Creatine use in athletes Creatine is the second most commonly used supplement in college athletes. It is listed by the US Food and Drug Administration as a “generally recognized as safe” ingredient. However, NCAA does not allow schools to distribute creatine to athletes, but it is not a banned supplement.
Creatine is a nonessential amino acid produced by the liver from arginine and glycine (1,3). Most creatine will be maintained through dietary consumption like meat and supplementation can lead to higher intra-muscular levels. Creatine is stored in skeletal muscle and plays a critical role in the phosphocreatine shuttle.
Supplementation of creatine will increase intramuscular stores of phosphocreatine, which transfers a phosphate group from ADP to make ATP. The phosphocreatine shuttle is responsible for the ATP requirements during short and high intensity activity. Reviews have shown that creatine supplementation can increase power in short bouts.
The increased creatine stores have been found to improve performance in HIIT. In adolescents, creatine supplementation will increase intra-muscular water and increase muscle volume. Equation showing transfer of phosphate to ADP to make ATP The primary side effects of creatine use are muscle cramps, weight gain, and GI upset.
Creatine will cause water to be drawn into muscle, which may lead to dehydration in athletes playing in hot temperatures. Due to the theoretical risk of dehydration, it is recommended that athletes on creatine drink six to eight glasses of water per day. The elevated weight gain is also thought to occur due to the increase in water retention.
If you are experiencing symptoms that may be related to creatine use in athletes, it is important to see a sports medicine physician. Early evaluation and treatment typically lead to better outcomes. Do not ignore pain or symptoms that are limiting your activity.
