The effect of experience on the psychophysiological response and shooting performance under acute physical stress of soldiers. Physiology & Behavior. 2021;238:113489. DOI: 10.1016/j.physbeh.2021.1134890031-938410.1016/j.physbeh.2021.113489https://hdl.handle.net/20.500.14352/109270Present research studied the psychophysiological response and shooting performance taking into consideration the experience of the soldier after a physical stress protocol, which leaded to acute fatigue conditions. Sixty soldiers were divided into experienced and non-experienced groups to conduct a high-intensity interval training (HIIT) based on endurance type exercises (10 intervals of 40 m run at maximum intensity with 2 changes of direction and 45 s of recovery. Psychophysiological and shooting performance variables were measured before, during and after the HIIT protocol. Significant increases in heart rate, blood lactate, lower limbs strength, as well as a significant decrease in blood oxygen saturation and body temperature were found in both groups. Shooting performance was affected by experience and fatigue, being more accentuated in non-experienced. Present HIIT protocol elicited a similar psychophysiological response than in previously reported combat manoeuvres, thus proving to be an optimal stimuli approach/intervention for soldier's specific physical preparation.engjournal article1873-507Xhttps://doi.org/10.1016/j.physbeh.2021.113489https://www.sciencedirect.com/science/article/pii/S0031938421001797?via%3Dihubrestricted access159.944:355.11612.821Shooting performanceShooting accuracySoldiersExperienceHIITFatiguePsicología fisiológicaEstrés y relajaciónCiencia militar6106.10 Psicología Fisiológica6106.11 Reacción, Reflejos
