Isometric contraction occurs when the muscle length does not change, but the tension within the muscle increases. This type of contraction is useful for maintaining posture and holding objects in place. Isotonic contraction, on the other hand, involves a change in muscle length, and can be further classified as concentric (the muscle shortens while contracting) or eccentric (the muscle lengthens while contracting). Motor contraction and hypertonic are not valid terms in the context of muscle contraction.
