Which joint action is characterized by moving a limb closer to the midline of the body?

  1. Flexion

  2. Extension

  3. Adduction

  4. Abduction

The correct answer is: Adduction

The action of moving a limb closer to the midline of the body is known as adduction. This term specifically describes the movement toward the center of the body, contrasting with abduction, which refers to moving a limb away from the midline. Adduction is commonly observed in various exercises and movements, such as bringing the arms down to the sides of the body or bringing the legs together. Understanding joint actions like adduction is essential for personal trainers, as it helps in developing effective workout programs that target specific muscle groups and movement patterns.
