QUESTION
When a muscle is stimulated with rapidly succeeding stimuli (20/sec) the result response is?
OPTIONS
(A) Tetanus
(B) Treppe
(C) Recruitment
(D) Fatigue
ANSWER
(B) Treppe
EXPLANATION
Treppe is the correct option because rapidly repeated submaximal stimuli can produce a staircase-like progressive increase in muscle contraction strength known as treppe, particularly during the initial responses. Tetanus is a sustained contraction produced by sufficiently high-frequency stimulation, recruitment refers to activation of additional motor units, and fatigue is a decline in force.
