Risk of Single Appraisal in Complex Environment: Physical and Perceived Stress in Military Training on Amazon Jungle

The aim of this study was to investigate the correlation between perceived and physical stress in a wearing military training in an environment of Amazon forest.For this, 48 volunteers from the Brazilian Army underwent inventory PSS-14 and blood samples were collected immediately before and at the end of an adaptation to life in the jungle training. Differences and significant positive correlations between all the biochemical variables and between pre and post samples were detected. The mean LDH post and CK post were outside of normal parameters, which points to the manifestation of physical stress during the training. No correlation between perceived stress pre/post and any biochemical variable related to physical stress was found.The results of this study suggest that the perception of control and emotional stability alone cannot be taken into consideration in the management of resources and decision-making in situations of obvious fatigue.
