MUSCLE PHYSIOLOGY

Detailed explanation-1: -Isotonic contractions maintain constant tension in the muscle as the muscle changes length.

Detailed explanation-2: -Isotonic contractions are those in which there is consistent tension as the muscle length changes. These can be either concentric (muscle shortening) or eccentric (muscle elongation). Isometric contractions are those in which the length of the muscle does not change.

Detailed explanation-3: -Key Terms. Isometric: A muscular contraction in which the length of the muscle does not change. isotonic: A muscular contraction in which the length of the muscle changes. eccentric: An isotonic contraction where the muscle lengthens. concentric: An isotonic contraction where the muscle shortens.
