Horizontal abduction and adduction occur in which plane?

Horizontal abduction and adduction occur in the transverse plane, which is also known as the horizontal plane. This plane divides the body into upper (superior) and lower (inferior) parts and allows for rotational movements. Horizontal abduction refers to the movement of a limb away from the midline in a horizontal manner, while horizontal adduction refers to the movement of a limb towards the midline in the same plane. These movements are primarily seen in the shoulders and hips, emphasizing the role of the transverse plane in facilitating actions that require rotation. Understanding this concept is crucial for trainers and fitness professionals when designing exercises that target specific movements and muscle groups efficiently.
