletes to rely instead on expert opinion.

Trend towards specialization 

But what is not debatable is that the general trend in the United States has been towards early sports specialization, as evidenced by:

  • the growing number of travel leagues at 7 or 8 years of age;
  • an increase in the number of young Olympic athletes; and
  • A 2011 study of 519 U.S. Tennis Association junior tennis players, which found that 7 in 10 began specializing at an average age of 10.4 years old, with the specialization rate gradually increasing after age 14 so that, by the time an elite tennis player reached age 18, 95% were playing just tennis.  With such increased specialization, however, did not come increased enjoyment and satisfaction, with ratings decreasing in players more than 14 years old.

As a result, "youth sports participation has evolved from child-driven, recreational free play for enjoyment to adult-driven, highly structured, deliberate practice devoted to sports-specific skill development," says the study, an evolution likely the result of "society's increasing regard for successful athletes, who enjoy significant recognition and financial rewards for their achievements." 

One percent 

The problem is that few achieve that success.  "The reality is that few athletes achieve the elite or professional level," notes Dr. Jayanthi, with less than 1% of young U.S. athletes 6 to 17 years of age achieving elite status in basketball, soccer, baseball, softball or football, rates similar to those in Germany and Australia.
