This study investigated time patterns and the relationships between perceived stress, recovery, control, attention lapses, and defense mechanisms (DM) during a 12-month wintering in Concordia polar station with an international crew of 14 volunteers. This ICE (Isolated, Confined, Extreme) environment induced some stress, mainly in the social dimension and showed relationships (a) between DM and both stress and recovery and (b) between recovery and perceived control, highlighting the roles of DM and control in psychological adaptation. These results offer additional insights into the affective, social, and cognitive processes involved in adaptation. The findings suggest that preventive psychological countermeasures should be developed for crew members to counteract detrimental psychological outcomes and to improve adaptation to long-duration ICE situations such as planned human interplanetary space missions.

These psychosocial issues have important implications for pre-mission selection and training, monitoring and support of crews during the mission, and post-mission readaptation. Operational recommendations are suggested to improve adaptation, success, and well-being for long-duration ICE missions, e.g., to Mars and beyond. Nicolas M, Bishop SL, Weiss K, Gaudino M.

Objectives: The aim of this study was to: (a) examine the time courses of runners' recovery-stress states within the month following a demanding Mountain Ultra-Marathon (MUM) race; and (b) explore the role of primary and secondary appraisals in these trajectories. Design: A seven-wave one-month longitudinal design was used with one measurement point within two days before the race to measure appraisals and six time points within the month following the race to assess recovery-stress states experienced by athletes. Method: A multilevel growth curve analysis approach was used among a sample of 29 MUM runners. Results: Recovery-stress states were characterized by distinct trajectories during the month following MUM race. Results of multilevel growth curve analyses showed significant linear increases of general and total recovery, significant linear decreases of general, sport-specific and total stress and a positive quadratic effect of squared time (U shape over time) on specific recovery. Primary appraisal significantly positively predicted levels of sport-specific recovery, total, general and sport-specific stress and significantly negatively predicted total and general recovery. Secondary appraisal significantly negatively predicted total and general stress. Conclusions: This study provided insights into the role played by appraisals on the recovery-stress states experienced by MUM runners the month following a demanding MUM race. Operational strategies were suggested in order to optimize the recovery-stress balance and in turn psychological adaptation processes in response to an ultra-endurance race.
