Are Kids More Likely to Develop Growth Plate Injuries From Sports or Weight Training?

One of the biggest myths in youth athletics is that lifting weights will “stunt growth” or damage a child’s growth plates.

Meanwhile, many young athletes are:

• Playing one sport year-round

• Traveling constantly for tournaments

• Practicing multiple times per week

• Throwing, jumping, sprinting, and cutting year after year with little recovery

So what actually places growing athletes at greater risk?

Current research suggests that properly supervised strength training is generally very safe for youth athletes, while repetitive sports specialization and overuse may pose a much greater risk for growth plate irritation and overuse injuries.

At MIGHT Strength & Performance Therapy, we often educate parents that the issue is usually not strength training itself.

The bigger issue is often:

• Excessive repetitive loading

• Early sport specialization

• Poor recovery

• High training volume

• Lack of movement variety

• Inadequate strength capacity

What Are Growth Plates?

Growth plates (physes) are areas of developing cartilage located near the ends of long bones in children and adolescents.

These regions are still developing and are generally weaker than mature bone and surrounding connective tissue.

Because of this, growing athletes are more vulnerable to:

• Overuse injuries

• Repetitive stress injuries

• Growth plate irritation

• Bone stress injuries

Common areas affected include:

• Shoulder

• Elbow

• Knee

• Wrist

• Ankle

Sports Participation Is Often the Bigger Contributor

Research has consistently shown that early sports specialization and repetitive year-round training are associated with higher injury rates in youth athletes.

Examples include:

• Little League shoulder

• Little League elbow

• Gymnast wrist

• Osgood-Schlatter disease

• Sever’s disease

These conditions are commonly linked to repetitive loading during growth.

A large review on physeal injuries in youth sports found that growth plate injuries are frequently associated with organized sports participation and repetitive overuse demands.

Early Specialization Increases Risk

Many young athletes today specialize too early.

Instead of playing multiple sports and developing broad movement skills, athletes may:

• Play one sport 10–12 months per year

• Participate on multiple teams simultaneously

• Train at high intensity year-round

• Perform repetitive movements thousands of times

Research shows that athletes who specialize early are at significantly greater risk for overuse injuries compared to multi-sport athletes.

The American Academy of Pediatrics has also raised concerns regarding intensive training and early specialization in young athletes.

What About Weight Training?

This is where many parents are surprised.

Modern research does not support the idea that properly supervised strength training stunts growth or commonly damages growth plates.

In fact, appropriately designed youth resistance training programs may help:

• Improve strength

• Increase coordination

• Improve bone health

• Enhance athletic performance

• Reduce injury risk

Research reviews have shown that supervised youth strength training programs can actually reduce sports-related injuries when properly implemented.

The important distinction is:

Proper strength training ≠ maximal lifting with poor supervision.

Most reported growth plate injuries associated with weight rooms historically involved:

• Improper technique

• Excessive loads

• Lack of supervision

• Accidents

• Unsafe equipment use

Not well-structured youth performance programs.

The Real Problem: Load Without Capacity

The body adapts well to stress when it is progressed appropriately.

Problems usually occur when:

• Training volume exceeds recovery

• Athletes are fatigued year-round

• Kids lack foundational strength

• Recovery is poor

• Sleep and nutrition are inadequate

• Athletes perform repetitive motions excessively

Ironically, appropriate strength training may actually help prepare young athletes for the demands of their sport.

Why Strength Training May Actually Protect Young Athletes

When done correctly, strength training can help improve:

• Force absorption

• Joint stability

• Movement mechanics

• Tissue resilience

• Neuromuscular control

This may reduce overload on vulnerable structures during sports participation.

Instead of making kids fragile, properly dosed resistance training can help make them more resilient.

Signs of Possible Growth Plate Irritation

Parents and coaches should monitor for:

• Persistent joint pain

• Swelling

• Limping

• Pain during throwing or jumping

• Tenderness near a joint

• Decreased performance

• Pain that lingers after activity

Pain that continues for weeks should not simply be ignored as “growing pains.”

Our Approach With Youth Athletes

At MIGHT Strength & Performance Therapy, we focus on helping youth athletes:

• Build strength safely

• Improve movement quality

• Develop athletic foundations

• Manage training loads

• Reduce overuse stress

• Stay healthy long term

The goal is not just short-term performance. The goal is creating resilient athletes who can continue playing and performing for years to come.
