What movement type refers to a turning motion around the long central axis of a segment?

The movement type that refers to a turning motion around the long central axis of a segment is known as pivoting. This involves rotation around a central point or axis, allowing for circular movement in a controlled manner. In the context of human movement, pivoting can occur in various body parts, such as the forearm (rotating the radius around the ulna) or the trunk (rotation of the torso). This type of movement is essential in many sports and activities where agility and quick directional changes are required.

Flexion and extension relate to the bending and straightening of joints, while adduction involves moving a limb toward the midline of the body. These movements do not encompass the concept of rotational movement around an axis, which is why pivot is the appropriate choice for describing a turning motion around a long central axis.
