Question

sustained contraction that results in max tension of the muscle fibers is called?
summation
muscle fatigue
tetanus
latency

Explanation:

To solve this, we analyze each option:

• Summation: Involves adding muscle contractions but not max sustained tension.
• Muscle fatigue: Results from prolonged activity, not the sustained contraction with max tension.
• Tetanus: Is a sustained muscle contraction that achieves maximum tension in muscle fibers.
• Latency: Refers to the time delay in a response, not related to muscle contraction tension.

Answer:

C. tetanus
