high-G training

High-G training is done by aviators and astronauts who are subject to high levels of acceleration ('G').

During the eight days in a vacuum hypobaric chamber, directly after the high-g training, Gridunov faced the artificial heat and the lack of oxygen while testing the temperature control system.

High-G training for pilots of high performance aircraft or spacecraft often includes ground training for G-LOC in special centrifuges, with some profiles exposing pilots to 9 gs for a sustained period.
