18. D-100
QUESTION: Single, brief muscle contraction because of a lack of nerve stimulation is called:
ANSWER: son of a “twitch”

19. D-200
QUESTION: During a muscle contraction, the initial energy used is ATP stored in the muscle. About how long will this last?
ANSWER: 4 to 6 seconds

20. D-300

ANSWER: fused or complete tetanus

21. D-400
QUESTION: During muscle contraction a graded response can be changed by which two things?
ANSWER: The amount of muscle fibers stimulated and the frequency in which they are stimulated.

22. D-500
QUESTION: If you ran the 200 meter dash in 24 seconds, most of your energy would come from which system?
ANSWER: creatine – phosphate or Direct phosphorylation

23. E-100 QUESTION: What is an isometric muscle contraction
Answer: contraction of a muscle without shortening

24. E-200
QUESTION: If you rode a bike for one hour and 30 minutes straight , at a steady pace, which energy system would you be using the most?
Answer: Aerobic respiration

25. E-300
QUESTION: If you do a weight workout and then run some sprints after, which energy system would you be using the most?
Answer: anaerobic glycolosis

26. E-400
QUESTION: Explain what the origin and insertion are in dealing with muscle attachment to bones
Answer: Origin – immoveable bone
Insertion – moveable bone

27. E-500
QUESTION: Why is it important to incorporate both aerobic and anaerobic exercise into your life? Give 3 reasons why for both types of exercise.
Answer: Results in stronger more flexible muscles with greater resistance to fatigue
Changes are due to an increase in blood supply to muscles so muscle cells form more mitochondria to store more oxygen
Important secondary benefits:
1) makes overall body metabolism more efficient
2) Improves digestion and elimination
3) enhances neuromuscular coordination
4) makes skeletal muscles stronger (to some extent)
5) Heart enlarges to pump more blood (more efficient)
6) Fat deposits are cleared from artery walls
7) lungs become more effiecient in gas exchange
Weightlifting / Resistance Training
Increases the size of the muscle; also increases the definition and tone of the muscles.
Women don’t need to worry about getting “too bulky”
Increases the strength of the muscle which can be a benefit in many jobs or daily routines.
Increase in size and strength is due mainly to enlargement of the individual muscle cells; there is also an increase in the connective tissue around muscle and fibers.

28. FINAL JEOPARDY Topic – Sliding Filament Theory of muscle contraction!
Question: Write out as much as you can remember about the sliding filament theory of muscle contraction.
The group with the most words underlined (by me) will be the weiner
