When researching this claim, I didn’t find anything that directly stated weightlifting makes a person shorter. Instead, the articles I found focused on whether weightlifting stunts growth, which already suggests that the claim is not true.
An article by Healthline discusses the effects of weightlifting and explains that strength training is actually very beneficial, providing many positive results. While some believe that weightlifting can make a person shorter, science does not support this idea. The article features Dr. Rob Raponi, a naturopathic doctor and certified sports nutritionist, who states, “The misconception that lifting weights stunts growth likely stems from the fact that injuries to growth plates in immature bones can stunt growth” (Healthline). This means that if growth is affected, it is due to improper form or injury, not weightlifting itself. In reality, any sport or physical activity carries some risk of injury, not just weightlifting. The concern in this article is primarily focused on children rather than adults. However, the research shows no direct correlation between weightlifting and stunted growth. Any impact on growth is more likely due to injury rather than the act of weightlifting itself.
In conclusion, this claim is false, as there are no articles that suggest weightlifting causes a person to become shorter. While I understand why some might believe it stunts growth, research does not support this idea. However, it is important to be cautious when weightlifting, as injuries particularly to growth plates can potentially affect a person's growth. Proper form is key to preventing such issues.
