What does IGF-1 stand for?

IGF-1 stands for Insulin-like Growth Factor 1. This peptide hormone plays a crucial role in growth and development, influencing cellular growth and regeneration. It is structurally similar to insulin, which is where the term "insulin-like" comes from. IGF-1 is primarily produced in the liver in response to growth hormone stimulation and is involved in anabolic processes, promoting muscle growth and repair, as well as overall tissue growth.

Understanding IGF-1 is essential for those studying sports nutrition and exercise physiology because of its significance in muscle recovery and development. The hormone affects how the body uses nutrients and promotes an increase in muscle protein synthesis, which is fundamental for athletes and individuals engaged in resistance training.

While other options mention related terms, they do not accurately represent the scientific nomenclature or function associated with IGF-1, reinforcing the importance of precise terminology in the field of sports nutrition.
