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
