Overview
Creatine has been widely studies within the strength and conditioning background and has been seen to show positive effects on performance assess the effects of creatine on sports requiring a range of different fitness components to be successful such as football. Previous research has suggested benefits of creatine supplementation such as increasing PCr (phosphocreatine) stores to aid ATP (adenosine triphosphate) production, increasing muscle water retention resulting in enhanced protein synthesis, reduced muscle damage and anti-inflammation. Identifying supplements that are scientifically proved to aid performance can help optimise training and develop physical ability of athletes to enhance performance.
