    Facility Description

    Facility Overview

    The Combined Operational Load Bearing External Resistance Treadmill (COLBERT) is the second treadmill on the International Space Station (ISS) and is part of a complement of six different exercise devices onboard the ISS. Together, the ISS exercise equipment is used to prevent bone, muscle, and cardiovascular conditioning loss, as well as sensorimotor deconditioning in a microgravity environment.
     
    In mid-2009, the ISS expanded from three person to six person operations. COLBERT accommodates the exercise needs of a six-member crew and is a critical countermeasure device for maintaining crew health on-orbit and for preparing the crew for their return to the 1g environment on Earth. In microgravity, astronauts do not use their muscles as much as on Earth. Without exercise, these muscles begin to atrophy (waste away), potentially leading to bone density loss with symptoms similar to osteoporosis.
     
    COLBERT collects data that allow scientists and physicians to monitor the efficacy of the treadmill in providing intended workout intensities to the crew. helps prepare them for return to Earth.
     
    Ground experts create individual exercise prescriptions and uplink them to the crew. Data from the exercise sessions is downlinked and used to evaluate conditioning effects. Exercise prescriptions are adjusted and customized, accordingly.
     
    COLBERT is designed to allow walking and running in a microgravity environment for maintaining crew cardiovascular fitness, muscular strength, and to exercise neurophysiological pathways and reflexes that are required to walk once returned to Earth. In addition, the treadmill minimizes the transfer of dynamic forces caused by the operation of the treadmill so that excessive loads are not transferred to the Space Station structure.
     
    The treadmill and supporting subsystems (power, cooling, etc.) are located in an International Standard Payloads Rack (ISPR), and the vibration isolation system (VIS) is a modified Passive Rack Isolation System (PaRIS). The harness that the subjects wear can be adjusted to redistribute body loading more comfortably through the hips and shoulders, and tension on the bungees that interface the crew to the treadmill can also be adjusted, depending on how much load is prescribed.
     
    The treadmill operates in the following modes: 1) Powered Active Mode: tread belt driven by an electric motor (normal treadmill) and  2) Powered Passive Mode: runner moves belt by pushing with his/her feet, motor resists tread motion, motor peak current provides adjustable resistance.
     
    The Treadmill operates in a series of time-controlled stages, in which each stage consists of a prescribed load and speed. The Treadmill also operates from a pre-programmed protocol that is individualized and uplinked from the ground for powered active and passive modes. It also allows crew members to input and adjust exercise protocols, in powered active and passive modes, before and during exercise. A crew member can extend an exercise session without re-starting the protocol, and without interrupting data acquisition. In the active mode, the Treadmill provides speeds from 2.4 to 20 kilometers per hour (km/h) (1.5 to 12.4 mile per hour (mph)), with tread belt speed adjustment in 0.16 km/h (0.1 mph) increments.

    Operations

    Facility Operations

    • COLBERT allows a single crew member to configure the device for exercise in less than 10 minutes.
    • The tread belt begins movement and the exercise session is initiated via crew action. The crew member logs into the system by selecting his or her name from a list. A cool down protocol is available.
    • The Treadmill has a safety stop to remove power from the motor, if necessary.
