  1. 3. This system mainly provides the bulk of ATP production during high intensity, sub-maximal efforts
  2. 6. Every sarcomere along the muscle fibre shortens, leading the whole muscle to
  3. 7. provides the major source of energy for long-term physical activity
  4. 8. The human body requires a supply of energy both to meet the needs of its systems and organs and to power muscular contraction for movement.
  5. 10. The capability to generate activity, to produce or do work
  6. 12. They are also known as white (much paler as they contain little myoglobin)
  7. 14. These muscles are a compromise between fusiform and pennate muscles because they are capable of producing strength and power while retaining their mobility
  8. 17. One of the main arrangements of major skeletal muscles used in physical activity include
  9. 19. a contractile unit, and each one is designated by a line at either end called a Z line
  10. 20. contraction is the most common type of muscular contraction. During this contraction, the muscle shortens, causing movement at the joint

  1. 1. The aerobic system is the predominant system for use during extended __________ events such as marathons and low demand activities such as walking, sitting and reading
  2. 2. only minimally contributes to ATP production
  3. 4. They are also known as red (due to the presence of myoglobin) and Type I fibres
  4. 5. When digested, it is broken down to glucose for blood transportation and then stored as glycogen in the muscles and liver
  5. 9. the fascicles are short and they attach obliquely to a central tendon that runs the length of the muscle
  6. 11. Skeletal muscle is covered with a layer of connective tissue called
  7. 13. contraction is a form of static contraction where length is unchanged despite application of tension
  8. 15. High energy compound that stores and transfers energy to body cells
  9. 16. energy-rich compound that serves as an alternative energy source for muscular contraction
  10. 17. all skeletal muscle is made up of
  11. 18. contraction occurs when the muscle lengthens while under tension. The action often happens with the assistance of gravity
