End of the BRAHMS clinical study

 

That’s a wrap on an extraordinary scientific adventure!

After a 21-day study, the 10 volunteers of the BRAHMS study (Bed Rest And HypoMetabolism Study) left the space clinic facilities at the end of June. BRAHMS was:

  • A CNES study conducted by MEDES

  • 10 healthy volunteers aged 20 to 40

  • 12 French scientific teams involved

  • 20 days of clinical research, including 10 days of weightlessness simulation through bed rest combined with severe fasting (250 kcal)

 

The objective? To evaluate the physiological adaptation mechanisms of the 10 volunteers to this bed rest (at a -6° head-down tilt) combined with hypometabolism. This was done to prepare for future spaceflights and anticipate potential unforeseen situations in space (life-support system failure, resupply failure, or extended mission duration).

As a model of extreme sedentary behavior, these studies are also particularly useful for “health on Earth.”

BRAHMS was a physically demanding study, intense for the teams, but a resounding success!

We would like to warmly thank everyone involved in making this study a success.

A big thank you to:

  • CNES for their continued trust in carrying out these studies.

  • The volunteers, who formed a motivated, dedicated, and passionate group! Thank you for your resilience!

  • The 12 scientific teams for the excellent collaboration, smooth testing procedures, and promising incoming results.

  • Toulouse University Hospital (CHU de Toulouse) for their support throughout this study, for hosting various medical exams, and for the logistical and catering support.

  • The healthcare staff who accompanied us and did a fantastic job.

  • Finally, congratulations to the entire MEDES space clinic team for your commitment and professionalism over the long months of preparation and its flawless execution.

Another great challenge successfully met in service of human space exploration!
