The aim of this paper is to present the structure of fitness training and its impact on overcoming G-forces in military pilots. The paper is based on a theoretical framework and does not include any sample analysis. Fitness treatments have a significant impact on reducing the effect of gravitational force (G-force) in military pilots. G-force is the force exerted on the pilot's body during a rapid change in direction or speed of the aircraft, which can lead to physiological problems such as loss of consciousness (G-LOC) due to reduced blood flow to the brain. This is why it is extremely important that pilots are physically prepared to withstand these extreme conditions. Regular fitness training, especially those focused on strengthening the cardiovascular system and musculature, is key to increasing G-force resistance. Aerobic exercises such as running, swimming and cycling improve the capacity of the heart and lungs, thereby ensuring better blood flow and oxygen supply. Anaerobic exercise, including weight lifting and resistance exercise, strengthens muscles, especially those in the trunk and lower body, which help maintain stability and blood circulation during exposure to high G-forces. One of the key elements of the training is the specific training to withstand the G-force, which includes exercises such as isometric contractions of the leg and abdominal muscles, which help maintain blood pressure and reduce the risk of G-LOC. Also, pilots are trained in proper breathing and the use of anti-G suits that further help maintain blood circulation. Studies have shown that pilots who regularly participate in structured fitness programs have better physical condition, a lower risk of G-LOC and a greater ability to react quickly during flight. In addition to physical benefits, fitness training also contributes to a pilot's mental health, reducing stress and increasing overall resilience to the challenges of flying at high G-forces. Fitness treatments are essential for military pilots because they significantly improve their physical fitness, G-force resistance, and overall ability to safely and effectively perform aviation missions.
