The phosphocreatine system acts to provide the main source of energy for sporting activities requiring short bursts of high-intensity exercise, making creatine the most useful, must-have supplement when it comes to sporting activities such as weight training, sprints, and those using explosive movement. Due to a large number of scientific studies that have been performed observing the effects of creatine, there is a whole host of evidence that illustrates how this useful supplement can boost performance, strength, and power through various mechanisms. Because creatine is a fuel source; it’s your body’s first choice of energy when performing the anaerobic exercise (such as running or cycling). By supplementing with it, you can act to increase creatine stores, providing your body with more energy for your training. In turn, this can allow you to lift heavier weights and increase the number of repetitions you can complete. By pushing your body that little bit further, extra micro-tears in your muscles can occur (the ache that you feel in your muscles from training). Once repaired, your muscles will build bigger, faster, and stronger.
