Across
- 3. The percentage of this fuel being used as an energy source decreases as the exercise intensity increase because there are many complex chemical reactions involved making it harder to break down
- 4. The anaerobic glycolysis system is used during _____-_____ durations
- 6. The aerobic system is used during ____ durations
- 9. Acute muscular system responses to exercise are those that occur in the _____ muscles themselves
- 10. When at ____, the body’s need for ATP is relatively small
- 11. Ability to continue to work at very high intensities whilst in the presence of harmful metabolic byproducts (anaerobic capacity)
- 13. As exercise intensity increases, oxygen uptake ______ in direct proportions because the body requires more oxygen to perform at higher intenisties
- 18. The state in which oxygen supply equals oxygen demand
- 20. This can provide energy for ATP resynthesis under both anaerobic and aerobic conditions
- 22. The ATP PC system is used during _____ durations
- 23. The ATP PC system has a _____ intensity
- 25. The slowest energy system to contribute towards ATP resynthesis due to the complex nature of its chemical reactions
- 26. The elevated oxygen consumption which exceeds that normally experienced at rest, is referred to as…
- 28. The aerobic system has a ___ intensity
- 29. Increased motor unit and muscle fibre recruitment, AVO2 difference, muscle temperature, muscle enzyme activity, oxygen use and decreased muscle substrates are a result of which acute response system
- 31. The aerobic energy system provides energy for activities that require low-moderate intensities over _____ ______ e.g marathon
Down
- 1. In which energy system are muscular stores of glycogen converted into glucose, then, with the aid of glycolysis enzymes the glucose is broken Dow into a substance called pyruvic acid
- 2. Refers to the processes being involved in the breakdown of stored phosphagens (ATP AND PC) without oxygen being involved
- 5. When this bond is broken, energy is released that enables ATP to be resynthesised from ADP and Pi (used for short duration, high intensity efforts)
- 7. The state in which there is a discrepancy between oxygen supply and the oxygen needed to meet the energy requirements of the activity
- 8. Essential component of a balanced diet. Allows for muscle growth and repair, fights diseases, assist in chemical reactions and transport materials
- 12. Increased HR, SV, Q, blood pressure, AVO2 difference and redistribution of blood flow to working muscles are a result of which acute response system
- 14. The ATP PC system provides energy for activities that require _____ efforts
- 15. Which recovery type is used to restore ATP and PC stores (ATP PC system)
- 16. Increased RR, TV, V and pulmonary diffusion are a result of which acute response system
- 17. Acute responses to the respiratory system to exercise are designated to facilitate an increase in the availability of oxygen and the removal of _____ ______
- 19. The anaerobic glycolysis system provides energy for activities that require high intensity with ______ rest
- 21. Cardiovascular acute responses are designated to facilitate rapid and efficient delivery of increased amounts of _____ to the working muscles in order to meet the body’s increased demand for energy
- 24. The anaerobic glycolysis system has a ____ intensity
- 27. Which recovery type is used to help the body to recover from exercise where the aerobic or anaerobic glycolysis systems have been the primary contributors to ATP resynthesis
- 30. The final point where lactate entry into and removal from blood are balanced (Aerobic power)
