Key result
Underwater evacuation training significantly increased subjective stress perception and sympathetic nervous system modulation similarly in both crew and medical members, without affecting memory or cortical arousal.
Why the study?
The study aimed to analyze the effect of experience and professional role on the psychophysiological stress response during underwater evacuation training.
Observational (n=36)
Underwater evacuation training induces significant anticipatory anxiety and sympathetic nervous system activation in military personnel, regardless of their specific professional role.

Underwater evacuation training may heighten sympathetic stress without impairing cognition or strength; leaves open tailoring by role or experience.
Background: This research aimed to analyze the effect of experience and professional role on psychophysiological stress response in underwater evacuation training. Methods: We analyzed 36 participants (39.06±9.01 years), divided into two different groups; 17 crew members (38.6±7.2 years) and 19 medical members (39.5±10.5 years). modifications in the rating of perceived exertion, subjective stress perception, heart rate, blood oxygen saturation, cortical arousal, heart rate variability, spirometry, isometric hand strength, and short-term memory before and after underwater evacuation training were analyzed. Results: The maneuver produced a significant increase in SSP, RPE, IHS, FVC, and SatO2 at different moments of the intervention, being higher in crew members. Conclusions: We found that the underwater evacuation training produced an anticipatory anxiety response, and an increase in autonomous sympathetic nervous system modulation not affecting strength capacities, cortical arousal, and memory independently of the aircraft role (medical or crew).

Vicente-Rodríguez et al. (2024) conducted an observational in Psychophysiological stress (n=36). Underwater evacuation training vs. Pre-training baseline and between professional roles (crew vs medical) was evaluated on Psychophysiological stress response (including subjective stress perception, heart rate variability, and rating of perceived exertion). Underwater evacuation training significantly increased subjective stress perception and sympathetic nervous system modulation similarly in both crew and medical members, without affecting memory or cortical arousal.
