When deployed, MARES was attached to the seat tracks of an International Standard Payload Rack (ISPR) located in the Columbus Laboratory.
MARES is capable of providing quantifiable stimuli to a wide range of space flight participants and accurately measuring these crew-members' muscle performance.
The main box also contains power, control, supervision, and servo drive electronics, cooling fans, and a connector panel used to connect the HRF workstation and other external devices to MARES, such as PEMS II.
The restraint system also includes a pantograph, which is capable of translating and rotating the chair into a wide range of positions relative to the main box.
BMUs can be combined into distinct MARES profiles to create complex motions and to simulate common exercise routines used on Earth.
