What is the energy continuum concept?

The energy continuum describes how the different energy systems interact to provide energy for the human body during exercise. Key points-> All systems provides energy at any given time. At any given time, one energy system provides the most amount of energy. There are three energy systems within the energy continuum:ATP/PCR Lactic acid Aerobic system As exercise begins the PCR/ATP energy system provides the most energy for the human body, once exercise reaches around 10 seconds the lactic acid takes over and starts to provide the majority of energy. Lastly, the aerobic system will take over after around 3 minutes of exercise.
