Creatine is a naturally occurring molecule in the body that plays a key role in explosive energy metabolism. It helps to drive periods of short burst power output; like the first few reps in a set, or the explosive drive from the starting blocks. During exercise, intramuscular stores of creatine reload ATP molecules, the “energy machine of muscle”, for last between-set recovery.Creatine supplements increase your phosphocreatine stores, allowing you to produce more ATP energy to fuel your muscles during high-intensity exercise. This is the primary mechanism behind creatine's performance-enhancing effects. improves high-intensity exercise performance.The most common is creatine monohydrate, a dietary supplement that increases muscle performance in short-duration, high-intensity resistance exercises. Studies show that taking these supplements benefit athletes during strength training, notably weightlifting and cycling.
