Bedrest was performed with 2,300 kcal of diet. Water intake was recommended more than the urine volume in a previous day. A new protocol for artificial gravity with ergometric exercise was adopted, with 1.6 G of artificial gravity and 60 W of exercise every day and 0.3 G artificial gravity with 80 percent of maximum oxygen intake. Gravity tolerance was examined by using centrifuge, and anti-G score was determined before and after the bedrest. Not all result has been analyzed, however, effectiveness of artificial gravity with ergometric exercise was evidenced in orthostatic tolerance, physical fitness, cardiac function, myatrophy, and bone metabolism. We concluded this protocol was effective in cardiovascular deconditioning myatrophy, and bone metabolism., 資料番号: AA0063349076}, pages = {269--272}, 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 = {20日間-6度ヘッドダウンベッドレストに伴う宇宙飛行デコンディショニングに対する人工重力および運動負荷の対抗措置としての有効性}, year = {2007} }
