MOREIRA, Carlos Alberto and DANTAS, Estélio Henrique M.. Maximum aerobic power, heart rate, and vital capacity in normo and hyperbaric environments. Rev Bras Med Esporte [online]. 1999, vol.5, n.5, pp.183-186. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86921999000500005.
This paper aims at studying physiological variables related to diving. The literature review on the subject found both physiological and behavioral reactions developed by the organism during diving. This research follows the survey model and investigated 9 divers belonging to the Brazilian Navy. They are all male; mean age 28 ± 4.3 years; weight 76.7 ± 8.32 kg; height 173.8 ± 6.33 cm. All subjects were evaluated using various physiological parameters, determined for sea level study (normobaric environment) and for 18 meters of depth (hyperbaric environment), pressurized in hyperbaric chamber, following variables proposed for exercises. The significance value established as a parameter is p < 0.05. Heart rate (p = 0.1468; > 0.05) showed there were no significant differences between the verified environments. Maximum oxygen consumption (p = 0.00013; < 0.05) and the vital capacity (p = 0,00126; < 0.05) denoted significant differences between environments. The data confirmed the importance of knowing the physiological reactions evaluated and reviewed in the literature as essential components of performance with emphasis upon the physiology of hyperbaric exercise.
