利用连续双波长近红外光技术测量肌肉中血红蛋白含氧量的变化情况, 同时应用运动心率无线实时采集设备, 设计了检测实时肌肉组织血氧含量和瞬时心率实验方案, 对6名健康男性进行了100 m跑同步实测实验。 实验表明, 肌肉组织氧合血红蛋白浓度在100 m跑结束后继续降低, 达到最低值的时刻滞后于运动结束时刻的时间为(6.65±1.10)s； 心率则在运动结束后继续上升, 达到最高值的时刻滞后于运动结束时刻的时间为(8.00±1.57)s。 这些结果显示了双波长近红外光组织氧测试技术和运动心率无线实时采集系统能够正确检测极量强度运动时的血氧参数和心率, 揭示了极量强度运动过程中肌肉中氧运输与消耗的过程及其与心率之间的动力学特征。

Using continuous two wavelength near-infrared technology to detect the variation in the consistency of oxygen hemoglobin in the muscle and the sports heart rate wireless real time collection technology, we devised the real time muscle tissue oxygenation and instantaneous heart rate experiment scheme and implemented it for the process of the 100 m run with two parameters given simultaneously. The experiment shows that the concentration of the oxygen hemoglobin in the muscle tissue continues decreasing after the end of the 100 m run, and the time interval between the moment when the concentration of the oxygen hemoglobin attains the minimum value and the moment when the athletes finish the 100 m run is (6.65±1.10) sec; while the heart rate continues increasing after the end of the 100 m run, and the time interval between the moment when the heart rate attains the maximum value and the moment when the athletes finish the 100 m run is (8.00±1.57) sec. The results show that the two wavelength near-infrared tissue oxygenation detection technology and the sports heart rate real time collection equipment can accurately measure the sports tissue oxygenation and the heart rate in the extreme intensity sport, and reveal the process of muscle oxygen transportation and consumption and its dynamic character with the heart rate in the extreme intensity sport.
