Glycogen is the substance used to make ATP. It is made from carbohydrate
that we eat in our food. It is stored in the liver & muscles.
ATP is stored in the muscles & will only for about 5-8 seconds of hard work.
Creatine phosphate will allow us to work for another 20 seconds.
The Aerobic system is slow & it takes time for oxygen to reach the muscles.
During this time the lactic acid system acts as a stop gap system to allow us
to work during this time.
About 1 minutes worth of hard work.
An oxygen deficit is when muscles need more oxygen than they are
receiving.

Work / exercise with oxygen & without oxygen.
It is produced in the absence of oxygen to break down glycogen for energy. Muscles get tired & muscle
contraction becomes painful.
The amount of oxygen that needs to be replaced after the body has worked without exercise on top of that
normally taken in. This debt will occur normally within the first 3 minutes of exercise & at the point of maximal
heart rate.
Aerobics/ sprinting (other relevant similar activities) - oxygen is used to break down glycogen for energy. The
aerobic system is a slow one which produces lots of energy & makes carbon dioxide & water as waste
products& will produce energy for long periods of time. In sprinting lactic acid is used to break down glycogen
& will work for a short time only, it makes energy quickly, but will only last up to 3 minutes.
Heart rate to work at or above to gain certain training effects.
Short- Phosphocreatine or lactic acid system used as energy is made in the absence of oxygen. Pc stores
last up to 30 seconds & is remade quickly after this time the lactic acid system takes over. Long - the aerobic
system is used but is slow, it makes lots of energy & will do for long periods as long as there is glycogen
available.
The substance used to make ATP that comes form carbohydrates & is stored in the liver & muscles.
Lactic acid, water , heat removed by circulation, sweating, vasodiloation, evaporation & radiation.
How well we use oxygen to work. The more efficient we are at it the fitter we are. At high altitude there is less
oxygen available as the air is thinner the higher you get. If you train high up the body will adapt to this by
using less oxygen to produce the same output. When you return to ground level there will be more oxygen
available so performance will be better as efficiency will be greater.
Aerobically with oxygen & anaerobically without oxygen. The longer you can resist fatigue anaerobically & the
quicker you can work aerobically the better the performance.
