Version Used During Ground-based Experiments

ROI_SLD
A harness was used to restrain a subject to the treadmill running surface. Two harnesses were used: a Russian-designed harness and the United States-designed harness. Both harnesses were tested because it is anticipated that both harnesses will be used on the International Space Station treadmill. Each harness was attached to the Subject Loading Device (SLD) by two methods: relatively non-compliant extender straps and compliant bungees.

ROI_BD1
Subjects used the Russian designed harness during the ROI BD-1 study. A bungee applied load to the subjects through a waist and shoulder harness. It was attached to the right and left side of the harness at waist level with adjustable extender straps that clipped to the metal terminations at each end of the bungee. The applied external load (EL) can be distributed between the waist and shoulders by adjusting the length of the shoulder straps. The EL can also be varied slightly by adjusting the length of the extender straps. Each subject was outfitted prior to data collection with the harness in a configuration that was deemed comfortable. The load distribution between the shoulders and waist was not standardized because there was no means to measure these load components independently.

The harness was worn during 0-G and 1-G trials with the positioning harness; during 1-G trials without the positioning harness, no harness was worn. During the positioning harness trials, the rearward-directed force was applied to the subjects using extender straps attached horizontally between the rear of the safety frame and the Russian harness worn by the subjects.

EORS_TVIS
The redesigned U.S. harness and the Cleveland Clinic Foundation Harness (CCF Harness) were the two harness designs evaluated in the TVIS Harness Comfort Study. The redesigned U.S. harness was engineered to more closely match the Russian harness based on crew comfort observations and is currently in use on the International Space Station (ISS). The CCF Harness design is a newly designed harness developed by the Cleveland Clinic Foundation which has been engineered using current state-of-the-art design concepts used by backpack manufacturers and designed with consideration to crew comfort observations.
