Gravity
Increased gravity can be studied in the human centrifuge or
can be simulated by lower body negative pressure.

Micro Gravity
Microgravity can be simulated in several ways in the
laboratory. First by using water
immersion, which can be accomplished in the annular pool, thermal water bath,
immersion tube, total body plythosomograph or by head-down tilt or lower body
positive pressure.
