Which phase of motion is characterized by resisting gravity?

• A. Concentric
• B. Eccentric
• C. Isometric
• D. Dynamic

Answer: (B)

The phase of motion characterized by resisting gravity is the eccentric phase. In eccentric movement, the muscle lengthens under tension while controlling the descent of the weight or resistance. This is often where the muscle works to resist the pull of gravity, such as when lowering a weight back to the ground after lifting it. During this phase, the muscles must generate enough force to slow down the gravitational pull and prevent a sudden drop, contributing to strength building and muscle control. In contrast, the concentric phase involves muscles actively shortening while pushing against gravity (like lifting a weight), and the isometric phase refers to muscles maintaining a constant length without movement, often used during stabilization. Dynamic movement encompasses various types of movements but does not specifically define the interplay with gravity. Thus, the unique action of resisting gravity is distinctly associated with the eccentric phase of motion.
