ANAEROBIC ENERGY SYSTEMS

This system consists of two energy pathways:  The ATP-CP (creatine phosphate) system and the ATP-LA (lactic acid) energy source.  The ATP-CP system requires no oxygen to supply five to eight seconds of maximum effort energy.  The CP energy system can be fully recharged after two to three minutes of rest.  The ATP-LA system also requires no oxygen allowing energy output to continue for up to 60 seconds.  Approximately one hour is needed to fully remove the lactic acid from the system.
