Question

A shortening of the muscle that occurs when the tension is greater than the load is a(n) ________?

1) Isometric contraction
2) Eccentric contraction
3) Concentric contraction
4) Isotonic contraction

Answer 1

A 3) concentric contraction is a shortening of the muscle that occurs when the tension is greater than the load. Example: biceps brachii muscle contracting to bring a hand weight upward.

Step-by-step explanation:

Isotonic contractions occur when the tension in the muscle stays constant and the length of the muscle changes. In this case, the correct answer is option 3) Concentric contraction. A concentric contraction is a shortening of the muscle that occurs when the tension generated by the muscle is greater than the load it is moving. An example of a concentric contraction is when the biceps brachii muscle contracts to bring a hand weight upward with increasing muscle tension.
