What happens to fascial sheaths when a person stands still?

When a person stands still, the fascial sheaths undergo a process where they can gel up, which refers to the phenomenon of increased viscosity or stiffness in the fascial tissues due to lack of movement. This gel-like state occurs because fascia is a living tissue that responds to the demands placed upon it. When the body remains still for an extended period, the fluid within the fascia can become less mobile, resulting in a temporary state that resembles gel.

Upon movement, this viscous fascia can return to a more fluid state, allowing for better flexibility and mobility. This property of fascia is essential for facilitating movement and reducing restrictions in the body, highlighting the importance of regular movement to maintain optimal fascial health.

In contrast, the other options do not accurately describe the behavior of fascial sheaths under stillness. They may imply a static or negative change, while the correct choice reflects the dynamic nature of fascia as it responds to inactivity.
