Early Sports Specialization

Early Sports Specialization

Early Sport Specialization (ESS)

Before I explain why, lets briefly get on the same page with a definition for Early Sport Specialization (ESS). Typically ESS refers to year-round (for at least 8 months) intensive training or competition in an organized sport by young athletes (<12 years of age) while excluding all other sports.

Injury Risk

One of the most studied problems with early specialization is increased injury risk compared to peers. The biggest factor contributing to this increased risk was participation in any individual sport for greater than 8 months of the year3. This is especially true in baseball pitchers where pitching for more than 8 months per year was correlated with a 500% increase in risk for Tommy John surgery. (I discuss this and other risk factors for UCL injury in my blog “Minimizing the Risk for UCL Injuries in Throwers” *hyperlink). Across all sports there is an increased injury risk of 1.81 times in highly specialized athletes compared to their multi-sport peers5.

The Biomechanics of the baseball throw:

Baseball fans thrive on interesting facts and statistics, but out of all of these facts, the science behind throwing a baseball has to be the most fascinating. The way that an elite athlete’s body can act as a coiled spring, transmitting the necessary forces to turn a baseball into an eye-blur is truly awe-inspiring. During the throw the elbow functions as a hinge joint, going through rapid extension at about 2400°/s for a professional pitcher. (Which is the equivalent of saying that in 1 second the arm could whip around 360° nearly 7 times). Accelerating to this incredible speed places a force on the Ulnar Collateral Ligament (UCL) of your elbow reaching 64Nm (nearly 50lbs).4 Not surprisingly, there is some fallout over time due to the transmission of this high force.
