Final answer:

The statement is true as the agonist's muscle typically contracts concentrically while the antagonist's muscle acts eccentrically during controlled movements such as lifting and lowering weight.

Step-by-step explanation:

The statement that during a movement, the agonist muscle will be in concentric muscle action and the antagonist muscle will be in eccentric muscle action is generally true. When performing a movement such as lifting a hand weight, the biceps brachii, in this case, the agonist, contracts concentrically as the muscle fibers shorten and bring the forearm towards the body. Conversely, when lowering the hand weight, the biceps brachii now demonstrate an eccentric contraction where the muscle lengthens while still maintaining tension to control the lowering of the weight.
