Coaches & sports parents, the start of the school year brings excitement. It may also lead to an increase in overuse injuries among youth athletes.

At Performance OSM, we often see the following: repetitive stress, early sport specialization, and insufficient rest → tendonitis, stress fractures, and growth plate issues.

Here’s how you can help protect your athletes:
- Make rest & cross-training part of the plan
- Use warm-ups and strength work appropriate for young bodies
- Keep an eye out for warning signs like lingering pain, swelling, or changed performance

If there's concern, early evaluation & treatment make all the difference. We’re here to support athletes, coaches, & parents in keeping young players healthy, strong, and in the game.
