We aimed to analyse the effect of combat stress in the psychophysiological responses of elite and non-elite soldiers. We analysed heart rate, cortical arousal, skin temperature, blood lactate concentration and lower body muscular strength before and after a tactical combat simulation in 40 warfighters divided in two groups: elite (n: 20; 28.5 ± 6.38 years) and non-elite (n:20; 31.94 ± 6.24 years) group. Elite presented a significantly higher lactate concentration after combat than non elite soldiers (3.8 ± 1.5 vs 6.6 ± 1.3 mmol/L). Non-elite soldiers had a higher heart rate pre and post the simulation than elite (82.9 ± 12.3 vs 64.4 ± 11. pre non elite and elite respectively; 93.0 ± 12.8 vs 88 ± 13.8 bpm post non elite and elite respectively). Elite soldiers presented higher lower muscular strength than elite in all test and before and after the combat simulation. Cortical arousal was not modified significantly in both groups. We conclude elite soldiers presented in combat a higher anaerobic metabolism activation and muscular strength than non-elite soldiers, but cardiovascular, cortical, and muscular strength manifestation presented the same response in both elite and non-elite soldiers.
我们旨在分析战斗压力对精英士兵和非精英士兵心理生理反应的影响。我们对40名战士进行了战术战斗模拟，将他们分为两组：精英组（n = 20；28.5 ± 6.38岁）和非精英组（n = 20；31.94 ± 6.24岁），并分析了模拟前后他们的心率、皮层唤醒、皮肤温度、血乳酸浓度和下肢肌肉力量。战斗后，精英组的乳酸浓度显著高于非精英组士兵（分别为3.8 ± 1.5 vs 6.6 ± 1.3 mmol/L）。模拟前后，非精英组士兵的心率均高于精英组（非精英组和精英组模拟前分别为82.9 ± 12.3 vs 64.4 ± 11；非精英组和精英组模拟后分别为93.0 ± 12.8 vs 88 ± 13.8 bpm）。在所有测试中以及战斗模拟前后，精英组士兵的下肢肌肉力量均高于非精英组。两组的皮层唤醒均未发生显著变化。我们得出结论，与非精英士兵相比，精英士兵在战斗中表现出更高的无氧代谢激活和肌肉力量，但精英组和非精英组在心血管、皮层和肌肉力量表现方面呈现出相同的反应。
