Question

Quizplus · Accepted Answer

Concentric and eccentric contractions are both subtypes of isotonic contractions, which involve changes in muscle length while maintaining a constant load or tension. Isometric contractions, on the other hand, involve maintaining a constant muscle length while generating tension against an immovable object. Elastic contractions also refer to a different mechanism altogether, involving the stretching and subsequent release of elastic tissues like tendons.
