TRANSCRIPT
ENERGY• The body needs energy to survive• The only form of energy the body uses is
called ‘ATP’• There are 3 (energy systems) ways in which
the body can create ATP• Intensity of exercise depends on which of the
3 systems is used to supply the fuel for ATP production
Creatine Phosphate• Supplies energy very quickly• Does not require oxygen so is classed as
anaerobic• Your muscles only stores around 10 seconds
worth of creatine phosphate before it is all used up
Lactic Acid• Supplies energy quickly but not as fast as C.P. • Stores for this energy production are higher
from 10 seconds 40 seconds• The waste product from this system Lactic
Acid makes the muscles feel sore and tired and will eventually stop
• This system is also anaerobic
Aerobic• Supplies energy a lot slower than the other
two systems• However this system can supply energy for as
long as required so long as there is food than can be used to create the energy
• This system requires oxygen which is the reason why its the slowest reaction
• This is known as Aerobic
AEROBIC/ANAEROBIC
Aerobic: Requires oxygen in a reaction
Anaerobic: No oxygen required for reaction
What do these two terms mean?
INTENSITY OF ACTIVITYSports require you to work at different speeds, intensity and durations.
A way to measure intensity is by how much energy they use. This can be measured in Kilocalories per hour
