Scientific Name: Homo sapiens Species: Human


Maximal Aerobic Capacity, VO2max, is one of eleven International Bedrest Standard Measures conducted on healthy subjects at the :envihab facility in Cologne, Germany. VO2max is directly related to the physical working capacity of an individual. An individual’s VO2max is affected by uptake of oxygen in the lungs, extraction of oxygen from the arterial circulation by working muscles and by cardiac output. Aerobic deconditioning causes a lowering of VO2max, which results in a diminished capacity to perform strenuous physical tasks. The purpose of the standard measures project is to populate a repository with data that enables high-level monitoring of countermeasure effectiveness and meaningful interpretation of health and performance outcomes. These standard measures will support future, hypothesis-driven research that enables planetary missions by providing an optimized minimal set of measures captured from subjects. These measures will be available to other studies under data sharing agreements as well as undergo analysis to understand risk posture.
