Salivary Markers of Metabolic Changes during Space Missions (Bone_Muscle_Check)
Principal Investigator
Research Area:
Skeletal physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

The experiment investigates on the use of saliva to monitor metabolic changes associated with in-flight reductions in bone and muscle mass. Space Research: reliability of saliva as a simple tool to monitor metabolic changes during space mission and possibly to tune-up countermeasures against microgravity-induced reduction in bone and muscle mass. Earth-based Research: reliability of saliva as a simple tool in settings where the blood withdrawal is difficult or impossible.
