Hyperextension is best described as?

Hyperextension refers to an extension movement that exceeds the normal range of motion, going beyond the anatomical position of the body. In this context, the anatomical position is considered as the standard reference where the body is upright, facing forward, with arms at the sides and palms facing forward.

When hyperextension occurs, it typically involves the straightening of a joint to a degree that is beyond what is considered typical range, resulting in an increased angle between adjoining body segments. This can often lead to strain or injury if the movement exceeds the natural limits of the joint.

The other concepts mentioned do not accurately capture the essence of hyperextension: bending movements decrease the angle between body parts rather than increasing it, rotation refers to turning a body part around an axis, and sideways movement of limbs does not pertain to the extension or flexion of joints, making those definitions less relevant in describing hyperextension.
