%X the purpose of the present study was to assess the differences in ratings of perceived exertion (rpe) and oxygen uptake (vo2) behavior during water and land-based exercise, performed in the exercise intensity of the first ventilatory threshold between pregnant and non-pregnant women. seven pregnant (gestational ages between the 27th and 30th week) and seven non-pregnant women performed two continuous cycle ergometer tests (water and land-based) at the first ventilatory threshold intensity. during all sessions, respiratory gases were collected with a portable aerosport kb1-c mixing box gas analyzer. a pneumotach was used with a neoprene mask. heart rate (hr) measurements were obtained with a polar f1. data were collected every 20s. rpe on borg scale from 6 to 20 was derived at the end of the exercise. one-way anova was applied for repeated measures using the post-hoc bonferroni test (p<0.05). no significant differences were found in vo2 or rpe when comparing water with land-based exercise. in the same way, no significant difference was found between pregnant and non-pregnant subjects. we suggest that rpe can be used for water and land-based exercise prescription on cycle ergometer at the intensity of first ventilatory threshold, for both pregnant and non-pregnant women.
