Posture identification method and device

The embodiment of the invention discloses a posture recognition method and device. The method comprises the following steps: acquiring a q-axis current value generated when a motor drives the treadmill; according to the q-axis current value, characteristic data of the treadmill in each current period is determined, the characteristic data of the treadmill comprises multiple characteristic moments and q-axis current values corresponding to the multiple characteristic moments, and the multiple characteristic moments form one current period in which the motor completes the load sudden change process; according to the heavy load stability starting moment and the heavy load stability ending moment in the multiple characteristic moments, the posture of the sporter on the running machine is recognized. Through the method and the device, the technical problem that the detection cost is relatively high due to the fact that the posture of a sporter on a running machine is detected by using a sensing device of the runni
