The ATP-PC system uses what as it's fuel:
oxygen
glucose
phosphocreatine
fats
The ATP-PC system only lasts 10-12 seconds because:
It is high intensity and people can only do high intensity for short periods
it is a system operating without oxygen and therefore muscles become starved and needs to slow down
It is a system that operates with oxygen and lactic acid and the combination upsets the bodies operation
Most people aren't fit enough to hit 85% heart rate
The LACTIC ACID system relies upon which fuel to operate:
glucose from food
oxygen
phosphocreatine
fats
Which of the following options is the byproduct of the Lactic Acid system
fat burning
oxygen burning
protein usage
lactate formation
How long does the LACTIC ACID system operate for?
10 - 12 seconds
1 - 2 minutes
over 5 minutes
for as long as needed
What is the benefit of exercising within the Lactate threshold?
Makes you faster or stronger
helps to burn fat
creates efficiency within the body so that it can develop the capacity to be in that zone for longer
prevents boredom in training
p
The AEROBIC energy system utilizes which of the following for it's primary fuel:
phosphocreatine
glucose from food
protein
glucose and fats
Why would a coach include training of the aerobic energy system into a training program?
To fill in the gaps between the important sessions
to create a strong base level of fitness in an athlete and maintain it
as recovery
it is only suitable for athletes doing long distance training
What actually happens chemically when the ATP-PC system is accessed by the body (this one is for you Elysse!)
The body breaks down the ATP-PC molecule to create ADP and as a result, energy is released
ADP is formed is contains adenosine and two phosphate groups
Once the system is at rest, the body resynthesises the ADP and phosphates to re-create ATP
All of the above
The energy system used FIRST by the body when exercising is:
ATP-PC
Lactic Acid
Aerobic
ADP
