Abstract
It seems that CrossFit workouts due to its effect on strength, endurance, and cardiovascular conditioning is suitableto be used in military training. A military exercise or war game is the employment of military resources in training for military operations, either exploring the effects of warfare or testing strategies without actual combat. This study aimed to investigate the effect of simulated CrossFit exercise of the military operation on cardiovascular indicators and the physical readiness of military forces. This research is in the manner of experimental studies through a pre- and posttest design. Twenty-four male military forces (age: 21.07 ± 1.6; weight: 74.6 ± 12.1 kg; height: 175.1 ± 6.28; and body mass index (BMI): 23 ± 3.3 kg/m2) were randomly divided into two groups of CrossFit and control. The CrossFit group had three training sessions per week for four weeks. The exercise of the CrossFit group included metabolic conditioning, weight-lifting, and gymnastics, while the control group also did their usual physical activity. The results show that in the CrossFit group the means of BMI, fat mass, heart rate, systolic, and diastolic blood pressure have significantly decreased () compare to pre-test, while, the amount of VO2max, maximal power to weight, average power to weight, and the army physical fitness test (APFT) score improved significantly in CrossFit group compared to the pre-test (). Compared to the control group at post-test, crossFit significantly increase fat present, BMI, VO2max, maximal power/body weight, and power/body weight () and significantly decreased systolic blood pressure, diastolic blood pressure, and heart rate (). Our results suggested that performing four weeks of the simulated CrossFit exercises of the military operation causes improving the cardiovascular indexes, and physical readiness of military personnel.
期刊介绍：
''Comparative Exercise Physiology'' is the only international peer-reviewed scientific journal specifically dealing with the latest research in exercise physiology across all animal species, including humans. The major objective of the journal is to use this comparative approach to better understand the physiological, nutritional, and biochemical parameters that determine levels of performance and athletic achievement. Core subjects include exercise physiology, biomechanics, gait (including the effect of riders in equestrian sport), nutrition and biochemistry, injury and rehabilitation, psychology and behaviour, and breeding and genetics. This comparative and integrative approach to exercise science ultimately highlights the similarities as well as the differences between humans, horses, dogs, and other athletic or non-athletic species during exercise. The result is a unique forum for new information that serves as a resource for all who want to understand the physiological challenges with exercise.
