Description
OBJECTIVES:
This International Space Station (ISS) in-flight technology demonstration is being conducted to evaluate the MED-2 as a potential resistance and aerobic exercise device for use during time aboard the Multi-Purpose Crew Vehicle (MPCV). For demonstration on the ISS, the MED-2 device will be securely attached to the ARED plate. Astronauts will be asked to participate in a minimum of two and up to four in-flight sessions consisting of deadlift resistance exercise and aerobic rowing exercise. Astronauts will be asked to tape markers to specific anatomical land marks, set-up video cameras, and wear a heart rate monitor to allow for biomechanic and physiological data collection during each session. A member of the investigative team and an Astronaut, Strength, Conditioning, and Rehabilitation (ASCR) group will be on-console to provide real-time guidance. The astronaut will be asked to complete a questionnaire regarding MED-2 usability after each session.

The first session will serve as a familiarization of the MED-2, and load setting verification for subsequent sessions. The subsequent session(s) will be biomechanic and heart rate data collection sessions. If proper deadlift and rowing form at high, medium, and low loads with proper camera placement for biomechanical evaluation are demonstrated and quality heart rate data is collected during the first two sessions then no additional sessions will be requested. Subsequent sessions will only include the exercise (rowing or deadlift) that did not meet success requirements.

Primary objective:
Evaluate the operation of a single-loading output exercise device to accommodate exercise body movement effectively in weightless environment.

Secondary objectives:

  1. Evaluate the ability to achieve effective aerobic exercise with rowing in weightless environment.
  2. Evaluate the kinematics of exercising with single cable device in microgravity.
  3. Identify the operational volume needed to perform planned MPCV exercises.
  4. Identify the foot placement area during exercise to inform MPCV foot plate requirements.
