ABSTRACT
The current military training requires the development and optimization of different strategies to improve performance in extreme conditions as well as the possible risk of suffering attacks with chemical and/ or radioactive substances. It turns out mandatory to research the psychophysiological response of soldiers and sanitary personnel when wearing the nuclear, biological and chemical (NBC) equipment. A longitudinal prospective experimental quantitative study has been developed, using a pre-treatment and post-treatment design. A total of 20 soldiers (33.3⯱â¯5.4 years), belonging to the Spanish Armed Forces have been analyzed, divided into two groups, when carrying out different training activities designed to that effect. The following variables were analyzed right before and after accomplishing the different tasks: heart rate, heart variability, thermoregulation, blood glucose, explosive strength, perceived effort and motion performance in a munitioning task. The results showed a significant increase (pâ¯<â¯05) in heart rate, blood glucose, perceived effort and the time required when developing the triage tasks and when putting a tourniquet on other person in the group wearing NBC equipment compared to the other group, as well as a longer time required in a munitioning task. These results highlight the importance of training and preparing the sanitary and military personnel in the use of NBC equipment.
