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!

17.explain the relationship between the amount fo resistance and the intial velocity of shortening.
18. explain why it will take you longer to perform 10 repetitions lifting a 20-pound weight than it would to perform the sam number of repetitions with a 5-pound weight.

Thank You!
