  6. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What is the oxygen debt? The extra carbon dioxide expelled as a result of exercise . The extra oxygen the body needs to perform exercise. The extra oxygen the body needs to recover from exercise. Oxygen consumption.

  7. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What does breathing after exercise help us do internally? Helps us remove carbon dioxide, replace oxygen & PC stores.

Used to make ATP, made from fat & stored in the liver & muscles. Used to make ATP, made from carbohydrate & stored in the stomach & muscles. Used to make ATP, made from carbohydrate & stored in the liver & muscles.

  10. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What food substances does the aerobic system use? Carbohydrates. Protein & carbohydrate. Fats & protein. Carbohydrates & fats.

  11. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What are the disadvantages of the aerobic system? It can only be used if enough oxygen is breathed out & it’s slow. It uses too much energy . It can only be used if enough oxygen is present & it’s slow. It creates carbon dioxide as a waste product.

  12. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What is the equation for working out maximum heart rate? 230 - your age 250 - your age. 210 - your age. 220 - your age.

  13. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What is a training zone? A heart rate area that allows you to work anaerobically A specific heart rate for rest. A range of heart rates that will create a specific training effect on a specific energy system. A heart rate area that allows you to work aerobically.

  14. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What is a training threshold? The heart rate that you must work above to enter a training zone. The heart rate that you must rest above to enter a training zone The heart rate that you must work below to enter a training zone. The heart rate that you must rest below to leave a training zone.

  15. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What type of training would you be doing if you were working above 80% of your max. heart rate? Anaerobic Aerobic & anaerobic. Aerobic. Strength training.

  16. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What do you have to know before you start training? Which energy systems your sport uses. Which energy systems your sport uses & how much & your training zones. Which energy systems your sport uses & how much & your training thresholds & zones. Your training thresholds & zones

  17. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What are the 3 energy systems? Glycogen, lactic acid & aerobic. ATP/PC, carbohydrate & aerobic. ATP/PC, lactic acid & aerobic. Anaerobic, lactic acid & aerobic

  18. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION What waste products does the aerobic system produce? Carbon dioxide & water. Oxygen & water. Carbon dioxide & nitrogen. Hydrogen & water.

  19. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION If you were training below 60% of your max heart rate how would you be training? Aerobically Anaerobically. You would be gaining no training effect. Aerobically & anaerobically.

  20. BRAIN SCAN ENERGY SYSTEMS NEXT QUESTION Which energy system do we use in general day to day activity? Anaerobic Aerobic. Glycogen. ATP /PC.

  21. EXTENSION QUESTIONS BRAIN SCAN EXAM QUESTIONS ENERGY SYSTEMS Which energy system is suited to endurance activity? END QUIZ Aerobic Protein & carbohydrate Anaerobic. ATP/PC.

  22. CORRECT!!!

  23. INCORRECT!

  24. EXTENSION QUESTIONS • What is glycogen & how is it made & where is it stored? • Where is ATP stored & how ling will this store last? • What chemical will remake ATP quickly & how much longer will we be able to work? • Why does the lactic acid system get used to make energy instead of the aerobic system? • How long will the PC & lactic acid system allow us to work hard for? • What is an oxygen deficit? ANSWERS

  25. EXAM QUESTIONS • What do the terms aerobic & anaerobic mean? (2 marks) • Why does the body produce lactic acid & how does the body react to a build up of it? (4 marks) • What is an oxygen debt & when is it likely to occur? (3 marks) • Energy for physical activity is produced aerobically & anaerobically. Choose 1 activity & explain how it uses energy. (5 marks) • What is meant by the term ‘threshold of training’? (1 mark) • Compare the energy produced for short & long distance events. (4 marks) • What is glycogen & give 2 places in the body where it is stored? (2 marks) • Carbon dioxide is a waste product of energy release. Name 2 others & how does the body get rid of waste products during physical activity? (4 marks) • What is aerobic fitness & how is it affected by high altitude? (5 marks) • How is food broken down into energy & how does the rate of this process affect physical performance? (4 marks) ANSWERS

  26. EXTENSION ANSWERS • 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.

  27. EXAM ANSWERS • 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.
