With eccentric muscle contractions:

Question

Quizplus · Accepted Answer

Eccentric muscle contractions occur when the muscle is lengthening while contracting. As the muscle lengthens, tension is developed within the muscle. So, option B is the correct answer. Option A is incorrect because tension does increase during an eccentric contraction. Option C is incorrect because concentric contractions involve muscle shortening, not eccentric contractions. Option D is incorrect because muscle length and tension do vary during an eccentric contraction, but the correct answer is that the muscle is lengthening while contracting.
