Why 70 percent of kids quit sports by age 13

According to a poll from the National Alliance for Youth Sports, around 70 percent of kids in the United States stop playing organized sports by the age of 13 because "it's just not fun anymore."

I have three kids, all of whom play sports, and my oldest is about to turn 13. I may not have understood why this was happening a few years ago, but sadly, knowing what I know now, the mass exodus of 13-year-olds from organized sports makes perfect sense to me.

"It's not fun anymore" isn't the problem; it's a consequence of a number of cultural, economic and systemic issues that result in our kids turning away from organized sports at a time when they could benefit from them the most.

Playing sports offers everything from physical activity, experiencing success and bouncing back from failure; to taking calculated risks and dealing with the consequences; to working as a team and getting away from the ubiquitous presence of screens.

Our middle-schoolers need sports now more than ever.

Here are the reasons I think it's become less fun for kids to play sports, and why they are taking an early retirement.

• It's more competitive as kids get older. As children get closer to high school, the system of youth sports is geared toward meeting the needs of more competitive players, and the expectations placed on them increase.

Often the mentality is that most of the kids who quit at 13 are the ones who wouldn't make a varsity team in high school anyway.

Those who stick around find that being on a team means a greater commitment of time and effort. It also means being surrounded by people who care very much about the outcome.

This, consequently, brings with it the potential for experiencing disappointment or being the cause of it.

There is nothing wrong with any of that, and it can teach incredibly important lessons about hard work, resiliency and character - but it's not for everyone.

• Our culture no longer supports older kids playing for the fun of it. The pressure to raise "successful" kids means that we expect them to be the best. If they're not, they're encouraged to cut their losses and focus on areas where they can excel.

We see it in middle school orchestra, where a kid who doesn't make first chair wonders if it's worth continuing to play.

If a seventh-grader doesn't make a select team for soccer, she starts to wonder if maybe it's time to quit altogether.

For the small minority of kids who are playing a sport at an elite level and loving it, the idea of quitting in middle school is probably unthinkable. But for everyone else, there are fewer opportunities to play, a more competitive and less developmental environment in which to participate, and lots of other things competing for their time after school.

• There is a clear push for kids to specialize and achieve at the highest possible level. Increasingly kids are pressured to "find their passion" and excel in that area (be it music, arts, sports, etc.).

There are certainly kids for whom this is true, but it is not the norm (despite the expectations of college admissions officers). For many, there's a strong argument against this trend, because the message is essentially to pick one thing and specialize in it (to the exclusion of pursuing other interests).

For young athletes, early specialization can be harmful in terms of long-term injuries, and it does little to increase one's overall chances of later collegiate or professional success.

Perhaps more importantly, the underlying message that "I have to be the best or I've failed" is deeply harmful to kids.

This is absolutely mirrored and reinforced in school, where the environment is increasingly test- and outcome-driven.

Sports could be pivotal in teaching kids how to fail and recover.

• There is a cost to be competitive and not everyone is willing or able to pay it. For kids, playing at a more competitive level can mean having to prioritize their commitments and interests and work tirelessly.

Training year-round, expensive equipment, individual coaching, camps, tournaments and participation on travel and select teams in many places are no longer really considered "optional" for success in youth sports, at least not heading into high school.

The investment of time and money is substantial. That contributes to an environment where kids of lower-income or single-parent families are shut out of the game.

• And, of course, it's just the age. At 13, kids generally find themselves with more (and more challenging) school work. Most are also encouraged to start choosing what interests them the most and what they're best at. There's no longer time for them to do as much they did in elementary school.

Some of the major social and emotional changes that 13-year-olds experience also predispose them to making decisions such as quitting sports. The CDC describes it on its developmental milestones page as a "going back and forth between high expectations and lack of confidence."

Kids become more focused on - and influenced by -their friends, many of whom are also walking away from organized youth sports.

Any discussion about being 13 also needs to include social media, smartphones and the Internet. According to the Pew Center's Internet Research Study, most U.S. kids receive their first cellphone or wireless device by the age of 12. Between the ages of 13 and 17, 92 percent of teens report being online every day, and 24 percent are online "almost constantly."

As kids become teenagers, their priorities change. How they socialize, study and spend their time changes with them.

These things collectively represent a perfect storm.

The system of youth sports is set up to cater to more elite players as they approach high school, leaving average kids with fewer opportunities. Our culture encourages specialization and achievement, which actively discourages kids from trying new things or just playing for fun.

And all of this converges at a time when they're going through major physical, emotional and social changes as well as facing pressure to pare down their interests and focus on school.
