Excessive physical exercise can harm adolescents

Excessive physical exercise can harm adolescents

Adolescence is a key period for acquiring bone mass. In adolescent athletes, the peak bone mass may present a greater increase, due to the mechanical stress imposed to the bones by the physical exercise practiced. There is consistent research confirming that moderate physical activity with weight support, such as running and jumping, has a more positive impact on bone deposition (bone quality) than activities that do not require weight support, such as swimming. However, in the puberty period, intense physical exercise does not always bring benefits to adolescents, particularly regarding skeletal growth. Some authors have shown that intense strength training in adolescents seems to lead to a decrease in levels of growth factors, which may compromise final height. In addition, excess physical activity is also related to stress fractures generated by repeated overloads.

Regarding strength training, the scientific literature does not confirm the hypotheses of injury to health or the development of children and adolescents. It is prudent for skilled technicians and physical educators to agree to avoid large blood pressure surges and training volumes. It is a fact that strength training can be a powerful stimulus to bone growth and development.

Appropriate training techniques and programs can greatly reduce the risk of injury, providing many physical and psychological benefits for the child. However, injuries can occur in the use of maximum weight surveys through inadequate training techniques and programs. Even so, the benefits of strength training for bone health outweigh the risks.
