Question

Muscle length doesn't change in:
Isotonic contraction
Isometric contraction
Tetanic contraction

Answer 1

Answer:

Tetanic contraction is the answer

Answer 2

An isotonic concentric contraction results in the muscle shortening, an isotonic eccentric contraction results in the muscle lengthening. During an isometric contraction the muscle is under tension but neither shortens nor lengthens.
