Team Sports Beat Solo Training for Kids' Mental Health—Here's the Data

If you're a parent watching your child drift toward solo workouts or individual sports, I have one number for you: 35%. That's the reduction in depression risk for boys who play organized sports, according to a Swedish study of nearly 16,400 children (Lundgren et al., British Journal of Sports Medicine, 2025). For girls, the drop is 11%. But here's the kicker: those benefits are tied to organized sports—and the evidence increasingly points to team sports as the real mental health powerhouse. I'm not here to trash individual sports; I'm here to say that if you want to give your kid the best shot at thriving emotionally, team sports are the better bet.

The Numbers That Made Me Rethink Solo Training

Imagine you're the parent of an 11-year-old. You've read the headlines: 80% of adolescents worldwide aren't active enough (WHO, Physical Activity Fact Sheet). You want to change that, so you sign your kid up for swimming lessons or tennis—something that builds skill and discipline. Good instincts. But here's what the data says: in a U.S. study of over 11,000 children, team sport participation was linked to 19% lower withdrawn/depressed scores and 17% lower social problems, while individual sport participants actually showed higher anxiety and depression scores (ABCD Study, National Institutes of Health). That's not a typo. Individual sports were associated with a 16% increase in anxiety/depression. Now, I'm not saying individual sports cause mental health problems—correlation isn't causation—but the pattern is stark enough that I'd rather my kid be on a soccer team than a solo track grind.

Why Teams Work: The Belonging Effect

The researchers behind the ABCD Study attribute team sports' benefits to belongingness, supportive peers, friendship formation, shared responsibility, and collaborative goals—factors that are largely absent in individual sports. Think about it: when a kid is on a basketball team, they're not just exercising; they're part of a tribe. They have teammates who depend on them, a coach who knows their name, and a shared victory or loss. That's powerful. And it's not just for kids—young adults who sustained team sport participation from adolescence reported lower stress and better coping, and were less likely to experience panic disorder symptoms (ABCD Study, NIH). So the benefits aren't just a childhood thing; they carry into adulthood.

The Ugly Truth About Youth Sports Access

But here's where I get angry. The same data that shows these benefits also shows we're failing huge swaths of kids. The U.S. National Survey of Children's Health found that only 55.4% of youth ages 6-17 played sports in 2023 (Aspen Institute Project Play, State of Play 2025). That's better than the 2022 low of 53.8%, but still means nearly half of American kids are missing out. And the gaps are brutal: White students participate at 62.0%, while Black kids are at 56.1% and Hispanic kids at 51.6% (Int J Behavioral Nutrition & Physical Activity, 2025). Kids from lower socioeconomic backgrounds participate even less, due to access, safety, and financial barriers. And it's getting worse: the average number of sports a child plays has dropped 13% since 2019, to 1.63 (Aspen Institute Project Play, State of Play 2024). We're pushing kids to specialize early, and that's the opposite of what the evidence suggests we should do.

What You Can Do: A Concrete Plan

So, let's get practical. You're a parent of a 9-year-old. You have a limited budget. Here's my recommendation: put them in a team sport, not a solo one. It doesn't have to be expensive—check your local rec department. The Aspen Institute's Project Play has a 63X30 goal to get 63% of youth playing sports by 2030, and they're training coaches and investing in access (State of Play 2024, 2025). But you don't need to wait for the system to change. Start with one team sport—soccer, basketball, baseball, whatever's available. If your kid hates it, try another. The key is the team aspect.

Here's a quick checklist I've used with my own kids:

• Choose a sport that emphasizes cooperation over individual performance (e.g., basketball, soccer, volleyball).
• Look for programs that offer scholarships or sliding-scale fees if cost is an issue—many community leagues do.
• Encourage playing multiple sports, not early specialization. The data shows kids are specializing more, but the average is 1.63 sports—down from over two a decade ago (Aspen Institute Project Play, State of Play 2024). More variety is better.

And if you're worried about the time commitment? The WHO says any amount of physical activity is better than none (WHO, Physical Activity Fact Sheet). Even one practice a week is a start.

Bottom Line

The single best move you can make for your child's mental and physical health is to enroll them in a team sport. The data is clear: team sports are linked to lower depression, anxiety, and stress, while individual sports may carry risks. Don't let cost or convenience push you into a solo activity. Find a team, get your kid on it, and watch them thrive.
