Activity 9:  Isotonic Contractions

3.   You can observe from the trace that the muscle is rising in force before it reaches the plateau phase.  Why doesn’t the muscle shorten prior to the plateau phase?

7.   What happened when you attached the 2.0 gram weight to the muscle and stimulated the muscle?  How did this trace differ from the other traces?  What kind of contraction did you observe?

Please help me ! Thank you!

Exercise 2: Skeletal Muscle Physiology Worksheet
Jun 24, 2011

Hey!

Activity 9

5. During the flat part of the tracing, the muscle rises from the surface of the platform and then descends again.
The force production does not change during the flat part of the (the tracing is flat!); it stays the same.

6. 1.5g | 0.45 mm/sec
7. 1.0g | 1.34 mm/sec
2.0g | 0.00 mm/sec

9. the resistance (weight), the shorter the initial velocity of shortening.

15. As the starting length of the muscle is increased from 60 mm to 90 mm, the initial velocity of shortening first increases (to a muscle length of 75 mm) and then decreases.
