Unit 3 AOS 2: Energy systems
Across
- 4. A chemical fuel source
- 5. refers to the moment then the body can just prevent the accumulation of hydrogen ions in the working muscles
- 6. Energy system that produces lactic acid
- 8. When cells need energy, it breaks the bond between the second and third phosphate. This forms ADP and __________
- 11. When an athlete delays carbohydrates becoming the predominant fuel source during endurance events
- 12. A training method to develop the ATP-PC system
- 13. At the end of exercise when the demand for ATP decreases and oxygen consumption is still high
- 15. Butter, margarine, cheese, fatty meats
- 16. When oxygen supply meets oxygen demand
- 18. Lean meat, fish, eggs. Stored as muscle at various body sights
Down
- 1. At the start of exercises when oxygen supply fails to meet the body's demand
- 2. Which system has an increase in Venous returns as an acute response to exercise
- 3. Which system has an increase in blood flow to working muscles as an acute response to exercise
- 6. Dominant energy system used for events 0-10 seconds
- 7. Which system has an increase in ventilation as an acute response to exercise
- 9. Stored as glycogen at the muscle and liver
- 10. immediate physiological responses to exercise
- 14. All three energy systems work together to provide energy
- 17. Dominant energy system used at rest and submaximal intensity
