How does threshold stimulus affect Twitch contraction force?
There are 15 pulses (stimuli) per second. See Graph: Effect of Stimulation Value on Twitch Contraction Force 1. What is the threshold stimulus? 400mV. 2. What is the maximum force generated at the threshold stimulus? The maximum force generated was 0.084 gf. 3. How does increasing voltage above threshold stimulus affect force development?
When does depolarization cause a contraction what happens?
This minimal voltage is called a threshold stimulus. Once the depolarization reaches the threshold stimulus, the muscle fiber or the nerve will generate an action potential, and will cause a contraction. As the stimulus voltage is increased past the muscle’s threshold voltage, an increase in the amount of force in the entire muscle can be observed.
When does the force of contraction increase or decrease?
As muscle fiber length increases: contraction force increases, becoming maximum at an optimal length, then decreasing at longer lengths. 2. As the frequency of stimulation increases, the force of contraction: increases.
Which is greater muscle tension or single twitch?
The tension produced during a sustained contraction is greater than that produced by a single twitch. The more stimuli per second, the greater the force generated by the muscle due to a sustained contraction. Muscle tension depends on the frequency of stimulation of motor units and the number of motor units stimulated.
