ATP-PC system Adenosine triphosphate.- phosphocreatine

phosphocreatine is broken down into phosphate and creatine molecules. as with any bonds that are broken energy is released. The phosphate molecule bonds to ADP (adenosine diphosphate) which produced an ATP molecule. This ATP molecule is used within cells to make energy.

The 400m is considered a sprint event, and most of the recommended training for this event concentrates on anaerobic work, power development and technique. It is very rare for 400m runners to include steady running or even vVO2Max sessions. The proportion of anaerobic to aerobic requirements for this event are typically given as about 75%:25%.

The initial system the body uses is the ATP-PCr system, this is active for around 15 seconds, the body then taps into it's Anaerobic Glycolysis.

What is a high energy compound found only in muscle tissue?

Only in muscle tissue - phosphocreatine. There is a high energy compound in your muscles called adenosinetriphosphate phosphocreatine (or ATP - PC). This is the first energy system that your body uses and is in use for about 10 seconds (like when you are sprinting, powerlifting, etc.). This compound will 'recharge' over time. The two lower energy sytems used are: The anaerobic or lactic acid system, which lasts approx. 2 minutes. This is used in exercises af about the duration and intensity of the 400m sprint. And the aerobic system, which provides energy for long distance runs and continuous activity.
