Attention needs to be paid to diet; for the data to have any validity, they must be collected under conditions where subjects are in or at least near to energy balance. On missions with a heavy exercise component, there is apparently a problem in maintaining energy balance.
The available in-flight human data, principally from Skylab and SLS-1 and SLS-2, shows little evidence for any gross changes in growth hormone (GH), even though rodent studies suggest that spaceflight may have a unique effect on the HPA axes.
