A Study On The Kinematic Factors Affecting The Race Walking Technique Of Juvenile Male Race Walker In Yunnan Province

Walking is advantage of track and field events in our country, and the advantages of the project in Yunnan province. Race walking athletes in our province in the domestic competition in the international competition and performance differences. Competition abroad many times in a foul sent off. Race walking athletes in our province has unique plateau training condition, if in race walking technology can improve to improve, so will show more obvious advantages in foot races. Is through the adoption of literature method, mathematical statistics method, shooting sports biomechanics method, the methods of image analytic method to youth man race-walkers in Yunnan province as the research object to study and analysis, find out the influence of Yunnan province adolescence man race-walkers kinematics of the factors, put forward countermeasures to improve consulting teenagers walking development in Yunnan province. By studying the following conclusions:1) Teenagers race-walkers in Yunnan province still belongs to "small steps, fast pace" technical style, and our province young man body centre of gravity of the walker on larger speed fluctuations.2) In Yunnan province youth men walkers its instant ankle landing Angle too obviously unreasonable in touchdown instant technology should be improved; In the vertical moment technique of the walker is a reasonable stability; After a moment from the ground push phase technique is reasonable; On the Angle of the swinging leg and the Angle of two thighs is very reasonable.3) In Yunnan province youth man arms swinging technique of the walker is very reasonable; In terms of lower limb swing speed, our province youth men walkers hip, knee, ankle, feet on the swing speed are not obvious.4) Provincial youth race-walkers hip movement forms are not of the space form, but around a certain movement below. Two hip in the swing phase turned downwards not reach the designated position, coordination is not enough, lead to the motion of the hip is not stable.5) Yunnan youth men hang time all of the walker in fuzzy decision within the time limit; In the process of walking on technologies and no curtains crus of wrong action, not easy to be the referee decisions to vacate. But the ups and downs on the distance of the top of head, head rolling distance is affect our province youth man fast walker technology factors of joints. In terms of bended leg decisions, our province youth man race walking athletes also have few bended leg.
