Question

Difference between isotonic and isometric muscle contractions

Answer 1

In summary, skeletal muscle contractions are either isometric, in which the muscle does not change its length, or isotonic, in which the muscle changes its length without increasing tension. ... Once the load is exceeded, contraction can then be used to shorten the muscle and move the load.

Answer 2

Answer:

In an isotonic contraction, the muscle maintains the same tension as it shortens, however, in an isometric contraction, the muscle remains the same length as the tension changes.
