ATP-PC System -- provides energy for approximately 20-30 seconds of intense work (e.
The total muscular stores of ATP-PC are very small, limiting the amount of obtainable energy.
In order to accommodate the body's need for an efficient, high-powered ATP-PC energy system, the brunt of the training procedures should fall within the parameters of a high-intensity, short duration, moderate recovery protocol.
For the ATP-PC system, an all-out effort completed under the 30-second intervals is essential, thus an appropriate distance must be determined for each run/drill.
The ATP-PC system's ability to produce high-intensity efforts up to around 30 seconds in duration make it the predominate energy source of the system.
The purpose of our interval running program is to enhance the ATP-PC system and the lactic acid system.
However, it's the rapid availability rather than the quantity of ATP-PC that makes it so useful.
There is also a shift in emphasis from the LA system to the ATP-PC system, thus preparing the athletes for specific energy needs of their sport.
Upon completion of this preparatory phase, the distances should be gradually reduced in order to shift the emphasis from the ATP-PC-LA system to the ATP-PC system.
