Energy Systems Introduction

This article will give an introduction to energy systems , describe what they are and how these can be applied.

Our body, when we move or workout, is constantly supplying the muscles with the energy to maintain what we are doing.

The way in which energy is made depends on a number of factors, these will include:

  • training age
  • training level
  • intensity
  • duration

Essentially, an athletes ability to create this energy rely on things such as:

  • the development of the energy type being used by that particular athlete.
  • size of the muscle – although the larger mass requires more energy, it will also produce more.
  • diet and nutrition

Over the next few weeks, we will look in to the energy systems and how we can develop them during our training.

The 3 energy systems are:

  • Aerobic System
  • ATP-PC or Anaerobic Alactic
  • Glycolytic System or Anaerobic Lactic

These three energy systems work together to ensure that we can meet the demands of what is being asked. This may be affected by the intensity and the amount that we rest between “work”.

ATP is the molecule for storing and transferring energy in the cells, it is the body’s currency of energy. The ATP is produced by the body either with oxygen or without. Each of the energy systems above produce ATP at different rates. There is a balance between ATP creation and the how long the output can be sustained for.

Sports such as Powerlifting and Weightlifting, rely on the alactic system, require large amounts of power output but over a short duration. Whereas a Marathon runner would require longer periods of power and will rely on the aerobic system.
