What maneuver is also referred to as the "hook" maneuver?

The term "hook" maneuver is commonly used to describe the anti-G strain maneuver. This technique is specifically designed to help pilots maintain consciousness and prevent G-induced loss of consciousness (GLOC) during high-G maneuvers. The anti-G strain maneuver involves tightening the abdominal and leg muscles in coordination with breathing techniques to increase blood flow back to the brain, counteracting the effects of increased gravitational forces.

By performing this maneuver, pilots can effectively prevent blood from pooling in the lower extremities, which can lead to a decrease in cerebral perfusion and subsequent loss of consciousness. The importance of training in this maneuver is crucial for pilots who operate under high-G conditions, ensuring they remain aware and in control during demanding flight scenarios.

The other options refer to different maneuvers or concepts that do not directly relate to this specific action of preventing the effects of G forces on the body.
