Nineteen physically active men and women (age range 19-23years) volunteered to participate in two graded exercise tests to volitional exhaustion to measure $$\dot{V}\rm O_2$$ max ( $$\dot{V}\rm O_2$$ maxGXT), at the beginning and end of a 2-week period, and four incremental, perceptually regulated tests to predict $$\dot{V}\rm O_2$$ max in the intervening period. Effort production tests comprised 2×2-min and 2×4-min bouts on a cycle ergometer, perceptually regulated at intensities of 9, 11, 13, 15 and 17 on the Borg 6-20 rating of perceived (RPE) scale, in that order. Individual linear relationships between RPE and $$\dot{V}\rm O_2$$ for RPE ranges of 9-17, 11-17 and 9-15 were extrapolated to RPE 20 to predict $$\dot{V}\rm O_2$$ max. The prediction of $$\dot{V}\rm O_2$$ max was not moderated by gender. Although, $$\dot{V}\rm O_2$$ max estimated from RPE 9-17 of trial 1 of the 2-min protocol was significantly lower (P<0.05) than $$\dot{V}\rm O_2$$ maxGXT and $$\dot{V}\rm O_2$$ max predicted from the 4-min trials, the $$\dot{V}\rm O_2$$ max predicted from trial 2 of the 2-min protocol was a more accurate prediction of $$\dot{V}\rm O_2$$ maxGXT across all trials. The intraclass correlation coefficient (R) was also higher between $$\dot{V}\rm O_2$$ maxGXT and $$\dot{V}\rm O_2$$ max predicted from trial 2 of the 2-min protocol compared to both trials in the 4-min protocol (R=0.95, 0.88 and 0.79, respectively). Similar results were observed for RPE ranges 9-15 and 11-17. Results suggest that a sub-maximal, perceptually guided, graded exercise protocol, particularly of a 2-min duration, provides acceptable estimates of maximal aerobic power, which are not moderated by gender.
