Which term refers to movements toward the midline of the body?

1. Abduction

2. Adduction

3. Flexion

4. Extension

The correct answer is: Adduction

The correct term for movements toward the midline of the body is adduction. This movement involves bringing a limb or a body part closer to the central line of the body. For example, when you bring your arms down to your sides after having them raised, you are performing an adduction movement. Adduction is an important concept in understanding how the body moves, especially during various exercises and activities. Recognizing these movements helps a fitness instructor guide clients in performing exercises correctly and ergonomically, ensuring that they are engaging the appropriate muscles while reducing the risk of injury. In contrast, other terms like abduction refer to movements away from the midline, while flexion and extension describe movements that involve bending and straightening limbs around joints. Understanding the distinction between these terms helps in effective communication and teaching within a fitness environment.
