Last summer, the German astronaut Alexander Gerst embarked on a research trip on the ISS. This was the first time a mobile spiroergometry device had been launched into space. During six months, Alexander Gerst used the METAMAX® 3B to determine the impact of the space journey on the human organism. Not only the launch into space is exhausting. Being in orbit, the fitness changes and the journey back to earth is often more exhausting than the beginning.

The project which is accompanied by the Institute of Aerospace of the TU Dresden is not just about assessing astronaut’s fitness level. The results of the experiment will help to optimally prepare future space tourists on their flight into space.
