Elite Women's Hurdles Hurdler Of Technical Diagnostics

In this paper, Wang Li, Zheng Yarong, Sun Ya-three players for the study of micro, reference previous research methods, the use of technical means of Biomechanics in all aspects of the hurdles, the technical details of the recording and analysis of quantitative and technical analysis that parameters and modern Hurdles required technical parameters and the other world best Hurdles technical parameters of a comprehensive analysis, comparison, find and describe the Elite Female Hurdles Wang Li, Zheng Yarong, Sun Ya slight hurdle technology characteristics and laws of , and found the lack of technical hurdles and advantages, and put forward their views and suggestions. To further improve WANG, Zheng Yarong, Sun Ya-Micro-and short-distance hurdle race of the overall level of movement, and promote the development of track and field training to do some scientific value and practical application of theoretical significance; also take the opportunity to track and field team for the Shanghai Women's 100m hurdler developed the enormous potential to do some contribution, Wang Li and Zheng Yarong under the specific circumstances of different training methods and means used to provide a theoretical basis to meet the technical diagnostic purposes. The results show that:1.Advantages and disadvantages of Wang LiWang Li's advantages are: more stable hurdle rhythm, the better ability to start and sprint; field frequency between the 3-step running faster, more stable; from across the minimum knee angle when the swinging leg least conducive to narrowing the radius of the fast swing; landing stage , Wang Li distance under the appropriate column, the angular size of the suitable land, the focus of the course of undulating ground, so the ground swinging leg WANG shorter, faster into the bar room to step 3. Wang Li's weaknesses are: the ability to create the highest rate of poor; been vacant for too long column, the total field over the total time spent too long vacated; from the inter-stage, cross the distance from a longer length of Wang Li, from the moment the center of gravity vertical velocity is too large to resulting in cross-angle is too large since the same time, Wang Li on the cross bar from the knee kicking leg angular velocity is small, these factors have been vacated so that the column A. at a longer length of time, affecting the total score; flight phase WANG minimum anteversion trunk is too large, too large margin increased focus, swinging leg thigh after the Bar is not actively under pressure, which also contributed to the important factor in the flight time is too long, should be actively corrected.2. Advantages and disadvantages of Zheng YarongZheng Yarong advantages are: the rhythm is more stable. Zheng Yarong's weaknesses are: whether it is vacant field between the Bar stage or stage of Step 3 does not highlight the advantages, with the other athletes there is a big gap between the need to further tap potentials.3. Advantages and disadvantages of Sun YaweiSun Ya slight advantages are: to create the highest rate of capacity columns better; too time-consuming the least amount of time vacant column, the column over the hurdle of their respective time to reach or exceed the level of elite athletes in the world, so the bar will have its advantages Action Technology ; from the inter-stage moments from the center of gravity to the horizontal and vertical velocity is more appropriate, from the cross point of the smallest cross-legged on the bar from the time the maximum angular velocity of knee kicking, which are its greatest strength, should be properly maintained; the flight phase, the smallest increase in its focus, swinging leg thigh after the Bar had positive under pressure. Sun Yawei's weaknesses are: hurdle rhythm is not very stable; bar between the 3-step step frequency need to be further improved; Sun Ya slight start and acceleration is poor, also need further strengthening; landing stage, Sun Ya micro landing angle is too large, the focus fluctuation is too large, these two factors caused the same time its long swing leg support.
