Most likely, the myth that lifting weights stunts growth came from concern over kids causing damage to their growth plates if they participate in a strength training program.

 

Dr. Rob Raponi, a naturopathic doctor and certified sports nutritionist, says the misconception that lifting weights stunts growth likely stems from the fact that injuries to growth plates in immature bones can stunt growth.

 

However, he points out that this is something that can result from poor form, weights that are too heavy, and a lack of supervision. But it’s not the result of lifting weights correctly.

 

What this myth doesn’t mention is that participation in almost any type of sport or recreational activity carries a risk of injury. In fact, about 15 to 30 percent of all childhood fractures involve the growth plates.

 

Your growth plates are the cartilaginous areas of growing tissue at the ends of long bones (like the thigh bone, for example). These plates turn into hardened bone when young people reach physical maturity but are softer during development and are therefore more susceptible to damage.

 

But just because the growth plates are susceptible to damage doesn’t mean an adolescent or teenager should avoid lifting weights.

 

The shared thought among medical professionals is that weightlifting in kids under 18 is safe when properly applied, says Chris Wolf, DO, sports medicine and regenerative orthopedic specialist at the Bluetail Medical Group.
