The study, titled "CFT 70 (
Countermeasure and Functional Testing in Head-Down Tilt Bed Rest Study)," aimed to learn more about how human bone and muscle might deteriorate in space. According to Drew Iwanicki, who took part in the study and who is pictured above, he experienced some serious headaches because of increased blood pressure to his head. His spine went through some serious pain, and staying horizontal was difficult. However, as soon as the bed was tilted to the vertical position, after 70 days of course, his legs felt heavier and his heart started to beat at 150 BPMs.
