Does lifting weights at an early age stunt growth?
The question of whether lifting weights at an early age can stunt growth has been a topic of debate among parents, coaches, and fitness enthusiasts for years. While some argue that weightlifting can hinder the growth plates in children, others believe that it can be a safe and beneficial activity for young athletes. This article aims to explore the scientific evidence and provide insights into this controversial topic.
In the first place, it is important to understand what growth plates are. Growth plates, also known as epiphyseal plates, are areas of cartilage located at the ends of long bones in children and adolescents. These plates are responsible for the lengthening of bones as they grow. Once the growth plates close, typically around the age of 18 for girls and 20 for boys, the bones stop growing in length.
Research has shown that weightlifting can indeed cause stress on the growth plates. However, the key factor is the intensity and technique of the weightlifting exercises. Low-intensity weightlifting, such as light resistance training or bodyweight exercises, is generally considered safe for children and adolescents. On the other hand, high-intensity weightlifting, particularly with heavy loads, can potentially increase the risk of growth plate injuries.
One study published in the Journal of Orthopaedic & Sports Physical Therapy found that children who engaged in high-intensity weightlifting were more likely to experience growth plate fractures compared to those who did not participate in weightlifting. However, the study also noted that the risk of growth plate fractures was low, and the majority of fractures occurred during high-impact activities such as soccer or basketball.
Moreover, it is crucial to emphasize proper technique and supervision when weightlifting at an early age. Coaches and parents should ensure that young athletes are using appropriate form and gradually increasing the intensity of their workouts. This can help minimize the risk of growth plate injuries and promote safe and effective growth.
In conclusion, while there is a potential risk of growth plate injuries associated with weightlifting at an early age, the evidence suggests that low-intensity weightlifting can be a safe and beneficial activity for children and adolescents. By focusing on proper technique, gradual progression, and supervision, the risk of stunting growth can be minimized. Ultimately, the decision to engage in weightlifting should be based on individual circumstances, considering the child’s physical development, fitness goals, and overall well-being.
