Description


Initial State:

VO2max, or maximal aerobic capacity, is a standard measure of aerobic fitness. Short duration space flight and bed rest analogs for space flight have demonstrated the occurrence of reduced aerobic capacity. These reductions hold the risk of impaired crew physical performance of required exploration mission tasks. The existence of the Internationals Space Station (ISS) created a platform to establish a time course for changes in in-flight and post-flight aerobic capacity.  This baseline response using current exercise countermeasures results can be used to compare against responses when implementing novel exercise countermeasures regimens.

Interim Stages: Research required to close this gap has been completed.  This gap will be closed following publication of the VO2max study.

Characterization of in-flight and post-flight VO
2max

 

 

Approach: In-flight and post-flight VO2max analysis was performed on 14 ISS crew members.

 

Target for Closure
Establishment of an in-fight time course for changes in ISS crew members as well as a characterization of immediate post-flight responses.
Mappings
