本研究旨在比较脚踏车运动和脚踏车运动对下肢最大摄氧量和血流量的影响。最大跑步机运动的平均最大摄氧量高于自行车运动（p<0.001）。在跑步机和自行车最大运动后立即测量的大腿血流量平均值和标准误差分别为39.1±4.0和44.2±2.8 ml/100 ml·min，差异无统计学意义。然而，观察到两种运动后立即测量的小腿血流量有显著差异（p< 0.001）。自行车运动后大腿的血流量明显高于小腿（p<0.001），而跑步机运动后大腿和小腿的血流量差异很小，没有统计学意义。腿部血流量，大腿和小腿血流量的平均值加在一起，作为下肢血流量的指标。结果发现，跑步机上的腿部血流量明显高于自行车运动（p<0.05）。从这些结果来看，与跑步机运动相比，在自行车运动中观察到的最大摄氧量较低似乎是由于下肢的血流量较低。
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 (p<0.001). Mean values and standard errors of blood flow measured immediately after maximal treadmill and bicycle exercise in the thigh were 39.1±4.0 and 44.2±2.8 ml/100 ml·min, the difference not being significant. However, a significant difference in blood flow in the calf measured immediately after both types of exercise was observed (p< 0.001). Blood flow in the thigh immediately after bicycle exercise was significantly higher than that in the calf (p<0.001), whereas the difference between thigh and calf in treadmill exercise was small and statistically not significant. Leg blood flow, the average value of blood flow of the thigh and calf added together, was used as an index of blood flow in the lower extremity. It was found that the leg blood flow was significantly higher on the treadmill than with bicycle exercise (p<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.
