Energy systems:
Overview and ATP
Describe, explain and analyse the three
different energy systems and their use in
sport and exercise activities
What is energy?
• Energy is a property of objects which can be
transferred to other objects or converted into
different forms (Wikipedia, 2016)
• The "ability of a system to perform work" is a
common description, but it is misleading because
energy is not necessarily available to do work
(Wikipedia, 2016)
• Energy gives us the capacity to do stuff (Steve,
2016 – please do not reference)
