Which of the following describes the functional center of gravity while sitting?

The functional center of gravity while sitting is effectively described by the position where the ankles and trunk flex forward, with the hands positioned forward. In this position, the body's weight is balanced toward the front, which is crucial for maintaining stability and functionality while seated. This posture allows for better engagement and control over tasks, especially those that require reaching or using the upper limbs, as it focuses the center of gravity within a more active range.

In contrast, other positions such as legs extended and back straight typically reflect a more passive posture that may not optimize functional mobility. Keeping the arms and hands at your side with feet flat may support a stable sitting position but does not facilitate active movements or reach. Additionally, having feet positioned above the knees while the back is arched can lead to an unstable posture, emphasizing a forward lean that may compromise balance and limit functional use of the body for activities.
