Dicho alcaloide permite potenciar el rendimiento tanto físico como cognitivo. Estas cualidades hacen de la cafeína un candidato ideal para mejorar el rendimiento de las unidades militares en despliegue.  Objetivo: revisar la evidencia científica existente acerca de los beneficios de la cafeína, en su diversidad de presentaciones, y su aplicación en misiones militares con condiciones estresantes o desfavorables.  Materiales y métodos: se revisaron aquellos estudios acerca de los beneficios de la cafeína con mayor relevancia y cuyos resultados fuesen robustos, reproducibles y estuviesen contrastados, utilizando para ello las bases de datos científicas PubMed, Scielo, Google Scholar y Elsevier.  Discusión: el consumo de cafeína en la población militar es común y variado. La diversidad de modalidades de presentación, disponibles para su utilización en despliegues militares, favorece el uso de este alcaloide como ayuda ergogénica. En condiciones desfavorables, la cafeína ha demostrado incrementar el rendimiento del efectivo militar al aumentar significativamente su tiempo de actividad.  Conclusiones: cuestiones como el aumento de la fatiga física por deprivación del sueño o el estrés cognitivo causado por largos periodos de tiempo en actividad pueden reducirse con el uso de la cafeína. Consumo de cafeína de 3-6 mg/Kg de peso corporal/día ha demostrado ejercer la totalidad de sus efectos beneficiosos.]]></p></abstract>

This alkaloid has the ability to enhance both physical and cognitive performance. These features make caffeine an ideal candidate for the improvement of deployed military units&#8217; performance.  Objective: To revise preexisting scientific evidence concerning the beneficial properties of caffeine, regardless of its formulation, and its utilization in military missions carried out under stressing or unfavourable conditions.  Materials and methods: Only studies deemed the most relevant and whose results were robust, reproducible and contrasted enough were taken into consideration. The scientific databases consulted include PubMed, Scielo, Google Scholar and Elsevier.  Discussion: Caffeine consumption among military population is frequent and diverse. The wide variety of formulations available for its employment in military missions promotes the use of this alkaloid as a ergogenic support. Under unfavourable conditions, caffeine has been proven to enhance significantly the performance, which improve the operative time of military units.  Conclusion: Caffeine could be able to reduce the consequences of sleep deprivation, such as physical fatigue, or the mental strain caused by long periods of activity. The ideal caffeine consumption would be of 3-6 mg/kg body weight/day, since this dosage has been proven to display all the beneficial effects of caffeine.]]></p></abstract>
