Stimulus frequency-
how often stimulus applied
(rate of delivery) Describe the force of contraction with each subsequent stimulus.
What is the effect of increased frequency of stimulation on the strength of contraction?
By increasing the frequency of stimulation
will increase the tension developed
. It is not allowing enough time for the calcium to be sequestered back up. Describe a normal muscle muscle contraction? Muscle contractions are usually smooth and not jerky like a twitch.
What is the difference between stimulus intensity and stimulus frequency?
1. What is the difference between stimulus intensity and stimulus frequency? The stimulus intensity is the
electrical changes that relate to the action potential
. The Page 2 Copyright © 2014 Pearson Education, Inc. frequency is the number of action potentials per minute.
What was the effect of increasing the frequency of stimulation?
On the other hand, at increasing frequency of stimulation the influence of
the initial low-frequency stimulation can depress the tension-time area
. The decreasing rate of stimulation during relaxation appeared to support the tension more effectively in slow-twitch motor units than in fast ones.
Which of the following is true of the maximum stimulus frequency?
Which of the following is true of the maximum stimulus frequency?
No greater muscle force can be generated and the muscle has reached maximal tetanic tension
.
Will changes to the stimulus voltage?
No
, changing the stimulus voltage will not change the latent period duration. … As the stimulus voltage is increased from 1.0 volt up to 10 volts, what will happen to the amount of active force generated with each stimulus?
What is the relationship between stimulus frequency and muscle force?
The force–frequency relationship presents the
amount of force a muscle can produce as a function of the frequency of activation
. During repetitive muscular contractions, fatigue and potentiation may both impact the resultant contractile response.
Why does increasing stimulus strength affect twitch force?
Question: Why does varying the stimulus strength affect the twitch force? Answer:
With stronger stimuli, more nerve fibers are stimulated and therefore more motor units are recruited
.
Why does the amplitude of the muscle response increased with increasing stimulus voltage?
As noted in Figure 1 and Table 1 the amplitude of the muscle response increases with increasing stimulus voltages. This is so because
more and more of the muscle mass is stimulated as the voltages increase
. At high stimulus voltages, the muscle response reaches maximum amplitude.
What is intensity of stimulus?
Rather, as stimulus intensity is increased,
the probability that an observer will say that the stimulus is visible increases
. This relationship between the probability of a response and the stimulus intensity is called a psychometric function.
When the stimulus frequency reaches a value beyond which?
When the stimulus frequency reaches a value beyond which no further increases in force are generated by the muscle, the muscle has reached its You correctly answered: a.
maximal tetanic tension
…. show more content… 1.
Does the force generated change with each stimulus?
Your answer: As the
stimulus frequency increases
, the muscle force generated by each successive stimulus will increase.
What happens to force production with each subsequent stimulus?
What happens to force production with each subsequent stimulus?
Force increases with each subsequent stimulus
.
When stimulus frequency is increased but some relaxation still occurs this is called?
Complete tetanus, also called fused tetanus
, occurs when the frequency of stimuli increases still further (refer to Figure 1d). In this case, individual muscle contractions completely fuse to produce one large muscle contraction.
What has happened in the muscle when maximal stimulus is achieved?
During initial stages of contraction, what happens to force production over time? define the term maximal stimulus? What has happened in the muscle when the maximal stimulus is achieved? …
Recruitment is achieved by higher force of stimulation
.
Which state of stretch of muscles produces the strongest contraction?
Muscles are stronger in
eccentric contractions
than in isometric and concentric contractions.
