Carbo loading, also known as carbohydrate loading, is a well-known term in sports and fitness circles. It involves consuming a high amount of carbohydrates before an athletic event to provide the body with sufficient energy to perform at its peak. However, synonymous terms with carbo loading are sometimes used to describe the same practice. These synonyms include glycogen loading, glycogen supercompensation, and carbo replenishment. Each of these terms refers to the same thing, which is the process of increasing the amount of glycogen stored in the muscles to improve athletic stamina and performance. Regardless of the term used, carbo loading remains an essential technique in the world of sports and fitness.
