Muscle Tone in Space (Myotones)
Principal Investigator
Research Area:
Muscle physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
Investigators aim to access microgravity-induced biomechanical muscle parameters such as tone, tension, elasticity, relaxation, and creep on the relaxed muscles of the human body by means of the non-invasive MyotonPROTM device to access skeletal muscle status for better health monitoring of crewmembers during preflight training, inflight activities, and post-flight reconditioning.

This study has the following specific aims:

  1. To better understand the fundamental adaptation mechanisms related to the yet ill-defined structure-function-biomechanics interrelations of the human resting myofascial system exposed to long-term continuous microgravity.
  2. To gain a better and more comprehensive evaluation of the crewmembers performance control and fitness for variable mission duties (inflight monitoring).
  3. To perform routine monitoring on crewmembers before launch and after landing.
  4. To monitor in relation to preflight data the magnitude of changes throughout the full cycle of deconditioning on the International Space Station (ISS) and post-flight reconditioning.
  5. To monitor on which level due to regular exercise the astronauts will be able to maintain and even up the parameters measured by the MyotonPROTM on Earth versus the ISS.
  6. To monitor the microgravity changes of different tissue and muscle types.
