How does training affect performance?

2. by product of the incomplete breakdown of CHO in the absence of oxygen
4. generally is the use of free weights to lengthen and then contract muscle fibres
6. number of heartbeats/minute while at rest
8. process of restoring ATP to its former state
10. in the absence of oxygen
11. ability of working muscles to use the oxygen being delivered
13. the lowest level at which we can train and still make some fitness gains
16. the amount of air the lungs can hold
17. referred to as the "detraining effect"
18. apply resistance without changing muscle length
20. range through which joints and body parts are able to move
21. process of breaking down glucose to produce energy
22. implies that gains in fitness occur when training load is progressively increased as improvements occur

1. point at which lactic acid accumulates rapidly in the blood
3. training that incorporates high intensity work with limited recovery
5. in the presence of oxygen
7. ability of a muscle or muscle group to exert a force against a resistance
9. amount of blood ejected by the left ventricle during a contraction
12. measures the energy value of food
14. training that uses the aerobic energy system as the main source of energy
15. principle that implies that greatest gains occur when training resembles competition movement
19. glucose stored in the body. Used for fuel when blood glucose levels decline
