Design, manufacturing and test of a wearable device to monitor athlete's body movement

Image processing devices have always been used to describe quantitative body's movements, which in addition to being costly, have to be used in specific conditions. Therefore, in order to reduce these limitations and examine body movements, this article introduces a device based on wearable sensors. The device is designed and built from a number of wireless modules that are easy to use in real-world environments with no limitation. In this method, a quantitative description of movement is made by wireless modules and is performed by these data that collected with these modules. In order to analyze the data that was extracted from an athlete's body movements with this wearable sensor, these data are simulated on Matlab and some of its kinematic and kinetic parameters have been studied. Then, at the end of this paper the quality of movement of a professional athlete and a beginner athlete were compared and the result is shown. Kinematic and dynamic analyzes on the above activities showed the following results The movements are generally correctly recorded. The kinematic analyzes performed for the various movements were consistent with the facts. For example, the kinematic analysis of the recorded movement motion showed that the coach movement was more beautifully performed, and this was evident qualitatively during the movement.
