Aerobic vs Anaerobic
Aerobic
Where you use oxygen to breathe while you are carrying out the moderate exercise and you can sustain the exercise for a long period of time.
Glucose and oxygen are brought to the muscles by blood.
This is where respiration takes place.
Any exercise between 65- 85% of your Heart rate is aerobic exercise
An example is a long distance runner.
Equation- Glucose + Oxygen → energy + CO2 + water
Waste Products- CO2 + water
Anaerobic
Where you don’t take in as much oxygen for the period of time that you are exercising intensively and you cannot sustain the exercise for long periods of time.
Anaerobic respiration is when no oxygen is used and just glucose.
An example is a sprinter.
Equation- glucose= energy + lactic acid
Waste product- Lactic acid (can lead to cramps)
Energy
Muscles need energy to work.
The energy comes from food we eat and is stored as glycogen in the muscles and liver.
Glycogen is converted back into glucose for use during exercise.
To work efficiently muscles also need plenty of Oxygen.
Energy Sources
Fats
Usually produce most of the body’s supply of energy.
Stored in fat cells and broken down during low intensity exercise.
Found in: cheese, butter, nuts, etc
Carbohydrates:
They are stored in the body as glycogen/glucose.
There is a limited supply and needs to be replenished.
There are 2 types of carbohydrates: Complex + simple.
Complex carbs are slower releasing energy (potatoes, pasta) whereas simple are quick releasing (fruits, isotonic drinks)
