The present invention relates to the technical field of auxiliary training equipment and proposes a user
data analysis method based on a wearable device, comprising: collecting electrocardiogram (ECG) data of an exercise user during training to obtain an ECG sequence, an ECG waveform sequence, and a quasi-period; determining a
frequency curve, obtaining an extreme value pair of the
frequency curve, and then obtaining a frequency extreme value disorder coefficient; obtaining a
fundamental frequency shift coefficient of the ECG data, and then obtaining an intra-cluster fundamental drift deviation coefficient, obtaining a first
correlation coefficient, obtaining an ECG waveform quasi-period deviation coefficient, and then obtaining an ECG waveform disturbance
distortion index; obtaining a first
particle number of the ECG data, denoising the ECG sequence based on the first
particle number, obtaining a denoised ECG sequence, and implementing intelligent analysis of
exercise activity data based on the wearable device based on the denoised ECG sequence. The present invention aims to solve the problem of being unable to dynamically adjust the denoising of training data based on the
exercise state of the exercise user, resulting in poor denoising effect.
