Following tetanizing stimulus was to a muscle, there is a constant contraction. This is due to
Tetanization: as the frequency of the stimulus increases to a critical level the successive contractions become so rapid that whole muscle contraction becomes smooth and contineous This is called tetanization and frequency is tetanizing frequency Ref:Guyton and Hall textbook of medical physiology 12th edition,page number:97
Recruitment phenomenon
At high stimulus frequency all muscle fibers are contacting
Contraction of different muscle fibers at different places
All of the above
