What does the sagittal plane do?

The sagittal plane is a vertical plane that divides the body into right and left sections. This division occurs along the body's midline, creating two halves that are mirror images of each other at the center. Movements that happen within this plane typically involve forward or backward motions, such as flexion and extension, which occur at joints like the elbow or knee.

Understanding the functions of different anatomical planes is essential for fitness professionals, as it informs how exercises are categorized and helps in creating effective training regimens that target specific muscle groups in relation to their movements. In contrast, other planes such as the frontal (which divides the body into front and back) or the transverse (which divides the body into upper and lower regions) serve different purposes related to body movement and orientation. The sagittal plane's specific role in delineating right from left makes it foundational in biomechanics and kinesiology.
