Question

6. Which of the following statements is true?

A. Isotonic contractions cause the muscle to change its shape while the tension remains constant.
B. Isotonic contractions cause the tension to increase without a change in shape.
C. Isometric contractions cause the muscle to change its shape while the tension remains constant.
D. Isometric contractions increase the tension and change the shape of the muscle.

Answer 1

Final answer: A

Explanation: I believe it is A. In isotonic contractions the shape of the muscle changes in length and the tension is constant, therefore it would be A and not B. This is because b states that the tension increase (but it remains constant) and that there is no change in shape (but the muscle lengthens).
