This energy is stored in our cells and is called
Oxidative triphosphate (OTP)
adenosine criphosphate (ATC).
Adenosine triphosphate (ATP).
Anaerobic means
without oxygen (ATP – PC and Lactic acid systems)
"with oxygen", and refers to the use of oxygen in the body's energy generating process (Aerobic energy system).
Aerobic means

"with oxygen", and refers to the use of oxygen in the body's energy generating process (Aerobic energy system).
How long does the ATP-CP system last?
2mins+ Long term energy
0 seconds up to 2 minutes Short term high intensity
Immediate high intensity (0-10seconds)
How long does the Anaerobic system last?
2mins+ Long term energy
0 seconds up to 2 minutes Short term high intensity
Immediate high intensity (0-10seconds)
How long does the Aerobic last?
2mins+ Long term energy
0 seconds up to 2 minutes Short term high intensity
Immediate high intensity (0-10seconds)
How does our body know when to work anaerobically rather than aerobically?
When the heart and lungs cannot deliver enough oxygen to the muscles to produce energy aerobically, the body switches to anaerobic energy production.
When you stop heavy breathing the body switches.
When the energy system is depleted because of the intensity and duration of the activity.
There is an overlap of both aerobic and anaerobic systems they work and switch on and off when required.

When does O2 Deficit occur?
Before the exercise
At the start of the exercise
During Steady state
At the end of the exercise
What is VO2 Max?
Volume of oxygen
maximum amount of oxygen we can use.
Difference between what oxygen we need and what we get.
How much oxygen ewe use during steady state
Which type of recovery is quicker at reducing lactate?
passive
active
static stretching
fluids
Passive recovery is best for recovering what?
lactate
oxygen
Phosphate creatine
Glucose
which is the correct way to show VO2 max?
mml
ltrs
mmols
ml/kg/min
What is OBLA?
lactate above O2 levels
Lactate starts to rise
lactate rises above 4 mmols
exercise can not be maintained due to lactate.
When does an athlete arrive at their lactate threshold?
when they can no longer maintain intensity
when there is a non linear change in blood lactate.
when their lactate levels go above 4 mmols
During steady state
Which best describes the use of ATP-PC?
high rate of energy release & high capacity of release
low rate of energy release & high capacity of release
high rate of energy release & low capacity of release
low rate of energy release & low capacity of release
Which best describes the use of ATP-aerobic system?
high rate of energy release & high capacity of release
low rate of energy release & high capacity of release
high rate of energy release & low capacity of release
low rate of energy release & low capacity of release
Why would an athlete need a high level of aerobic capacity if they mainly used their ATP-LC system?
They wouldn't.
More oxygen helps break down lactate
More oxygen supports the ATP-PC system
What is the definition of oxygen debt?
Amount of oxygen used for aerobic activity minus amount of oxygen actually used
Amount of oxygen needed at the end of a physical activity to break down any lactic acid
During oxygen debt, the lactic acid is removed from
Liver
Muscles
Lungs
Heart
In order to recover the fatigue, the lactic acid is...
taken to muscles
taken away from muscles
converted to galactose
converted to glucose
An oxygen debt occurs in muscles when...
more carbon dioxide has been produced
the breathing rate increases
anaerobic respiration has taken place
the pulse rate increases
The extra oxygen needed is to oxidise lactic acid into...
carbon dioxide and oxygen
oxygen and water
carbon dioxide and water
carbon dioxide, water and oxygen
To repay the oxygen debt, we need to take in deep, gasping breaths at the end of physical activity
True
False
The extra oxygen breathed in is to (multiple answer)
maintain higher than resting breathing rate, heart rate and temperature
remove excess carbon dioxide from the body
gradually decrease body temperature
break down and oxidise lactic acid.
What does EPOC stand for?
Extra Post-exercise Oxygen Consumer
Excess Post-exercise Oxygen Consumption
Extra Post-exercise Oxygen Consumption
Excess Pre-exercise oxygen consumption
A good way to recover from from activity is to...
rehydrate
refuel with food
cool down
ice bath
What two systems make up for the lack of oxygen during the oxygen deficit stage of exercise?
ATP-PCr
Cellular Respiration
Glycolysis
Krebs Cycle
EPOC during the recovery phase allows for what to happen? Click all that apply
PCr replenishment
Lactate Metabolism
Ventilation Recovery
Temperature Recovery
The lactate threshold is defined as
The maximal exercise intensity an individual can maintain with little or no lactate accumulation for an extended period of time
The point at which blood lactate begins to accumulate in large quantities in the blood
The point at which lactate starts to decrease in the blood
The point at which lactate accumulation is higher than lactate removal
OBLA represents the point at which blood lactate
abruptly decreases
Increases slightly
Increases exponentially
Levels off
In order to increase your lactate threshold, you should train with ________ effort and __________ recovery periods.
High, long
Hard, moderate
High, short
