Aerobic and Anaerobic training
9/17/2018
Take register and circulate to check homework has been completed – 5 minutes for those who have not completed

2. Starter: Aerobic or Anaerobic

3. Learning Challenges
Understand the difference between aerobic and anaerobic exercise
Understand what EPOC is
Analyse the recovery process

4. Glucose + oxygen = energy + carbon dioxide + water
Aerobic Exercise
Aerobic exercise takes place in the presence of oxygen. When exercise is over a long period of time at a moderate to low intensity, the heart can supply all the oxygen the working muscles need.
When working aerobically, energy comes from carbohydrates, which are converted into glucose and oxygen. Carbon dioxide and water are produced as by-products. Sweat releases water and respiration releases CO2.
Aerobic exercise is the body’s preferred way of working because lots of energy can be produced with few harmful by-products.
Examples: marathon running
Glucose + oxygen = energy + carbon dioxide + water
Aerobic exercise
Working at a low to moderate intensity so that the body has time to use oxygen for energy production and can work for a long time.
Intensity
The amount of energy needed to complete an activity. Working at a high intensity requires a large amount of energy. Working at a low intensity requires less energy.
Students validate home learning worksheets and take photos of slides if necessary

5. Glucose = energy + lactic acid
Anaerobic Exercise
Anaerobic exercise takes place in the absence of oxygen. When exercise is short in duration and high in intensity, the heart and lungs cannot supply enough blood and therefore oxygen to the working muscles.
When working anaerobically, the muscles produce a waste product called lactic acid. As lactic acid builds up in the muscles, they become painful, fatigued and unable to continue working as efficiently. Therefore, the body can only work anaerobically for a short period of time (approximately 60 seconds maximum).
Examples: sprinting; Olympic weightlifting
Glucose = energy + lactic acid
Anaerobic exercise
Working for short periods of time at a high intensity without oxygen for energy production.
Lactic acid
A mild poison and waste product of anaerobic respiration.
Students validate home learning worksheets and take photos of slides if necessary

6. Activity 1: What is EPOC?
Watch the video and answer the following questions
What does EPOC stand for?
When does it occur?
How does it affect the body?
Extension:
Link back to your spirometer trace learning. Can you sketch a spirometer trace for Eddie Hall?
Watch video
Answer questions as a group
Make notes in book
Extension: spirometer trace

7. Excess Post-exercise Oxygen Consumption (EPOC)
The amount of oxygen needed to recover after exercise. It is characterised by an increased breathing rate and deeper breathing after exercise.
EPOC occurs after anaerobic exercise.
Breathing rate is faster and deeper.
EPOC replenishes the body with Oxygen.
It enables the body to convert lactic acid into glucose, carbon dioxide and water

EPOC is sometimes known as oxygen debt, but this term is now outdated.

8. Activity 2: The recovery process research
Station 1
Cool down
Station 2
Manipulation of diet
Station 3
Ice baths or massage
Extension:
Which of these methods are you most and least likely to use?
Do you think any of them will be outdated in the future?
Identify…
Describe…
Explain…
Add an example…
DOMS
Delayed Onset Muscle Soreness, the pain you feel in your muscles the day after exercise.
Each table works on a given topic as per stations (a rainbow technique could be used)
They must prepare to feed back to the class at the end
Textbooks are needed for research
