On the Wireless Synchronous Acquisition System of Oxygen Content of Brain and Muscles and Heart Rate in Physical Exercise

In order to explore the brain and heart impulse load effect of the high intensity exercise, the design of wireless equipment for the measuring of instantaneous heart rate and oxygen content of brain or muscles was discussed in this paper. The bi-wave-lengthen near-infrared spectroscopy was used for tissue oxygen measurement. An pair of electrocardiogram electrodes were applied to detect instantaneous heart rate. A pair of wireless MCU(nRF9E5) were applied to collect the data of the tissue oxygen and heart rate. PC was used for recording the curves of the tissue oxygen and heart rate. As a result, a series of data were obtained in the 100m dash and gongfu experiments. As a conclusion, tissue oxygen measurement and sports heart rate wireless real-time acquisition system were very useful for sports monitoring and research work.
