Answer :
Final answer:
Treppe is the gradual increase in muscle contraction force with repeated stimulation, resembling a set of stairs, making contractions more efficient.
Explanation:
Treppe is the progressive increase in muscle contraction force that occurs with repeated stimulation at a constant frequency. This phenomenon results in the muscle tension increasing in a graded manner that looks like a set of stairs, making muscle contractions more efficient. It is believed to be influenced by a higher concentration of Ca ions in the sarcoplasm due to continuous signaling from the motor neuron.
