First of all, it is important to understand that parachuting is also a kind of sport, and the core physical qualities of this sport are cardiopulmonary function, balance and spatial perception, as well as anti-dizziness and anti-pressure capabilities.
In the high-altitude, low-pressure environment and during rapid descent, the heart and lungs will be subjected to great stress.
At high altitudes without references, there is a need for precise judgment of body posture, relying heavily on vestibular function and muscle memory to maintain stability and avoid spiral descent.
Additionally, during high-speed rotation and turbulence, dizziness can occur, so parachutists need to have a very strong anti-dizziness ability.
On this basis, the moment the parachute opens, there is an overload of several Gs. Li Younan now feels that the top-notch overload experienced by fighter jet pilots during takeoff might be no different from this.
