This invention discloses a multifunctional integrated space physiological countermeasures and movement assistance suit and its control method. The spacesuit includes: a negative pressure fluid regulation system that applies controllable negative pressure to regulate fluid distribution; a biomimetic muscle system that applies controllable torque to simulate muscle exertion; an axial loading system that applies longitudinal compressive stress to simulate bone compression; and a control system that coordinates the operation of each system. In a preferred embodiment, the negative pressure system has multiple sealed zones with the negative pressure value increasing from the head side to the foot side and synchronizing with the cardiac cycle. The biomimetic muscle system can switch between assisted, resistive, and free modes. The axial loading system includes independent subsystems for the cervical spine and trunk-lower limbs. This invention is the first to integrate zoned stepped negative pressure, synchronized cardiac cycle regulation, biomimetic muscle coordination, and graded axial loading into a single wearable system, enabling all-weather simulation of Earth's gravity effects and addressing issues such as head-to-head fluid shift, muscle atrophy, bone loss, and disuse changes in the spine under microgravity.
