Diagnosis Of Women Speed Skaters Curving Technology Action Of China

In this paper, the use of image measurement and analys is method, obtainedthe kinematic parameters of the curve technology for Chinese youth female athletesin the data. By using the method of biomechanics of the Chinese elite youngwomen athletes bend technique were studied. The technical characteristicsof clear speed skating curve skating technology with. At the same timeas far aspossible from the various technical parameters of the speed skatingcurve technology to conduct in-depth research and make a diagnosis, as far aspossible for the comprehensive evaluation of the curve technology level speedskating athletes and to guide the practice of training and provide a theoretical basisfor reasonable.We get the following conclusions through the analysis and diagnosis of the fourathletes areproblems left leg as a support leg lack of strength, not a longtime to be asthe support leg and swing leg up with ice, causing left single support time. Li Qi shigreatly affects the whole process of the upper corner angle speed; its ability tocontrol the center of gravity of the general; the relatively large angle of lower limbsjoints (hip, knee angle and ankle angle angle) and take off leg lack ofstrength to lead the stride frequency step is small. In the static and the technicalparameters are basically in the range of excellent athletes in theworld (except between the left single support anddouble support time ratio) but thereis still a certain gap compared with Zhang Hong, especially for the control of thecenter of gravity. The curve skating technique of Zhang Hong, is thetechnologyoptimization of the four athletes. The upper body and lower limb jointangles (hip, knee angle and ankle angle is smaller, the center of gravityforward angle) and the fluctuation range is big, theswing legs with ice technology ismore reasonable; the small step length, stride frequency is high.Changes in eachstage of Zhao Xin upper body angle than the other players, and there is a significantdifference; leg strength deficiency in each phase of the ankle and knee angle is toolarge; the long, low step frequency.
