o 10-5 Students can describe the mechanism responsible for tension production in a muscle fiber, and compare the different types of muscle contraction
o 10-6 Students can describe the mechanisms by which muscle fibers obtain the energy to power contractions.
o 10-7 Students can relate the types of muscle fibers to muscle performance, and distinguish between aerobic and anaerobic endurance.

Checkpoints
10-5
Draw and label a picture of a motor unit?
Using your picture show/describe how motor units, recruitment, and muscle tone are related.
Draw pictures to represent the 3 mechanisms used to return muscle to resting length.
10-6
Draw a diagram comparing and contrasting aerobic metabolism and anaerobic glycolysis.
Relate/show energy use and the level of muscular activity to the diagram in the previous questions.
What is produced at peak levels of muscular activity? Label where this occurs on your diagram.
List the various causes of muscle fatigue.
Relate muscle fatigue, oxygen debt (EPOC), and the recovery period.
List and describe what ways hormones play a role in skeletal muscle?
10-7
Make a diagram (chart, picture, etc.) comparing and contrasting between force and endurance. In the diagram be sure to include the following:

10-7
Make a diagram (chart, picture, etc.) comparing and contrasting between force and endurance. In the diagram be sure to include the following:
- Three types of skeletal muscle fibers.
- White muscle and red muscle.
- Anaerobic and aerobic endurance.
- Indicate where hypertrophy and atrophy would occur in relation to your diagram.
