To examine the effectiveness of artificial gravity and ergometric exercise as countermeasure to these changes, 12 healthy young men were exposed to stimulated microgravity for 20 days by Head-Down Bed Rest (HDBR). Six subjects randomly selected were subjected to 1.4 G of artificial gravity with 60 W of ergometric workload everyday for 30 minutes (CM group). The rest of the subjects served as the control (control group). In head-up tilt test and Anti-G test, body fluid shifts to downward in upper body by HDBR. This body fluid shift was prevented by countermeasure. Also, myatrophy measured by MRI (Magnetic Resonance Imaging) in the thigh was smaller in CM group than in control group. Artificial gravity with exercise appeared to be effective in preventing changes in body fluid shift and myatrophy due to microgravity exposure., 資料番号: AA0063706076}, pages = {278--280}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Head-down bed restにより生ずる体液移動と筋萎縮への対抗措置の効果}, year = {2008} }
