Purpose: The purpose of this study was to examine the relationship among heart rate, energy consumption, and the ratings of perceived exertion (RPE) in female college students during stepping exercise. Method: Ten healthy females, age 18 to 29, with regular exercise habit volunteered in this study. The subjects did a progressive maximal test in a 10 inches stepper till their heart rate reached 85% of their own maximal heart rate. The progressive test had fours stages, 2 minutes each, with 4 different speeds, which is 50, 60, 80, and 100 steps per minute. Three days later, the subjects were asked to perform a combination of stepping exercises with different speeds and step heights. During the stepping exercise, subjects' heart rate, RPE, oxygen consumption, and energy consumption were recorded in a one-minute interval. Result: Under two different height stepper exercises, heart rate, RPE, and energy consumption (include to oxygen consumption convert value and the value measured by RT3) are highly correlated from each other (r>0.9, p<.05). Conclusion: During stepping exercise, heart rate, RPE, and energy consumption measured by RT3 are options that could be used to represent energy consumption.
