This study was designed to determine if any differences existed in the perception of exertion between Type A and Type B females. Of the 316 male and female college students completing the JAS - Form T, 17% were identified as Type A. A total of 38 females (Type A= 17, Type B = 21) completed a maxVO2 test and a series of submax tests. A treadmill test involving a walking protocol was done to determine each S's maxVO2. A regression equation was then used to determine workloads of 50%, 65%, and 80% for each s. Ss underwent a submax test involving these 3 workloads while V02 , HR, and RPE's utilizing the Borg Perceived Exertion scale were determined. Independent t tests showed no sig (p>.05) diff in age, height, weight, maxVO2 , maxVE, or maxHR between groups. For the submax exercise, both groups worked at equal intensities for all 3 workloads, since VO2s and HR 1s showed no sig (p>.05) diffusing a two-way ANOVA. RPEs at all 3 workloads were analyzed utilizing a two-way ANOVA, and were not sig (p>.05) diff between groups. It was concluded that there were no differences in the perception of exertion between Type A and Type B females working at similar intensities.
