Creatine is a naturally occurring compound found in muscle cells. It plays a critical role in the production of adenosine triphosphate (ATP), the primary energy carrier in all cells. It has long been a buzzword in the fitness world, often associated with bodybuilders and gym-goers looking to boost strength and performance. But it does also benefit runners. Let’s break down everything you need to know about this powerful compound and its potential impact on your running performance.
The science behind creatine
The majority of the body’s creatine (around 95%) is stored in the muscles, where it helps generate ATP during high-intensity, short-duration activities like sprinting or heavy lifting. It is also present in smaller amounts in the brain, liver, and kidneys. While the body can produce creatine from amino acids glycine and arginine, it is also obtained through dietary sources, particularly from meat and fish.
What you need to know about creatine supplements
Creatine supplements, most commonly in the form of creatine monohydrate, have been popular among athletes and bodybuilders for decades. These supplements are designed to increase the body’s creatine stores, thereby enhancing ATP production during intense physical activities. While the use of creatine has often been associated with weightlifting and sports requiring explosive power, recent studies have begun to uncover its potential benefits for endurance athletes, including runners.
Understanding what creatine is and how it functions is crucial for athletes considering its incorporation into their training regimen. This foundational knowledge allows for an informed decision on whether creatine supplementation could be beneficial for their specific athletic goals and how to use it effectively and safely.
Different Types of Creatine Supplements
When it comes to creatine supplements, there are several types available on the market, each with its own set of characteristics.
Creatine monohydrate
The most widely studied and commonly used form is creatine monohydrate. This form has been extensively researched and proven to be effective in increasing muscle creatine content, enhancing performance, and supporting recovery. Creatine monohydrate is also known for its cost-effectiveness and availability, making it a popular choice among athletes.
Creatine ethyl ester
Another form of creatine is creatine ethyl ester, which is marketed as having better absorption rates compared to creatine monohydrate. However, research on creatine ethyl ester is limited, and some studies suggest that it may not be as effective in increasing muscle creatine levels as creatine monohydrate. Other forms of creatine, such as creatine hydrochloride (HCl) and buffered creatine, also claim to offer improved solubility and absorption, but the scientific evidence supporting these claims is still inconclusive.
Creatine nitrate
This is another variant that combines creatine with nitrate. This form is believed to offer the benefits of both creatine and nitrate, including improved endurance and nitric oxide production. However, like other alternative forms of creatine, more research is needed to validate its efficacy and safety. Ultimately, creatine monohydrate remains the gold standard due to its extensive research backing and proven effectiveness. Athletes considering creatine supplementation should weigh the available evidence and choose a form that aligns with their needs and preferences.
