Respuesta orgánica en una simulación de combate

background and objectives: analysis of organic response in combat is a bit field of study specifically studied in specific literature, for this reason the objective of this work is to analyze the effect of a combat simulation in the organism of soldiers. material and methods: we analyzed the critical flicker fusion frequency (cfff) as a means of detecting fatigue of central nervous system (cns), leg explosive strength, isometric strength, blood lactate and rating of perceived exertion in 20 soldiers before and after performing a combat simulation. results: after combat simulation, soldiers showed a significant increase (p<0,05) in lactate levels (2,57±0,62 mmol/l vs. 4,92±2,18 mmol/l) and isometric strength and a decrease in legs explosive strength. cfff values decreased, showing signs of fatigue of cns. conclusions: combat simulation was highly stressful, showing signs of fatigue of the cns, are carried out in anaerobic conditions, despite the low speed o execution, and the subjective perception of effort does not correspond to the organic response obtained. these data could use to adapting current training systems for current missions in combat zones.
