摘要:: 本研究基于三轴加速度传感器系统和心率采集系统，通过征集98名志愿者，进行269次Bruce-Q运动实验，同步采集志愿者运动时的X（左右）、Y（上下）、Z（前后）三轴向加速度数据和心率值，建立三轴加速度运动—心率数据库；分析实验结果可知，人体各个轴向运动加速度与心率线性相关，运动后心率恢复具有呈指数下降的规律性；结果表明，在运动时Y（上下）轴、Z（前后）轴比X（左右）轴更能反应人体真实运动状态。

Abstract:: Based on the 3-axis accelerometer system and the heart rate acquisition system, we conducted 269 Bruce-Q exercise experiments by collecting 98 volunteers, and simultaneously collected 3-axis acceleration data and heart rate values of X (left and right), Y (upper and lower), and Z（front and rear) axis during volunteer exercise to establish a 3-axis acceleration motion-heart rate database. The experimental results showed that the human body′s various axial motion acceleration was linearly correlated with heart rate. The results show that Y (upper and lower) axis and Z (front and rear) axis can better reflect the real motion state of human body than X (left and right) axis.
