Description
The AGBRESA (Artificial Gravity Bed Rest with ESA) project was a collaboration between NASA's Human Research Program (HRP), the European Space Agency (ESA), and the German Space Agency (DLR).

Investigators studied the effects of artificial gravity on the physiological changes induced by six-degree head down tilt (HDT) bed rest. HDT bed rest was used to simulate microgravity, while artificial gravity was created through use of a human-rated short arm centrifuge.

12 subjects participated in 14 different investigations. Three were funded by HRP, seven by ESA, and 4 by DLR.

Subjects completed two weeks of training and baseline data collection, followed by sixty days of HDT bed rest. While undergoing bed rest, 4 subjects received 30 minutes of continuous centrifugation; 4 subjects underwent a pattern of 5 minutes of centrifugation, 3 minutes of rest, for a total of 30 minutes of centrifugation; and the final group of 4 subjects did not receive any centrifugation, serving as a control group. Subjects completed their participation with post bedrest data collection.

This was the first of two parts of the project carried out at the :envihab facility operated by the DLR’s Institute for Aerospace Medicine in Cologne, Germany.
