Across
  1. 5. A muscle found in only the heart.
  2. 10. a mineral essential for bone growth. Can be found in a variety of foods like milk,cheese,yoghurt and more.
  3. 11. exhaustion of muscle from prolonged exertion or over stimulated.
  4. 13. contractions generate force by changing the length of the muscles, different contractions give different forces.
  5. 15. An increase in the diameter of blood vessels.
  6. 18. known as “slow twitch oxidative” they are used in lower intensity exercises like light resistance work and long distance aerobic activities e.g. 5k and 10k runs
  7. 19. An organic compound and hydrotrope that provides energy to drive many processes in living cells. E.g. muscle contraction.
  8. 20. This is the internal framework of the human body. Including bones, muscles, cartilage and others.
  9. 23. study the ways the body responds to exercise and training
  10. 24. A strong fibrous tissue that attaches muscle to bone.
  11. 25. a muscle cell that makes skeletal muscles.
  12. 26. a reduction in the diameter of blood vessels.
  13. 27. a protein based building tissue used to repair tissues. It also provides strength and cushioning for body parts.
  14. 28. specialised bone cells that build new bone tissue
  15. 29. diarthroses are free joints e.g. ball and socket joint, hinge joint. Synovial fluid helps lubricate and cushion the joint.
  16. 30. The movement of blood through vessels from arteries to capillaries then into veins.
Down
  1. 1. the contraction time is the phase of relaxation and the muscle to return to its normal length
  2. 2. A short band of tough and fibrous flexible tissue that holds bones together.
  3. 3. this is another type of twitch fibre and is faster and more powerful then type iia. They are inefficient and fatiguing quickly as they are used for very short activities that require significant power and strength.
  4. 4. a very small tear or rip e.g. tendons.
  5. 6. a source of glucose used for fuelling activity.
  6. 7. this is the temperature of your muscles, for example when working out the muscle temperature increases.
  7. 8. a bunch of minute blood vessels that form networks throughout bodily tissues, so the capillaries can exchange oxygen and nutrients for wastes in the blood and tissue.
  8. 9. The enlargement of an organ or tissue caused by an increase in the reproduction rate of its cells. Often the initial stage of cancer.
  9. 12. A level of training intensity where the athlete approaches maximum heart rate and performs exercise to an increasingly anaerobic level.
  10. 14. How thick a fluid is, affecting its resistance to flow.
  11. 16. A lifelong process where mature bone tissue is removed from the skeleton and new bone tissue is formed
  12. 17. known as “intermediate muscle fibres, they’re a mix of type I and IIa. they can use both anaerobic and aerobic energy systems. They have higher oxidative capacity and fatigue slowly.
  13. 21. large nucleated cells that destroy bone cells, reabsorb calcium and play a major role in bone remodelling.
  14. 22. a medical condition that weakens bones due to a lack of calcium stored. The bones are fragile, brittle and easy to break.
