Leaving of this verification, she intends in this research to verify physiologic variables. Revising to the literature on present study, they proposed several treatises specifying the reactions and adaptations so much physiologic as behaviors happened in the organism during immersion. The model of the descriptive research of the type was followed Survey, where they participated divers of the Navy of Brazil, of the masculine sex, ap- prentices of physical activities, in a total of 9, among 20 and 40 years (x=28 +/- 4.3). They executed test effort at the level of the sea and the 18 depth meters (pressurized in hiperbaric chamber), being verified the variables proposals in exercise. The sample was homogenized through the calculation of percentile of fat, of the perimetria and test chosen neuromotores of performance. The results were analyzed in the signifi- cance level p < 0.05, established as parameter in this study. The heart rate p=0.1468 > 0.05, it denotes not to exist significant difference among the verified atmospheres. The maximum consumption of oxygen p=0.00013 < 0.05, and the vital capacity p=0.0126 < 0.05, they denote to exist significant differences among the atmospheres. Finally, through the obtained data, was ended that the environment influence directly the consumption of oxygen and the vital capacity. As the heart rate, direct influence was verified provoked by intensity and duration of the independent exercise of the atmosphere. This checks the importance of knowing the appraised physiologic reactions and revised in the literature, as essential components of the performance, confirming the need to create programs of physical training adapted to the divers.
