摘要

Purpose: The purpose of this study was to compare the oxygen consumption during continuous and intermittent treadmill walking. Methods: Nineteen young and apparently healthy subjects were recruited to participate in this study. Indirect calorimetry (SensorMedics, V(subscript max)29) was used to measure the oxygen consumption during treadmill test. All subjects randomly participated in continuous treadmill walking (106.4 m/min, 30-minute exercise followed by 30-minute rest) and intermittent treadmill walking (106.4 m/min, 10-minute exercise followed by 10-minute rest and repeated 3 times) Paired t-test was used to compare the difference between continuous and intermittent exercise. Results: The mean age of subjects is 23.6±2.3 years. The average exercise intensity is 51.5±10.7% VO(subscript 2max). There is significant difference in total oxygen consumption between continuous and intermittent exercise (t=-4.34, p＜0.0005). There is significant difference in exercise oxygen consumption between continuous and intermittent exercise (t=4.15, p=0.0l). And there is also significant difference in post exercise oxygen consumption between continuous and intermittent exercise (t=-12.01, p＜0.0005). Conclusions: Intermittent exercise could generate more total and post-exercise oxygen consumption than continuous exercise. However, continuous exercise generates more oxygen consumption during exercise period than intermittent exercise.
