Across
  1. 4. is the energy source for all muscular effort
  2. 6. is a thin filament that attaches to the Z line
  3. 8. where both actin and myosin are found. It equates with the length of the myosin filaments
  4. 10. is released as a by-product of physical exertion
  5. 12. muscles where the origin (the attachment to a fixed bone, usually the proximal attachment) is wider than the point of insertion
  6. 13. is a thick filament situated between each of the actin filaments
  7. 17. capacity of an individual's body to transport and utilise oxygen
  8. 18. the portion of oxygen required to remove lactic acid from the muscle cells and blood
  9. 19. is the state in which oxygen supply equals oxygen demand
  10. 22. ___________ Each muscle fibre is made up of long strands called
  11. 23. the capacity in which an individual can perform activities without utilising oxygen
  12. 24. ____________continue to detach and reattach themselves from the actin filaments, shortening the sarcomere
  13. 25. ________ is the amount of oxygen consumed during the recovery period
  14. 26. the portion of oxygen required to synthesise and restore muscle phosphagen stores (ATP and PC)
Down
  1. 1. is taken into the body via the respiratory system
  2. 2. _________ is broken down, producing ATP and energy for muscular contraction.
  3. 3. Fascicles are short and they attach obliquely to a central tendon
  4. 4. an immediate response to an exercise session
  5. 5. muscles where the origin (the attachment to a fixed bone, usually the proximal attachment) is wider than the point of insertion
  6. 7. where only actin is found
  7. 9. a long term response or adaptation to a number of exercise sessions, constituting a training program
  8. 11. A decreased capacity to perform a maximum voluntary muscle action or a series of repetitive muscle actions
  9. 14. responsible for contracting the muscle
  10. 15. Aerobically trained muscle also has a greater capacity to process ___________ for fuel
  11. 16. Oxygen uptake ____________ linearly, or in proportion to increases in heart rate and exercise intensity
  12. 20. is the state in which there is a discrepancy (shortfall) between oxygen supply and demand and the oxygen needed to meet the energy requirements of the activity.
  13. 21. where only myosin is found
  14. 24. Oxygen is distributed to muscles by the __________ system
