Minority Traditional Sport Athletic Event--Shoe Racing Technique Analysis

Board-shoe Racing as an emerging from Guangxi ethnic traditional sports, with the country and the society’s support, has been rapid development in a few years. Its athletics, education and entertainment and many other functions have been the affirmation of people. The project spread throughout the country over20provinces and cities, competition result substantial increase year by year. Under the background of board-shoe speeder running, technology analysis has important significance.The study object in this study is Chongqing men’s1team, Guizhou men’s2team, Beijing men’s1team and technical style unique to Qinghai men’s1team who won the excellent performance in the Ninth National Traditional Ethnic Minority Sport Meet Board-Shoe Racing Competition. Mainly useing photography method and image analysis method, to analyze technology with kinematics. Elucidation of the four teams technological characteristics and the angle of the joint parameters in different stages, and on the basis of the improvement of board-shoe racing running technique undertook academic exploration. Draw the following main conclusions:(1) Board Shoes is a multiplayer racing project coordination, technical forms. Chongqing men’s team to win a fast frequency, the Beijing men’s team are known for big stride, torso too far forward Guizhou characteristics of the men’s team, before folding, tilting technology is the unique characteristics of the Qinghai men’s team. From the technical point of view, we believe that the Beijing men’s and the Qinghai men, the technology is more sophisticated, reasonable.(2) At present, board-shoe racing running technique does not have a uniform standard, the technical difference is bigger, the pedal angle, anterior thigh lift angle and the front was minimal during knee angle of key technical parameters for comparison, between teams appeared statistically significant difference. (3) On the basis of the existing theory and the application of3D model exploration," we think that board-shoe speeder running process in three athletes in front of the thigh lift angle can improve to30°, so as to increase the objective step. Effects of anterior thigh lift angle is the main factor in three athletes between the hip distance.(4) The running process, reduce the players swing leg knee angles especially decreases when the thigh and perpendicular to the ground when the knee angle, can reduce or even avoid shoe friction with the ground. In general, when athletes ankle joint angle is90°, the knee joint angle of130degrees can be achieved the purpose to avoid friction.(5) Due to equipment limitations, step to improve the limited space. To ensure the proper step under the premise, to improve the athletes running cadence will be to improve the sports achievement is the effective way of board-shoe speeder.
