| Relative to the Olympic Games, winter Olympic Games is not a known by the Chinese a grand sporting event.Short track speed skating movement is a project will not be noticed, the penetration rate is at a relatively low level, engage in professional sports teams and the national team, but in the winter Olympics games, short track speed skating is very popular as well as the system, including athletes training game, short track team construction, technical research, such as health care or a set of more perfect operation system.This study is part of the technical research, also from belong to the state general administration of sports public relations of the2014winter Olympics part of scientific research and service projects. Han Yu tong is national culture of a female, her performance is outstanding, has repeatedly won the champion in the World Cup and the national competition, included in the2014Olympic winter games in sochi bullpen, China’s short track team to see the importance of her.This article mainly USES the research method:adopt the Netherlands XSENS MVN BIOMECH human body model (inertial motion capture system software)3d sensor sensing method of short track speed skating athletes in China five laps bend technology in the training of the field to collect relevant data, short track speed skating athletes in China when making the bending technology, the technology of each index is analyzed, including the head and left shoulder, shoulder (or so), elbow (or so), hips (or so), knees (or so), feet (about) this11joints, it is concluded that the athletes into the bending technology and joint angular velocity of each joint Angle of biomechanical data.By use of Excel and SPSS17.0statistical software for the mean and standard statistical analysis and processing, organizing Chinese short track speed skating athletes Han Yu tong into the bending and the technical characteristics of the relevant data, and made a chart. Research results show that:1. Holland XSENS MVN BIOMECH human body motion capture system, using the three dimensional inertial sensor induction method, inertial sensors embedded magnetometer, gyroscope and accelerometer, without external capture device for the sensor itself dynamic three-dimensional coordinates, this is the first time to use in short track speed skating all of. The difference of this system is that it can obtain in the three-dimensional space of each joint Han Yutong whole sliding indexes, it is soft and can not do, it can measure the long distance, the calibration is simple and convenient, small data error.2. The Han Yu tong entry the technical features of analysis mainly from the following several categories described, entry point in the previous step, step after entry point and into the corner point head, left shoulder, shoulder (or so), elbow (or so), hips (or so), knees (or so), the Angle of the feet (or so) and the change of the angular velocity. Changes in the scope of the angle in the three-dimensional space are analyzed, and through the change of the angle of the direction of movement joint three-dimensional space. At the same time will also be angular velocity as the research target, the movement in the form of3D spatial data that joint angular velocity, which plays an important role in establishing the bending action model, also makes the research of the bending technology more specific.3. From the above several groups of data to Han Yu tong into the head in the process of bending, the left shoulder, shoulder (or so), elbow (or so), hips (or so), knees (or so), feet (or so) describe the change of the Angle and angular velocity analysis, overall no too big differences of movement, the approach to maintain a good body posture, movement is more stable. Corners before each joint angle velocity change is gradually accelerating trend, Ruwan step joint angle velocity is more complicated, in before bending step and Ruwan step joint angular velocity difference. |
