Excessive force during flight significantly impacts the cardiovascular system, primarily due to the increased physical demands placed on the heart and blood vessels. The cardiovascular system is responsible for transporting oxygen and nutrients throughout the body, as well as removing waste products. When excessive force is applied, such as in high-G maneuvers, the heart must work harder to maintain adequate blood flow and blood pressure.

High-G forces can lead to a range of physiological responses, including increased heart rate, changes in blood pressure, and the potential for G-induced Loss Of Consciousness (GLOC). The cardiovascular system must accommodate rapidly changing forces as well as ensure that blood is directed effectively to vital organs, especially the brain.

While other systems, like the respiratory and musculoskeletal systems, may experience effects from excessive force—such as altered breathing patterns or muscle strain—the cardiovascular system is primarily tasked with handling the immediate, acute changes in physical state that stem from the application of excessive force during flight. Therefore, it is the cardiovascular system that experiences the most pronounced effects under these conditions.
