Does Lifting Weights Make You Shorter?
Introduction
A longstanding myth in fitness is that lifting weights, particularly heavy weights, can stunt growth and lead to a decrease in height. While it's true that certain exercises can compress the spine temporarily, these effects are typically short-lived and do not result in permanent height reduction.
Scientific Evidence
Numerous scientific studies have investigated the relationship between weightlifting and height. A comprehensive meta-analysis of 13 studies published in 2019 found no evidence that weightlifting stunts growth in healthy individuals. Furthermore, animal studies have shown that weightlifting can actually promote bone growth and density.
Growth Plates
Growth plates are located at the ends of long bones and are responsible for longitudinal growth. It's been suggested that excessive weightlifting can damage these growth plates. However, there is no scientific evidence to support this claim. In fact, studies have shown that weightlifting can strengthen growth plates and make them more resistant to injury.
Hormonal Effects
Weightlifting releases growth hormone, which is essential for bone growth. Researchers have found that regular weightlifting can increase growth hormone production, which may contribute to increased height over time.
Conclusion
Based on the current scientific evidence, it can be concluded that lifting weights does not make you shorter. In fact, it can actually contribute to increased height and overall bone health. It's important to emphasize, however, that proper technique and a gradual increase in weight are crucial to maximize the benefits and minimize the risk of injury.
