Question

During a physical fitness evaluation, an athlete moves their leg sideways away from the central midline of the body. This specific joint movement is classified as:

• A. \( \text{Abduction} \)
• B. \( \text{Adduction} \)
• C. \( \text{Flexion} \)
• D. \( \text{Extension} \)

Hint:

Use this simple linguistic trick to keep them straight: ABduction means a limb is taking off about or away, while ADDuction means you are bringing the limb back to add it to your torso midline.

Answer 1

The Correct Option is A

Concept: Kinesiology maps human movement across standard anatomical planes using relative vector alignments:

• Flexion/Extension: Movements occurring in the sagittal plane that decrease or increase the angle between joint components.
• Abduction/Adduction: Lateral movements occurring in the frontal plane relative to the body's vertical midline axis.

Step 1: Define the direction of movement relative to the anatomical midline.
When a limb moves laterally away from the central longitudinal midline of the body (such as raising the arms or legs straight out to the sides), the movement is defined as Abduction.

Step 2: Contrast with the returning movement trajectory.
The opposite movement, which draws a limb back toward the central axis of the body, is called Adduction (think of "adding" the limb back to the body).
