Some reasons why endurance athletes should be using this stuff, creatine. I want to have a look at that over two videos. So let's give this a start. Your body's energy currency is known as ATP, adenosine triphosphate. And in the same way that most of the world would rely on the dollar as its main currency to fall back on, the adenosine triphosphate is what your body relies on as its energy currency. It's got reserves of ATP in each cell for very, very short bursts. It converts glucose into ATP for faster running or faster cycling, swimming, and it also converts fat into ATP energy for long-term things. And one of the things that creatine will do is it will help top up those levels. So that's reason number one. Reason number two is that ATP, or creatine at least, is going to help you with short, quick efforts. And I know what you're thinking. You're going, but hang on, I'm an endurance athlete. I'm looking at 2142 ultramarathons, half Ironman, full Ironman, long-distance bike rides. Why would creatine help me in my training if it's going to help with short-term bursts? Well, short-term bursts are really, really important when it comes to your training. And so for a runner, it might be hill sprints. For a swimmer, it might be a 50-meter at pace. For a cyclist, it might have a session where you're doing an easy period followed by one minute hard, an easy period, one minute hard, because you want to be developing that ability to push fast. You want to develop fast twitch muscle fibers. You're wanting to create that because you're going to rely on those things during the course even of an ultra-distance event. And so we want to be topping these things up on a regular basis. There's also good research that creatine is going to help you recover more quickly after a hard session. And remember, the ultimate fitness formula goes as follows. It's stress plus rest equals growth. And so it's not just pushing hard and then not resting and recovering properly. It's pushing hard, and then the all-important part is the recovery. And this is going to help you recover just a little bit better.
