Closed kinetic chain exercise is characterized by?

• A. Distal segment moves freely
• B. Movement occurs at multiple joints
• C. Usually non-weight bearing
• D. Distal segment fixed to surface

Answer: (C)

In closed kinetic chain exercises, the end of the limb that contacts the environment is fixed to a surface, so weight is borne through the limb. Because that distal segment is anchored, movement occurs across multiple joints as the body system coordinates to complete the movement. This fixed-end, weight-bearing setup is what defines CKC tasks like squats, push-ups, or standing leg presses, where the foot or hand stays in contact with the surface while the rest of the limb moves.

This differs from open kinetic chain actions, where the distal segment moves freely and is typically non-weight bearing, such as a leg extension or bicep curl. The idea that CKC exercises are usually non-weight bearing isn’t correct because CKC relies on a stable distal contact point and loading through the limb.
