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（HHb）动态存在显着的异质性。本研究的目的是测量人类 O_2 输送和 O_2 利用匹配的反应。目前的结果表明，肌肉脱氧的幅度和时间分布的区域异质性是 O_2 输送和 O_2 利用匹配的差异反应的结果。然而，整体肌肉 VO_2 动力学速度与 HHb 异质性之间关系较差。
