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.
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:
- 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.
- To gain a better and more comprehensive evaluation of the crewmembers performance control and fitness for variable mission duties (inflight monitoring).
- To perform routine monitoring on crewmembers before launch and after landing.
- 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.
- 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.
- To monitor the microgravity changes of different tissue and muscle types.
