Introduction: Cardiorespiratory fitness is the body's ability to resist the state of fatigue when subjected to physical exertion, with emphasis in the military due to the demand of activities that make up the functional performance in military institutions. Objective: The objective of this research was to conduct a comparative study of cardiorespiratory freshmen in the military in five regions of Brazil. Methods: The sample consisted of 764 young people aged between 18 and 21 years old, apparently healthy, submitted preliminary to a health inspection. The evaluation of cardiorespiratory fitness was performed using the Cooper test enabling the determination of VO2max. Results: The young evaluated in the North, South and Southeast had more significant results when compared with the evaluated in the Northeast and Central-West that had less significant results with respect to cardiorespiratory fitness levels. In the Southeast find the best results (average of 3192 meters traveled, indicating VO2max of 59.7 ml.kg.min-1), while in the Northeast the worst results were found (average of 2265 meters traveled, indicating VO2 max.of 39.1 ml. kg.min-1). Conclusion: Cardiorespiratory fitness levels obtained in the five regions were satisfactory, however, no statistical differences were observed, reinforcing the importance of developing public policies, especially in the poorest areas, seeking to facilitate the practice of healthy habits by society, through practice regular physical exercise. Military Organizations in the use of appropriate methodologies to physical training is essential so that the desirable standards are achieved
