| Abstract: | IIn order to meet the needs of studying on three-dimensional space technical characteristics of the human body in the training, a set of triaxial acceleration transducer system is developed. The system consists of upper bit and lower bit, the lower bit consists of the acceleration transducer, sense picking unit, data processing unit, power monitoring and protection unit and the wireless transmission unit, upper bit consists of the data acquisition and analysis software. The system has the function of four-channel synchronal sampling, combined with sync videos, which can collect and analyze limb arthrosis of athletes, exercisers of competitions and other technical components with parameters of kinesiology and dynamics in a real time. In physical training, frequently-used barbell squat training belongs to the field of experimental applications, technical analysis of barbell squat training for speed skating and weightlifting, by analyzing the data which is collected by triaxial acceleration transducer, find out the technical characteristics and differences of barbell squat in differenct events, providing a studying foundation for the development and releted application of acceleration transducer system. |
