ENERGY CONTINUUMENERGY CONTINUUM This is ‘the relative contribution of

each energy system to ATP re-synthesis determined by the intensity and duration of exercise.’

 In any sporting situation, energy is provided by all three energy systems, and the contribution of each is determined by the intensity and the duration of the exercise. Some activities/sports are mainly aerobic while others are anaerobic. Energy systems rarely work in isolation.

FACTORS AFFECTING THE ENERGY SYSTEM USED

TASK 2TASK 2Present one of the following to the rest of Present one of the following to the rest of the class; explaining how it affects the energy the class; explaining how it affects the energy system used by athletes (the first one is system used by athletes (the first one is already done):already done):

Exercise Intensity and Duration Energy System Threshold O2 Transport/Supply Food/Fuel available Enzyme Activation Levels Fitness Level

EXERCISE INTENSITY AND DURATION

A combination of exercise intensity and duration can determine the predominant energy system(s) being used

When exercise intensity is anaerobic (high intensity, short duration), then the ATP/PC and LA Systems will be predominant

If the exercise intensity is aerobic (medium/low intensity, long duration), then the Aerobic System will be predominant
