Question

The force of a muscle contraction is higher when the muscle is stimulated every 0.5 secs than when stimulated with the same voltage every 0.05 seconds.
a. True
b. False

Answer 1

Answer:

b. False

Explanation:

Increasing the frequency of muscle stimulation causes wave summation to occur, which causes an overlap of muscle twitch. When this muscle summation happens, the force generated in the muscle increases. This means that stimulating the muscle every 0.5 seconds will generate less muscle contraction force than when stimulated every 0.05 seconds
