Worksheet time: 8mins
During rest, energy is produced mostly
aerobically with oxygen
aerobically without oxygen
anaerobically with oxygen
anaerobically without oxygen
The ATP-PC energy system
utilises carbohydrates
needs the presence of oxygen
is used for endurance type activities
provides energy for up to about 10 secs of high intensity work
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 fuel source for anaerobic glycolysis is:
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 steady state indicates that the:
aerobic system is being used
anaerobic glycolysis system is being used
ATP-PC system is being used
anaerobic energy system is being used
EPOC stands for
Excess Pre-exercise Oxygen Consumption
Excess Post-exercise Oxygen Consumption
Energy Producing Oxygen Consumption
Energy Pathways Oxygen Consumption
Oxygen deficit occurs when:
there is a build up of lactic acid in the muscles.
a balance between the energy required by working muscles meets the rate of oxygen and delivery for aerobic ATP production.
the body's maximal level of oxygen uptake is reached.
there is a time delay or shortfall when the aerobic energy system fails to meet the body's oxygen demand.
Anaerobic threshold is defined as:
the physiological point during exercise at which lactic acid starts to accumulate in the muscles
the balance between oxygen demand and oxygen consumption
the maximum rate of oxygen consumption measured during exercise
the moment when the body is starved of oxygen
EPOC is proportional to:
intensity of exercise.
duration of exercise.
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
The quantity of ATP produced when the ATP-PC system is predominant is:
very limited (approximately 1 ATP during resynthesis)
limited (approximately 3 ATP during resynthesis)
unlimited (approximately 36 ATP during resynthesis)
non existent
