2. The highest point working aerobically where lactate production and removal are equal
4. Our bodies ability to regulate our body temperature
9. Has the by-products CO2, heat and water
10. The blood vessels narrow to limit blood flow
11. Produces ATP anaerobically
14. Often referred to 'hitting the wall'
15. No oxygen required
18. The body's ability to tolerate the accumulation of hydrogen ions

1. Lactate + Hydrogen molecules
3. Fastest way to oxidise the fatiguing by-products and return to pre-exercise body tempterature
5. How quick ATP can be delivered
6. All three systems working together to produce ATP
7. Deplete after 10-15seconds of high intensity work
8. Allows for PC stores to replenish
10. The blood vessels open to let more blood through
11. Produces ATP at an explosive rate
12. The lag time before oxygen reaches the muscle cells
13. Term to describe molecule breakdown to resynthesis ATP
16. A term to describe the blood becoming 'thick'
17. Carbohydrate storage molecule
