What is the function of the frontal axis in human movement?

The function of the frontal axis in human movement is accurately described as running through a joint from side to side. This axis allows for movements that take place in the sagittal plane, which is where flexion and extension occur. For example, when performing lateral raises or side bends, the body is moving around this axis. Understanding this concept is crucial for analyzing how different exercises or movements are performed and how they impact the body’s biomechanics.

The other options refer to different axes or concepts related to motion. The option about running from front to back describes the sagittal axis, while the description about denoting the center of balance relates more to stability and posture rather than a specific axis of movement. Similarly, the mention of points of force application is more aligned with principles of biomechanics and how forces interact during movement, rather than specifically describing the function of the frontal axis in movement.
