What does the acronym AGSM stand for in aerospace physiology?

The acronym AGSM stands for Antigravity Straining Maneuver, which is a technique used by pilots and aircrew to help counteract the effects of high gravitational forces (G-forces) experienced during flight maneuvers. This maneuver involves specific body positioning and muscle contractions to maintain blood flow to the brain and prevent G-induced Loss Of Consciousness (GLOC). By effectively engaging core muscles and using proper breathing techniques, the Antigravity Straining Maneuver helps to maintain consciousness and physical performance under conditions of high acceleration. Understanding this technique is critical for pilots, as it enhances their ability to manage physiological stress during combat or aerobatic operations.
