Monitoring method and monitoring device of motion data index

The invention discloses a monitoring method and a monitoring device of motion data index. The monitoring device comprises a portable monitoring terminal, and the monitoring terminal comprises an acceleration sensor, a processor and a display device; the display device is electrically connected with the processor, for displaying the monitoring index data output by the monitoring terminal, and the monitoring index data comprises left and right oscillation power; the acceleration sensor can feed back the left and right accelerations relative to a monitored object to the processor, and the processor can calculate the left and right oscillation power consumed by each step of the monitored object according to the left and right accelerations fed back by the acceleration sensor; and it can be seen from the above that the above monitoring device can provide runners with oscillation power parameters including left and right oscillation power, so as to provide runners with more professional running posture evaluation d
