Which axis is perpendicular to the transverse plane?

The transverse plane, which divides the body into upper and lower parts, has an axis that is perpendicular to it known as the longitudinal axis. The longitudinal axis runs vertically through the body, facilitating movements such as twisting or rotation.

In this context, the correct answer highlights the fact that any movement occurring around the longitudinal axis must be perpendicular to the transverse plane. This alignment allows for effective evaluation of rotational movements, such as those that happen during activities like throwing, swinging, or rotating the torso.

Understanding the relationship between the transverse plane and the longitudinal axis is crucial for fitness trainers when designing programs that involve various types of body movements, ensuring that clients can perform exercises efficiently and safely. The other axes, while important in their respective contexts, do not align perpendicularly with the transverse plane in the same manner as the longitudinal axis does.
