Summary

DescriptionMuscle Figure 6-4.jpg	English: Figure 6-4. The first U.S. “treadmill” utilized during spaceflight was a passive device used only on the Skylab 4 mission of 84 d duration. The high loading (175 lbs) via bungee cords provided more of a resistive rather than an aerobic modality. It consisted of a Teflon-coated aluminum plate attached to the Skylab isogrid floor. The exercising crewmember wore a waist and shoulder harness that attached to the iso-grid floor surrounding the treadmill plate by means of 4 bungee cords. Socks had to be worn to provide a low-friction interface between the plantar surface of the feet and the Teflon-coated treadmill plate. From reference.
