Definition and History
Creatine is a naturally occurring compound found in small amounts in certain foods and synthesized in the body from amino acids. It primarily resides in muscle tissue and facilitates the production of adenosine triphosphate (ATP), the energy currency of cells.
The history of creatine supplementation began in the early 1990s when it was first popularized in sports nutrition. Early studies highlighted its potential to improve strength and increase muscle mass. Over time, it evolved from a niche supplement to a mainstream performance enhancer, used by athletes across various disciplines.
Mechanism of Action
Creatine works mainly by enhancing the body's ability to produce energy rapidly. When engaging in high-intensity exercise, the demand for ATP surges. Creatine phosphate replenishes ATP, allowing for prolonged exertion.
In more detail, during anaerobic activities, creatine donates a phosphate group to adenosine diphosphate (ADP) to reform ATP quickly. This rapid regeneration of ATP enables muscles to maintain performance levels far better than without supplementation.
Creatine supplementation leads to improved power output and higher training volumes, which can contribute to greater muscle gains over time.
Biochemistry of Creatine
The biochemistry of creatine is fundamental to understanding its role as a supplement in sports and cognitive performance.
