ABSTRACT
Introduction:
Sports recognition technology gradually mature. Among them, wearable sensors have attracted wide attention because of their accurate recognition.
Objective:
The following squats are used as an example to determine whether CNN and EMG signals determine whether functional motion is standard.
Methods:
Based on the FMS of EMG, 80 students of the same grade are randomly selected from the Physical Education School of XX University for the experiment and the results are verified.
Results:
The results show that the GBC can classify the EMG signal of the three functional movements more accurately, and the classification accuracy rate of squat, stride, and straight lunge squat is 91%, 89%, and 90%, respectively. The decision tree has a good ability to judge whether the functional movement is standard or not, and the accuracy of judgment can reach more than 98%. In conclusion, EMG-based FMS can effectively detect early sports injuries and plays a good role in reducing sports injuries.
Conclusions:
The classification effect of the squat is the most obvious, reaching 91%, and its recognition ability is the strongest. Level of evidence II; Therapeutic studies - investigation of treatment results.
