Analysis and Research of Wushu Posture Balance Data Based on Feature Extraction Algorithm

In order to accurately evaluate the balance of Wushu athletes' control of specific movements and postures, a balance evaluation method based on Higuchi fractal dimension analysis was proposed. Firstly, the COP (Center of Pressure) data of athletes' specific movements are obtained through the force test platform, and a time series is constructed. Then, the Higuchi algorithm is used to calculate the fractal dimension of the time series from front to back and from inside to outside. Finally, the balance of action posture is evaluated according to the fractal dimension value. Compared with professional and amateur athletes, the experimental results show that this method can reflect the balance of movements more accurately than traditional methods.
