Measurement of Throwing Multi-Dimensional Force Information of Athlete and Feature Analysis

Digital shot device which can measure the throwing force of shot athlete in real time, is introduced. It is composed of a three-dimensional acceleration sensor and the data collection circuitry. The features of multi-dimensional force information are extracted by fast wavelet transform and the feature vectors are analyzed with gliding shot putting. The application of digital shot and the signal processing method is benefit for the study of the shot athlete’s throwing motion. It provides the theoretical basis for analyzing the motion technology.
