摘要：Gonelli RGG, Filho EG, Carraro R, Montebelo, MIL, Cesar MC. Comparison of Cardiopulmonary Responses to Treadmill Walking and Running at the Same Speed in Young Women. JEPonline 2011;14(3):53-59. The purpose of this study was to compare the cardiopulmonary responses to treadmill walking and running at the same speed in young women. Eight women between 18 and 24 yrs of age participated in the study. All subjects underwent two submaximal cardiopulmonary exercise tests at 7 km/hr (4.35 mi/hr), one walking and the other running, on separate days. The following variables were found to be higher during running than walking: energy expenditure, oxygen uptake, carbon dioxide output, oxygen pulse, and pulmonary ventilation. No significant differences were found in nonprotein respiratory quotient, heart rate, and ventilatory equivalents for oxygen and carbon dioxide. These results indicate that, at 7 km/hr, running is more indicated than walking for improving cardiorespiratory fitness and body mass in young women.
