Aerobic and Anaerobic Exercise
Aerobic Exercise
Any form of exercise which is completed at an intensity that allows a plentiful supply of oxygen to be taken in by the lungs and used by the body
Summary equation of
Aerobic Exercise
Glucose + Oxygen --> Energy + Carbon Dioxide + Water
Sporting examples of
Aerobic Exercise
Marathon Running
Long-distance Cycling
Open-water Swimming
Anaerobic Exercise
Any form of exercise which involves short periods of high-intensity work which prevents the athlete from taking in enough oxygen to meet the energy demands of the exercise
Summary equation for
Anaerobic Exercise
Glucose --> Energy + Lactic Acid
Sporting examples of
Anaerobic Exercise
Weightlifting
100m Sprint
Triple Jump
Fuel for Exercise
Athletes need to replenish their fuel stores through the food that they eat
Different foods provide energy for different forms of exercise
Carbohydrates
Provide fuel for
Aerobic Exercise
Provide fuel for
Anaerobic Exercise
Converted to glucose before being used by the body
Can be stored in the body as glycogen
Fats
Require oxygen in order to produce energy
Provide fuel for
Aerobic Exercise
only once glucose stores have been used
Can be stored in the body in adipose tissue
Using Both Systems
Often, sports require athletes to work both aerobically and anaerobically during a competition
Different scenarios when an athlete would be required to use both of these energy systems when taking part in a sport
Team sports such as football and hockey
They require performers to work aerobically for most of the match when they are walking into a position or jogging around the pitch
Bursts of anaerobic work are frequently required in order to sprint to the ball or sprint past the opposition
Middle-distance athletic events
They will mostly require athletes to work aerobically in order to maintain their speed for most of the race
Sprint finishes require the athletes to work anaerobically in order to produce a short period of intense work
