![]() ![]() The average predicted values of VO2max= 35.63 ± 2.2 ml/kg/min. As for the Bruce protocol, maximum oxygen consumption (VO2max), time to fatigue, blood pressure, rate of perceived exhaustion (RPE), and maximal heart rate (HRmax) were measured. ![]() (RHR), resting blood pressure (BP), and the heart rate after the step test (HRstep) were recorded. The subjects’ respective VO2max were compared between their step test and Bruce exercise. The Bruce protocol is a maximal exercise test where the speed and incline progressively increase at every stage (3 minutes) until the subject reaches fatigue. Each subject performed a QCT and a Bruce protocol graded exercise test on a treadmill on non-consecutive days. METHODS: Six women (W age 19.7 ± 1.6 yrs) of the UTA student population volunteered to participate in this study. PURPOSE: The purpose of this experiment was to determine the reliability of the Queen’s College 3-minute step test as a predictor of VO2max for college aged healthy women. Variables measured during this study are heart rate (HR), rate of perceived exertion This study was conducted to determine the applicability of the QCT in young healthy women in predicting VO2max. Despite claims that the QCT is a valid measure of VO2max, its validity in young healthy women has been contested (Chatterjee 2003). A lower maximal oxygen capacity is a strong predictor of cardiovascular disease. VO2max is an internationally accepted reference standard for assessing cardiorespiratory fitness (Shepard 1968). This test can also be used to estimate maximal oxygen consumption (VO2max). The test consists of 3 minutes of stepping up and down on a 15-inch step at a set rate of 22 steps/min. INTRODUCTION: The Queen's college step test (QCT) is a submaximal exercise test that is used to measure cardiorespiratory fitness. ![]()
