Quizplus · Accepted Answer

Eccentric contractions occur when the muscle lengthens while producing tension, and research has shown that they are more efficient than concentric contractions in terms of energy expenditure. Isometric contractions involve holding a muscle at a constant length, while isotonic contractions involve maintaining a constant tension while the muscle changes length. Both of these types of contractions are less efficient than eccentric contractions.
