Analysis of psychophysiological strain in response to endurance exercise in military personnel.

Background: During exercise, athletes experience a significant elevation in physiological strain, influenced by a multitude of internal and external factors, including physical and environmental conditions. These factors dictate how different organ systems respond to physical activity. This study aims to investigate the psychophysiological strain reactions to endurance training in military male runners. Methodology: A cohort of 75 male military runners, engaging in daily 90 minute exercise routines and agedbetween 20 and 30, was recruited for the study. The study assessed various physiological variables in militaryrunners, encompassing lactate threshold (LT), maximum oxygen uptake (VO2 max), and percentage heartrate reserve (%HRR). Additionally, psychological assessments were conducted using the Brunel Mood Scaleand Borg's Rate of Perceived Exertion. Results: The findings revealed a gradual increase in heart rate (HR) and VO2 max as running intensity escalated. Notably, the runners' perceived exertion rate rose following competitive running events, concomitant with a decrease in their positive mood scale ratings. This trend reflected their disappointment stemming from their performance outcomes. Conclusion: The study highlights that VO2 max and LT serve as robust indicators of male runners' potential. Furthermore, the evaluation of runners' mood and perception of exertion before and after the sprint demonstrated an augmentation in negative emotions post-exercise.
