Question

PhysioEx 9.1 Exercise 2: Skeletal Muscle Physiology, Activity 3: The Effect of Stimulation Frequency on Skeletal Muscle Contraction (3).

The figure below is from PhysioEx Exercise 2: Skeletal Muscle Physiology, Activity 3: The Effect of Stimulation Frequency on Skeletal Muscle Contraction.

Note in this graph, the tension (force) will rise then fall to zero as stimuli is delivered relatively close together.

A- Summation B- A single muscle twitch C- Incomplete tetanus D- Treppe E- Complete tetanus -Plateau Stimuli Time (msec)

Explanation / Answer

The given figure explains the Treppe which defines the gradual increase in the muscle contraction following the repeated stimuli.
