We hypothesized that, during exercise, substantial heterogeneity of muscle hemoglobin and myoglobin deoxygenation(HHb) dynamics exists. The purpose of this study was to measure the responses of the matching of O_2 delivery and O_2 utilization in humans. The present results suggest that regional heterogeneity in the magnitude and temporal profile of muscle deoxygenation is a consequence of differential responses of the matching of O_2 delivery and O_2 utilization. However, there was a poor relationship between the speed of overall muscle VO_2 kinetics and the heterogeneity of HHb.

我们假设，在运动过程中，肌肉血红蛋白和肌红蛋白脱氧（hbb）动力学存在实质性的异质性。本研究的目的是测量人体对氧气输送和利用的匹配反应。本研究结果表明，肌肉缺氧程度和时间分布的区域差异是由于氧气输送和氧气利用匹配的差异反应造成的。然而，肌肉VO_2整体动力学速度与hbb异质性之间的关系不明显。
