摘　　要：应用近红外光谱技术监测递增强度运动中局部肌氧变化特征,分析探讨人体骨骼肌内氧合血红蛋白含量相对变化的拐点与呼吸商拐点之间的关系,比较两者在出现时间上的先后及其变化规律,分析它们的不同步生理机制。以期在递增强度运动训练中为教练员提供新的监测指标,为训练内容的安排与制订提供理论和实践的可行性参考依据。The article performs a study on the relative change between inflection points of respiratory quotient （RQ） and HbO2 in skeletal muscle during the process of increased intensity sports, in which the occurrence priority and interval regularity is compared based on time, and the physiological mechanism of synchronisms is analyzed. The results show that the inflection point of RQ is relatively changing to AHbO2. That means there is a time delay in RQ. The delay in VO2 and VCO2 relative to HbO2, which is affirmed in the single - factor variance analysis test, is do exist.
