||Group dynamics and catecholamines during long-duration confinement in an isolated environment

||The objective of this study was to investigate possible relationships between catecholamine excretion and long-duration confinement in an isolated environment. Stays of long duration in a confinement chamber were made by three groups of four subjects each: an all-Russian team during weeks 1-34; a mixed-nationality team during weeks 3-18; a mixed-nationality team during weeks 22-38. Other groups joined the residents for one-week intervals at weeks 13, 19 and 33. Epinephrine excretion generally remained in the normal range. However, occasional elevations occurred due to psychological stress, which apparently correlate with changes in group dynamics. Norepinephrine excretion was above the normal range and was correlated with social events. These results suggest that to ensure optimum crew performance, entire crews along with their visiting crews should be selected collectively, rather than individually.
