Oxygen uptake and blood flow of the lower limb in maximal treadmill and bicycle exercise

Abstract
The present study was undertaken to compare the effects of maximal treadmill and bicycle exercise on maximum oxygen uptake and blood flow in the lower extremity. Mean maximum oxygen uptake in maximal treadmill exercise was higher than that in bicycle exercise (pp< 0.001). Blood flow in the thigh immediately after bicycle exercise was significantly higher than that in the calf (pp<0.05). From these results, it is suggested that the lower maximum oxygen uptake observed during bicycle exercise as compared with treadmill exercise seems to be due to a lower blood flow in the lower limb.
