PhysioEx 8.0 -- Skeletal Muscle Simulation Act. 6 & 7

6. Turning the stimulator off allows a small measure of recovery. The muscle will produce force for a longer period if the stimulator is briefly turned off than if the stimulations were allowed to continue without interruption, Explain.

When the stimulator is turned off the muscle is able to “catch up” a little with ATP production.

7. Describe the difference between thecurrent tracing and the myogram generated in step 6.

The second tracing shows faster fatigue than the tracing in which the stimulator was turned on and off.

Activity 6
Explain what must happen to the intensity and frequency of the stimulus to achieve smooth contraction at different force levels.

Increasing the stimulation rate causes smoother force production and decreasing the velocity decreases the total force produced. With manipulating both allows the muscle to produce smooth force at any level.

Activity 7

Turning the stimulator off allows a small measure of recovery. The muscle will produce force for a longer period if the stimulator is briefly turned off than if the stimulations were allowed to continue without interruption. Explain why.

The muscle then can catch up with ATP production.

Describe the difference between the current tracing and the myogram generated in step 6.

The second tracing shows faster fatigue than the tracing with the stimulator turned on and off.

^ + for you missy25

For activity 6 and 7, I have:

6. When the stimulator is turned off the muscle is able to “catch up” a little with ATP production.

7. The second tracing shows faster fatigue than the tracing in which the stimulator was turned on and off.
