摘要：

The purpose was to assess the validity of predicting peak oxygen uptake ((V) over dotO(2)peak) from Ratings of Perceived Exertion volitional exhaustion. During GXT, oxygen uptake (VO2) and RPE were measured Individual linear regressions between (V) over dotO(2) and RPE < 15 were extrapolated to RPE 20 in order to predict (V) over dotO(2)peak Actual and predicted VO(2)peak were not significantly different (13.9 +/- 3.0 vs 14.2 +/- 3.3 ml kg(-1) min(-1), respectively, p = 26) The Pearson product moment correlation between actual and predicted (V) over dotO(2)peak was high (r = 0 82). The 95% limits of agreement analysis on these values (bias +/- 1 96SD) was -0.3 +/- 3.7 ml kg(-1) min(-1). Results suggested that RPE <= 15 elicited during a sub-maximal GXT provides accurate VO(2)peak prediction. Therefore, it is not necessary to perform GXT to voluntary exhaustion to determine VO(2)peak in obese women.
