5. ENERGY 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.

6. ENERGY CONTINUUM TASK 1 Draw a diagram to explain the Energy Continuum Draw a diagram to explain the Energy Continuum

7. FACTORS AFFECTING THE ENERGY SYSTEM USED TASK 2 Present one of the following to the rest of the class; explaining how it affects the energy system used by athletes (the first one is already done): Present one of the following to the rest of the class; explaining how it affects the energy system used by athletes (the first one is already done): Exercise Intensity and Duration Energy System Threshold O2 Transport/Supply Food/Fuel available Enzyme Activation Levels Fitness Level

8. 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
