摘要：The aim of this study was to compare the maximal cardiorespiratory responses between deep water running (DWR) and treadmill running (TR). Five young women performed two maximal tests (DWR and TR), with progressive loads, until subjects’ exhaustion. Oxygen uptake (VO2) and minute ventilation (Ve) were evaluated trough a KB1-C gas analyzer (AEROSPORT) and heart rate (HR), trough a S610 frequencemeter (POLAR). Paired t-test was used, with p < 0.05 (SPSS 13.0). The results obtained in DWR for maximal effort were significantly lower than TR for variables VO2, Ve and HR. This lower behavior probably occurred due the hydrostatic effects from aquatic environment and the different muscular recruitment pattern. It can be concluded that DWR, when compared to TR, in a maximal effort protocol, causes a smaller cardiorespiratory demand for studied variables in young women.
