Across
  1. 3. glucose stored in the body. Used for fuel when blood glucose levels decline
  2. 5. principle that implies that greatest gains occur when training resembles competition movement
  3. 7. training that incorporates high intensity work with limited recovery
  4. 9. number of heartbeats/minute while at rest
  5. 10. generally is the use of free weights to lengthen and then contract muscle fibres
  6. 11. apply resistance without changing muscle length
  7. 12. ability of a muscle or muscle group to exert a force against a resistance
  8. 14. point at which lactic acid accumulates rapidly in the blood
  9. 15. implies that gains in fitness occur when training load is increased as improvements occur
  10. 17. growth
  11. 18. in the presence of oxygen
  12. 20. amount of blood ejected by the left ventricle during a contraction
  13. 21. ability of working muscles to use the oxygen being delivered
  14. 23. range through which joints and body parts are able to move
Down
  1. 1. in the absence of oxygen
  2. 2. process of restoring ATP to its former state
  3. 4. by product of the incomplete breakdown of CHO in the absence of oxygen
  4. 6. the amount of air the lungs can hold
  5. 7. process of breaking down glucose in the absence of oxygen to produce energy
  6. 8. the lowest level at which we can train and still make some fitness gains
  7. 13. referred to as the "detraining effect"
  8. 16. training that uses the aerobic energy system as the main source of energy
  9. 19. measures the energy value of food
  10. 22. refers to wasting or a decrease in size
