“…Cortical arousal was assessed using the critical flicker fusion threshold (CFFT). An increase in CFFT indicates heightened cortical arousal and improved information processing capabilities, while a decrease suggests reduced processing efficiency and central nervous system fatigue [ 4 , 10 , 11 ]. For this assessment, subjects were positioned in front of a viewing chamber (Lafayette Instrument Flicker Fusion Control Unit Model 12021), designed to mitigate external factors affecting CFFT readings.…”

“…Consequently, scholarly research into the physiological and psychological ramifications of combat stress has been extensive, yielding a nuanced comprehension of its impact on soldiers in combat scenarios. A synthesis of pertinent literature [ 1 , 2 , 3 , 4 ] reveals that combat stress exerts a significant influence on the sympathetic nervous system, manifesting in elevated metabolic rates, increased muscular tension, and heightened cardiovascular activity, coupled with a decrease in cortical arousal. These physiological adaptations, while evolutionarily advantageous for immediate survival responses, have been documented to adversely impact critical higher-order cognitive functions essential in combat, such as decision-making and memory retention [ 5 ].…”

This study explores the psychophysiological responses and subjective exertion experiences of soldiers in simulated hand-to-hand combat, aligning these findings with established physiological benchmarks. Active military personnel were monitored for heart rate, blood lactate levels, subjective exertion, cortical arousal, and muscle strength during combat scenarios. The results showed significant increases in heart rate and blood lactate, indicating intense cardiovascular demands and a reliance on anaerobic energy systems. Contrary to these physiological changes, soldiers reported lower levels of exertion, suggesting a possible underestimation of physical effort or individual differences in perception and mental resilience to stress. Notably, a decrease in cortical arousal post-combat was observed, potentially signaling cognitive function deficits in decision-making and information processing in high-stress environments. This decline was more pronounced than typically seen in other high-stress situations, highlighting the unique cognitive demands of hand-to-hand combat. Additionally, an increase in muscle strength was noted, underscoring the physiological adaptations arising from intensive combat training. These findings provide valuable insights into the psychophysiological effects of hand-to-hand combat, emphasizing the complex interplay between physical exertion, cognitive function, and stress response in military contexts. The study underscores the need for comprehensive training strategies that address both physical and psychological aspects to enhance combat readiness and decision-making under stress.

Impact of Physical Fatigue State on Military Mission Oriented Obstacle Course Timing Performance

Military oriented obstacle course timing has been used to evaluate different clothing and individual equipment designs and configurations. However, it is unclear if completing operationally relevant fatigue tasks prior to course completion will highlight differences in physical performance due to wearing different equipment configurations. Fifty-one experienced, active duty soldiers completed the course in a rested and fatigued state in three equipment configurations of varying weights and encumbrance. A controlled paced (3 mph) three mile foot march was used to induce fatigue. Time to complete the whole course and each of the 11 obstacle segments were measured. Fatigue state and configurations were found to be significantly different for total course time, where the fatigued moderate configuration was similar in performance to the fully loaded rested configuration. Similar results were also seen for the individual obstacle segment time measurements; however the walls and casualty drag obstacles may be slightly less sensitive.
