Description

Initial State: Loss of muscle performance metrics such as strength, power and endurance following space flight is well documented. What is currently unknown is the time course for changes in muscle performance during long duration space flight and the extent to which in-flight and post-flight muscle loss can be prevented with current International Space Station exercise countermeasures capabilities. Understanding the time course is critical to extending mission durations.


Interim Stages:

Characterization of post-flight strength loss
Characterization of post-flight strength recovery
Establishment of a timeline of in-flight strength loss


Approach:
Hypothesis driven and/or descriptive research that collects human data from long duration space flight and space flight analogs will be performed in order to provide the needed information.


Target for Closure
An established time course for (whole body) muscle performance changes during and following long duration space flight. Priority is given to establishment of a detailed time course (every 14-30 days) of muscles of the lower body as those are the most affected by spaceflight and very likely the most important for performance of strenuous mission tasks.
