Most Muscle Work is Accomplished by ________

Question

Most muscle work is accomplished by ________.
A) treppe
B) incomplete tetanus
C) wave summation
D) complete tetanus

Accepted Answer

The most efficient muscle work is accomplished by complete tetanus, where the muscle contracts with maximum force and sustains the contraction. In incomplete tetanus, muscle fibers are stimulated before they can relax, which produces a greater force of contraction but is less sustainable over time. Treppe occurs when muscle fibers are stimulated at a low rate, causing each contraction to be slightly stronger than the previous one. Wave summation results from stimuli being delivered at a higher frequency, causing each contraction to be stronger than the previous one, but not as strong as the sustained contraction of complete tetanus.
