you have a bigger oxygen debt after anaerobic exercise because your not using oxygen when you exercise.
1)aerobic is with oxygen and anaerobic is without air.
2)because some activities you just use not a lot of oxygen and some you don't go on for long but aerobic you go on for a lot longer so you need more oxygen.
3)because some sports you need to have a burst of energy so you don't you and oxygen but also you just jog so you use aerobic so you can go on for longer.
4)because some positions in football you just do a lot of short sprints such as striker but some other positions you have to pace yourself out so you don't loose you energy as quick so you can go on for longer.
ATP-CP System
This is the system used for short bursts of high-intensity work lasting approximately 10 seconds or less. and also is just short bursts of energy this is because the energy source runs out really quickly.
Lactic Acid System
The lactic acid system is also know as the lactic fresh hold it starts working after 10 seconds and allows you to work at a high intensity for between 60 to 90 seconds not as high intensity as ATP system. after 90 seconds this fuel will also run out and you wont be able to work at this intensity anymore.
Aerobic system
Aerobic system is where you cant run flat out. when you are running in a marathon you wouldn't go flat out because you would run out of oxygen and you wouldn't be able to keep going.
