dc.description.abstractCaffeine is one of the ergogenic substances most used by warfighters in current operation areas, but the effect on the organic response and operational performed is already poor knowledge. This research aimed to study the acute effect of 400 mg of caffeine monohydrate on the psycho-physiological response and rifle marksmanship of warfighters during a close quarter combat simulation. We analysed parameter of heart rate, blood lactate, cortical arousal, state anxiety and marksmanship of 20 Spanish Army veteran warfighters before and after a close quarter combat simulation in a double-blind procedure, also a correlation analysis was conducted between all the study variables. Marksmanship of warfighters did not improve with the caffeine ingestion, but it produced an increase in blood lactate concentration (caffeine: 1.9 ± 0.5 vs. 9.2 ± 1.1 mmol.l−1; placebo: 1.8 ± 0.7 vs. 6.9 ± 2.2 mmol.l−1), cortical arousal (% of change: caffeine: 2.51; placebo: −1.96) and heart rate (caffeine: 80.0 ± 7.2 vs. 172.9 ± 28.2 bpm; placebo: 79.3 ± 6.4 vs. 154.0 ± 26.8 bpm). In addition, higher heart rate values correlated negatively with marksmanship in close quarter combat. We concluded that caffeine intake did not improve the warfighters rifle marksmanship in close quarter combat possibly due to the increase in the physiological responsees_ES
dc.description.abstractLa cafeína es una de las sustancias ergogénicas más utilizadas por los combatientes en las áreas de operación actuales, pero el efecto sobre la respuesta orgánica y la operativa realizada es ya de bajo conocimiento. Esta investigación tuvo como objetivo estudiar el efecto agudo de 400 mg de monohidrato de cafeína sobre la respuesta psicofisiológica y la puntería de los combatientes durante un simulacro de combate. Analizamos el parámetro de frecuencia cardíaca, lactato sanguíneo, excitación cortical, ansiedad de estado y puntería de 20 combatientes veteranos del Ejército español antes y después de un simulacro de combate en un procedimiento de doble ciego, y también se realizó un análisis de correlación entre todas las variables del estudio. La puntería de los combatientes no mejoró con la ingesta de cafeína, pero produjo un aumento en la concentración de lactato en la sangre (cafeína: 1.9 ± 0.5 vs. 9.2 ± 1.1 mmol.l − 1; placebo: 1.8 ± 0.7 vs. 6.9 ± 2.2 mmol.l −1), excitación cortical (% de cambio: cafeína: 2.51; placebo: −1.96) y frecuencia cardíaca (cafeína: 80.0 ± 7.2 vs. 172.9 ± 28.2 bpm; placebo: 79.3 ± 6.4 contra 154.0 ± 26.8 bpm). Además, los valores más altos de la frecuencia cardíaca se correlacionaron negativamente con la puntería en el combate a corta distancia. Llegamos a la conclusión de que la ingesta de cafeína no mejoró la puntería del rifle de los combatientes de guerra en el combate cuerpo a cuerpo posiblemente debido al aumento de la respuesta fisiológica.es_ES
