Which stretch requires assistance from an external source like gravity or a partner?

Passive stretching involves an external source, such as gravity, a partner, or a prop like a strap or wall, to assist in achieving a deeper stretch. In this type of stretching, the individual relaxes their muscles while an external force causes the stretch, allowing for a greater range of motion than might be possible through active efforts alone.

This technique is beneficial for improving flexibility since it enables the muscles to relax and elongate with the help of another entity, as opposed to relying solely on the individual’s strength to achieve the stretch. Passive stretching is often incorporated into cool-down routines or rehabilitation protocols to enhance flexibility while minimizing the risk of injury.

In contrast, isometric stretches involve muscle contraction without changing the muscle length, dynamic stretches include movement-based activities to warm up the body, and static stretches involve holding a position for a period without additional assistance. Each of these methods serves distinct purposes but does not rely on an external force in the same manner as passive stretching does.
