Abstract
The purpose of this investigation was to identify a perceptually based warning zone to anticipate termination of Bruce treadmill tests. Apparently healthy adult women ( n = 116) and men ( n = 55) participated. The time to test termination was measured from the point during the treadmill test at which participants estimated a rating of perceived exertion of 12, 13, 14, 15, 16, and 17 using the Borg 6–20 scale to specify the rating of perceived exertion which was less than or equal to one exercise test stage. Women exercised for 141.9 ± 99.2 sec. after reporting a rating of perceived exertion of 14. Men terminated the treadmill test 120.1 ± 80.0 sec. after estimating their rating of perceived exertion to be 15, indicating volitional test termination will occur before the next exercise stage is completed. Accurate and timely prediction of test termination using ratings of perceived exertion may enhance the safety of exercise tests administered to apparently healthy adults and facilitate obtaining endpoint measures upon which to prescribe exercise intensity.

Abstract
The purposes of this study were to identify a zone of normality based upon ratings of perceived exertion (RPE) and compare the RPE of women with coronary artery disease to this zone. 45 healthy women (34.8 ± 9.1 yr.) completed a Bruce treadmill test. RPE were estimated during the last minute of each workload. The zone of normality was established as the 95% confidence interval spanning the average line when RPE was regressed against MET. 51 women (66.6 ± 9.3 yr.) with coronary artery disease completed a symptom-limited treadmill test. 31 of the women with coronary artery disease were taking beta blockers. RPE were compared to the RPE/MET relation of the zone. 57% of the women with coronary artery disease estimated RPE above the zone during the treadmill test. RPE responses above the zone of normality indicate an elevated perceptual strain for a given energy expenditure (i.e., MET). The zone of normality might be used as an aid in discriminating between normal and abnormal RPE responses during graded treadmill tests by women with coronary artery disease.
