Question

a static muscle action is:
concentric
eccentric
isotonic
isometric
question 5 1 pts
which of the following statements about concentric muscle action is false:
the muscle shortens as it goes through the range of motion.
the arm curl is a good example.
the muscle is able to overcome the load.
it is usually termed extension.
question 6 1 pts
dynamic contraction occurs whenever the force generated by the muscle contraction results in movement.
true
false

Explanation:

• For the first question, isometric muscle action is static as there is no change in muscle length. Concentric, eccentric, and isotonic involve muscle - length changes.
• For the second question, concentric muscle action is muscle shortening, arm curl is an example, and the muscle overcomes the load. It is not extension.
• For the third question, dynamic contraction occurs when muscle - generated force causes movement.

Answer:

• Question 5: D. isometric
• Question 6: D. It is usually termed extension.
• Question 7: True
