  1. ENERGY

  2. 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

  3. ENERGY SYSTEMS There are 3 energy systems 1.Creatine Phosphate 2.Lactic Acid 3.Aerobic

  4. 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

  5. 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

  6. 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

  7. AEROBIC/ANAEROBIC Aerobic: Requires oxygen in a reaction Anaerobic: No oxygen required for reaction What do these two terms mean?

  8. AEROBIC ACTIVITIES • FOOTBALL • MARATHON • TOUR DE FRANCE • BASKETBALL • 400M SWIMMING

  9. ANAEROBIC ACTIVITIES • 100M • WEIGHTLIFTING • GYMNASTICS • SHOT PUTT • 50M SWIMMING • 400M RUNNING

  10. INTENSITY OF ACTIVITY Sports 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

  11. INTENSITY OF EXERICSE HIGHEST INTENSITY LOWEST INTENSITY • 100m sprint • Marathon • Tour de France • Basketball • Squash • Swimming (recreational) • Tennis • Shot putt • Weightlifting • Javelin • Walking
