Combined Operational Load Bearing External Resistance Treadmill (COLBERT) - 05.13.15
The Combined Operational Load Bearing External Resistance Treadmill (COLBERT) will be used to maintain bone, muscle, and cardiovascular conditioning on the International Space Station crewmembers. The COLBERT is instrumented to collect inflight research-grade data for experiments that are representative of critical mission tasks on future long-duration exploration missions.

Previous ISS Missions
The COLBERT will be the second treadmill on the space station. The first was Treadmill with Vibration Isolation System (TVIS) which was overhauled during Expedition 20.
- The COLBERT (Combined Operational Load Bearing External Resistance Treadmill) will be the second treadmill on the International Space Station, adding to a complement of six different exercise devices already on board the ISS.
- This new treadmill is a critical countermeasure device that will be used to keep the ISS crewmembers healthy while on-orbit and helps prepare them for return to Earth.
- The COLBERT features data collection devices that will allow scientists and doctors to evaluate how effective the treadmill exercise is in reducing the amount of bone and muscle density loss due to microgravity exposure.
- The COLBERT is designed so that ground experts can track crew health on orbit to create individual exercise prescriptions and uplink them to the crew. The information sent down to the ground experts will be used to determine how well the crewmembers are being conditioned or lack thereof and to adjust exercise prescriptions accordingly.
- (Powered) Active Mode: Tread belt driven by an electric motor (normal treadmill)
- (Powered) Passive Mode: Runner moves belt by pushing with his/her feet, motor resists tread motion, motor peak current provides adjustable resistance
- Unpowered Mode: Motor is completely unpowered, runner pushes the belt with his /her feet, and the resistance is solely from the rolling resistance of the system
- The COLBERT will allow a single crewmember to configure the device for any exercise configuration in less than 10 minutes from the untended or stowed configuration, or from any other exercise configuration and toggle power on and off with a single control.
- The treadmill belt will begin movement and the exercise session initiated via crew action. The crewmember will be able to log into the system by selecting their name from a list and entering a unique private Personal Identification Number (PIN). A cool down protocol is also implemented that will take no more than a discrete single action for operation, last for five minutes and maintain speed of no less than 3.2 km/hr (2 mph) during the cool-down period.
- The Treadmill will have a safety stop to remove power from the motor.
