From The Perspective Of Kinesiology To Analyze Technique Of Our Elite Female Race Walkers

In recent years,the progress of track and field events in China has improved gradually.With the continuous development of science and technology and training methods,the walking event has also achieved outstanding results and sprung up a large number of outstanding young athletes.Young athletes as the bench talents have also been considered.Walking race athletes have a long training cycle,and a good athlete needs to undergo scientific and hard training for many years.In the youth stage,the technique of race walking has a great influence on the adult's performance,so it is very important to train good technical movements in this period.According to the research object,which are the six outstanding young female athletes in the group of National Grand Prix race and Olympic trials held in the Mount Huangshan in Anhui in March 2016,the study used the test method of two-dimensional video,and used Dartfish8.0 image processing software for technical analysis,then compared technical indicators on two aspects,walkers ensuring the game and influencing the performance,specifically analyzing on walking athletes' stride length,stride frequency and included angle when thrusting on the ground and against the ground in the game steps.According to the overall kinematics analysis of the young outstanding walking race athletes in China,it is expected to find out the characteristics and commonalities of the excellent young athletes in the field of technology.At the same time,we will enrich the theoretical system of our country's walking race project,and provide some references and some suggestions for the skills and training of young walking race athletes in China to achieve high standards.Conclusions1.The flight time of outstanding Chinese young female athletes is relatively reasonable,and the ratio between single step length and height is ideal.Meanwhile single leg appears the "arch" phenomenon when single supporting phase,which indicates that Chinese outstanding young female athletes' technical qualification is ideal when ensuring the completion of the game.2.Outstanding young female athletes in our country need further improvement in the vertical displacement of the center of gravity,and the individual technical aspects of the included angle are not reasonable.Some technical indexes of single qualification have great difference with top athletes,and technical movements are not balanced,not delicate,not well balanced with each other.3.The average step length of outstanding young Chinese female athletes is(left)and(right)1.105 + 0.02 M 1.105 + 0.03 m,197 /min frequency step,and the vertical distance of rise and down in a step of the center of gravity is 6.13 + 0.66 cm,and the flight time is(left)44.5 + 7.12 ms,44.83 + 5.67ms(right),and joint angle when single knee supporting is(left)185.45 +-2.941 degrees,2.953 degrees(right)184.07.4.There are wide gap on step frequency when comparing between outstanding young Chinese female athletes and athletes.Also there is a certain gap on the angle between the foot and the ground between athletes of domestic excellent young female walking race and the world-class when touching and leaving the ground.When the two supports are used,the angle between the legs is not big enough,and the rotation of the hip joint is not large,and the flexibility is relatively poor.The swing range of upper limb is not enough,and some athletes have yaw.
