Match the following:
A) Treppe B) Maximal stimulus C) Multiple motor unit summation D) Tetanus E) Wave summation 1) The stimulus above which no stronger contraction can be elicited, because all motor units are firing in the muscle. 2) The phenomenon in which the contraction strength of a muscle increases, due to increased Ca2+ availability and enzyme efficiency during the warm-up. 3) Continued sustained smooth contraction due to rapid stimulation. 4) The situation in which contractions become stronger due to stimulation before complete relaxation occurs. 5) How a smooth increase in muscle force is produced.
Tetanus occurs when a muscle fiber is stimulated so rapidly that it is not allowed to relax between stimulations, resulting in a smooth, sustained contraction
