The term that refers to the motion of a body part moving away from the midline is abduction. Abduction is a fundamental movement pattern commonly discussed in the context of anatomy and kinesiology. It describes the action of lifting a limb away from the center of the body, such as raising an arm or leg sideways. This movement increases the angle between the limb and the midline, effectively moving the limb outward.

Understanding abduction is important for personal trainers, as it relates directly to various exercises and movements clients may perform. For example, exercises that involve lateral raises of the arms or leg lifts to the side are practical applications of abduction.

In contrast, adduction refers to the movement of a body part toward the midline. Dorsiflexion involves the movement of the foot upwards towards the shin, and elevation refers to lifting a body part superiorly, such as shrugging the shoulders. Each of these terms describes different movements within the body and is crucial for understanding biomechanics and exercise instruction.
