Medical monitoring will take place throughout the study.

Measurement of muscle performance and capacity. Subjects will be monitored throughout and go through a medical check-up at the end of the study.

Beginning in September 2001, ESA, the French Space agency CNES and the Japanese Space agency NASDA start a unique experiment at the MEDES Space Clinic in Toulouse, France.
Fourteen test subjects aged between 29 and 41 will spend three months in bed to simulate the effects of long-duration Space Station missions. Throughout the study, the subjects will have to undergo many investigations such as tests during exercise, measurement of bone-density and magnetic resonance imaging… This is the first ever long-term bed rest study with so many scientific teams to be carried out in Europe.
