So the phosphocreatine system contributes about 12% of the energy needed for an all-out 2:00 race -- a good reason to make sure it's not totally depleted by too many long sprints immediately ...

ATP is the basic unit of energy for all living organisms on Earth, including humans, and to make it, the body relies on three different production systems (a.k.a. “metabolic pathways ...

That may not be the only benefit. A growing body of research suggests creatine may be good for brains as well as brawn. That ...

The second pathway, the glycolytic pathway, is the primary energy system used for exercise lasting from 15 seconds to three minutes. People running an 800-meter event, for example, use this ...

Creatine acts at the cellular level, where it is stored as phosphocreatine and spurs production of adenosine triphosphate (ATP)—an energy source used by cells. Most of the creatine that we consume ...

The creatine is then carried via in the circulatory system to storage sites, ... Some research has provided evidence that an increase in the phosphocreatine energy buffer as a result of creatine ...

Creatine supplements increase your phosphocreatine stores, allowing you to produce more ATP energy to fuel your muscles during high-intensity exercise (10, 11). This is the primary mechanism ...
