Energy Systems Explained 3 – Anaerobic (Lactic) System

Once the body’s ATP-PC stores are used up (~10 secs), it is time for the anaerobic (lactic) energy system to contribute. It is the predominant ATP supplier for activities lasting over ~ 10 seconds, but less than ~ 2 minutes. The function of this energy system is to breakdown stored

Energy Systems Explained 2 – ATP-PC System

ATP is the “energy currency” of the human body; in other words, all activities which require energy (such as beating of the heart, growing hair, breathing, jumping jacks, etc…) use ATP as the “fuel”. An explanation of the body’s “energy systems” actually discusses how ATP is created, rather than what

Energy Systems Explained

In previous posts (part I, part II, part III), we dealt with energy intake and storage within the human body. In this upcoming series, we will explore the next chapter of the energy utilization process by discussing the different energy systems which make up human metabolism. All movement by the
