Closed chain movements are characterized by which of the following?

Closed chain movements are characterized by which of the following?

• A. refers to a position where the most DISTAL aspects of a given extremity are FIXED to the earth or another solid object. This fixed position alters the movement of the joints & surrounding musculature up the chain. (f.e. squat)
• B. Open chain movement where distal end moves freely
• C. Midline stabilization
• D. Relative intensity

Answer: (A)

Closed-chain movements have the distal segment fixed to the ground or a solid object, so the limb cannot move freely at its far end. This setup forces forces to travel through multiple joints and the surrounding muscles in a coordinated pattern, often with the body stabilizing through the trunk as you move. A squat is a clear example: the feet stay planted, the ankle, knee, and hip joints move in concert, and the core helps stabilize the movement. This is different from open-chain movements, where the far end moves freely, like a leg extension or a bicep curl. The other options don’t define the pattern of fixed distal segments and multi-joint coordination that characterizes closed-chain work.
