Abstract
Thirteen subjects (mean [+ or -] SD age: 21.8 [+ or -] 2.6 yrs) performed an incremental cycling test and 4, 8-min submaximal rides (65 to 80% of V[O.sub.2] peak) to: (a) compare power outputs and relative intensities that corresponded to the gas exchange threshold (GET), ventilatory threshold (VT), respiratory compensation point (RCP), physical working capacity (PWC) at oxygen consumption PWCV[O.sub.2], heart rate (PWCHRT), and rating of perceived exertion (PWCOMNI) thresholds; and (b) examine the relationships among the fatigue thresholds and the exercise intensity domains. The RCP (184 [+ or -] 47 W) was significantly (P [less than or equal to] 0.0033) greater than the GET (142 [+ or -] 38 W), VT (143 [+ or -] 40 W), PWCV[O.sub.2] (106 [+ or -] 34 W), PWCHRT (108 [+ or -] 34 W), and PWCOMNI (112 [+ or -] 34 W). The GeT and VT were significantly greater than the PWCV[O.sub.2], PWCHRT, and PWCOMNI, but there were no differences among the PWCV[O.sub.2], PWCHRT and PWCOMNI. These findings suggest that the PWCV[O.sub.2], PWCHRT, and PWCOMN fell within the moderate intensity domain, and share a common physiological mechanism that was different from those associated with the GET, VT, and RCP. Key Words: Exercise Intensity, Power Output, Perception of Effort, Aerobic Evaluation
