Summary

Action potentials in response to rhythmic stimulation of the motor nerve were registered from the quickly and slowly contracting cat's muscles. Slow muscles take a much longer time to reach the maximal amplitude of the spikes, counting from the commencement of the stimulation, and are characterized by a much greater stability of the amplitude in prolonged stimulation. The nerve fibers innervating the slow muscles are, in the majority of case, the less exitable ones. In indirect stimulation, slow muscles begin to transform the rhythm at a lower frequency of stimulation than the quick ones. These muscles are capable of maintaining the transformed rhythm for a long time. Quick muscles, producing a higher rhythm without its transformation, lose their ability to respond to frequent stimulations very rapidly (in fractions of a seond).
