Question

Which muscle are
less prone to fatigue​

Answer 1

Answer:

Although skeletal and cardiac muscle are similar in many ways, there are important physiological differences that make cardiac muscle much less prone to fatigue. As you point out in your question, the build-up of lactic acid plays a major role in muscle fatigue.

Explanation:

Answer 2

• The production of skeletal muscle force depends on contractile mechanisms, and failure at any of the sites upstream of the cross-bridges can contribute to the development of muscle fatigue, including nervous, ion, vascular and energy systems.
