A Study On The Characteristics Of Speed Rhythm Of Athletes At Different Levels Of Women's 100m Hurdles

Hurdle project was once the Chinese track and field advantages of the project,with the Liu Xiang London Olympic Games injury,China's hurdle project also fell into the trough.2014 Incheon Asian Games,China's young women's 100 m hurdles athletes Wu Shui Jiao,with 12.72 s excellent results won the first one,the results ranked first in the world 14 th,so that we see new hope.Wu Shuijian won the championship at 12.85 s in the World Track and Field Challenge(Beijing Railway Station)in 2015.The same year,Beijing track and field world championships Wu Shuijiao and historic break into the semi-finals,but gave us unlimited expectations.China Straight Hurdle has had Liu Xiang to achieve the world's top level of successful experience,but also that the Chinese athletes in the hurdle project,as long as the grasp of the characteristics of hurdle project,give full play to their own advantages,can be a breakthrough.Throughout the years on the hurdle project research found that scholars on the hurdle full speed and time parameters,hurdle technology,hurdle teaching and other aspects of research more,but rarely on the different levels of active athletes between the technical parameters of the comparison the study.This article will be held in 2015 Beijing World Championships,2015,2016 World Track and Field Challenge(Beijing Railway Station),2015 National Athletics Grand Prix(2nd),2016 National Athletics Championships,2015,2016 National University Athletics Championships Women 100 m column data for the study basis.The regularity of the rhythm of the whole rhythm of the athletes at different levels is taken as the object of study.Using the methods of literature,video analysis,mathematical statistics,comparative analysis and logic analysis,through the different levels of women's 100 m hurdler time(analysis accuracy of 1 / 100s)and velocity parameters of the women at different levels of 100 m hurdles,the difference between the speed and the rhythm of the different levels was analyzed and analyzed,and the women's 100 m The technical characteristics of the speed of the project are beneficial to enrich the special theoryand provide the theoretical guidance for the teaching and training.The conclusions are as follows:1.different levels of women 100 m hurdles athletes in the column time,Jiangan Group,a group,two groups and the next level there are significant differences between;In the hurdle to run this technical aspects of the three steps there is a big gap between the time.Mainly related to running cross-spanning technology level,reflecting the different levels of athletes on the hurdle special technology to master the degree.Indicating that there are significant gaps in the two core technical aspects of the column technology and the hurdle,and the main technical reasons leading to the achievement gap.2.Different levels of women's 100 m hurdles athletes to maintain high-speed ability is one of the important factors that lead to different levels of 100 m hurdles athletes.The acceleration of the start phase of the gap,mainly to start the acceleration and start the first column of the technical differences.3.Different levels of women 100 m hurdles most of the athletes in the starting speed in the 3 to 5 columns to reach the peak speed to a faster speed to maintain the distance between 3 to 4,and then began to decline to the first 10 columns,into the final level sprint The speed again increases the speed characteristics of the secondary acceleration.Part of the two groups of athletes in 1 to 2 column peak speed,the lower the level,showing the maximum speed between the bar as soon as possible and the level of the sprint stage to enhance the speed of the more significant features.The full speed rhythm shows a "~" type of change characteristics,indicating that women 100 m column full speed changes in the overall characteristics.4.The maximum cycle speed is not only the difference between the different levels of athletes the largest speed index,The maximum cycle speed was negatively correlated with the grade(r=-0.984**,P<0.01),But also to enhance the overall speed of the hurdle level important speed characteristics.5.China's most outstanding women's 100 m hurdler Wu Shuijiao compared with the world's top athletes,hurdle cycle reached the maximum level of world-class,three-step step between the bar slightly better than the world's top athletes.But the gapbetween the high-speed ability to maintain a large gap,vacated over the bar for too long,indicating that the hurdle step technology there is a certain problem;to maintain the speed of the lack of ability and sprint fatigue is mainly due to the frequency of excessive decline due to frequency.6.The establishment of time pattern of women at different levels of 100 m column is beneficial to the different levels of athletes as the training and competition reference and evaluation standard,which has practical guidance and reference significance for teaching and training.
