Definition accommodating resistance

It provides the interfaces between the exercise rope and the Arm Base Assembly via the Cable Arm Ropes to provide load for the exercises. Exercise Bench Assembly is an accessory that mounts to the platform and provides a surface for performing shoulder presses, bench presses, and other seated or lying exercises.

Situps and other core exercises can be performed using the bench as well. Heel Block Assembly is an accessory that mounts to the platform and allows the capability for performing heel-raise exercises. The ARED operates in the following modes: Resistance is provided by the movement of pistons within the vacuum of the cylinders.

The vacuum canisters provide the primary force while the flywheels provide the simulated inertial component of the exercise as would be experienced on the ground. Main Arm Assembly includes the wishbone arm and the lift bar components. Arm Base Assembly includes the load adjustment mechanism, interfaces for the Cylinder/Flywheel Assembly, Main Arm Assembly, Cable Pulley Assembly, and the Frame/Platform Assembly.

These assemblies contain two load cells and, one rotational sensor.

ARED users see results similar to those from free-weight training, suggesting that it could be an effective countermeasure against loss of conditioning during spaceflight.The Advanced Resistive Exercise Device (ARED) uses adjustable resistance piston-driven vacuum cylinders along with a flywheel to system to provide loading for crew members to experience load and maintain muscle strength and mass during long periods in space.Exercising in space poses unique challenges, but without exercise, astronauts can lose up to 15 percent of their muscle mass, some of it permanently.In addition, load sensors in the main lift arm and the arm base assembly measure unidirectional forces.The arm base assembly also has a rotational sensors that record the range of motion of the arm.
