Aerobic Energy System
Which would be the dominant energy system in this physical activity?
ATP-PC System
Lactic Acid System
Aerobic System
The anaerobic glycolysis system
operates without oxygen
provides energy for about 10 seconds to 90 seconds
is used for high intensity exercise
all of the above
none of the above
For athletic events such as javelin and discus, the predominant energy system used is
aerobic system
anaerobic glycolysis system
ATP-PC system
The substance that accumulates in the muscle during anaerobic glycolysis is known as:
phosphate creatine
triglyceride
lactic acid
ATP
Which of the following fuels can be used to produce energy?
Carbohydrates
Proteins
Fats
all of the above
none of the above
The energy system used for a particular activity will depend on the:
intensity of the activity
duration of the activity
both of the above
none of the above
The speed of ATP production when the aerobic energy system is predominant is:
very fast
fast
slow
Our breathing rate increases and you start to breathe heavily, this happens because
More blood gets circulated around the body
We have started to perform a physical activity
To break down Lactic Acid and replenish energy supplies.
Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.
The burning sensation you feel during and shortly after exercise is largely due to
Proteins
Lactic Acid
Hormones
Acids
What is the function of carbohydrate?
To keep the body warm
To give energy to the body
For growth and repair of the body
To keep the eyes healthy
The body's main source of energy
Protein
Vitamins
minerals
Carbohydrates

No energy, energy
Energy, no energy
Oxygen, no oxygen
No oxygen, oxygen
ATP stands for what?
Aerobic Tri-potassium
Adenosine Tri-phosphate
Adrenaline Twitch Protein
Anaerobic Triple Phosphate
Why does the body require the three different energy systems?
It doesn't require three different systems
Different sports have different demands
Intensity and duration of different activities and the availability of oxygen
