Energy Systems #2

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).

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.

What is the major energy system used in long distance running?

• ATP-CP

• Anaerobic

• Aerobic

You would use Anaerobic system in

• 400m run, hurdles

• 100m sprint, 50m swim

• Triathlon, Tour de France, Marathon
