For five weeks, participants lie at a six-degree angle and leave the bed only when performing exercise training. In this position, subjects show physiologic changes similar
to those expressed by astronauts in microgravity for long periods.

Levine’s study measures the effectiveness of strength training combined with rowing exercise and supplementation as an integrated program to offset the effects of microgravity on the body. Jeffrey L. Hastings, M.D., and Peter Snell, Ph.D., direct
strength-training exercises performed by a bed-rest study participant. (Photo courtesy of UT Southwestern.)
