A Study On The Application Of Liquid Loading And Curved High Arc Training In Bar-crossing Technique Of Fosbury Flop

Fosbury bar technology is good or bad,mainly depends on the athletes' technical movements and ability in the rod and rod,and the size of the H3 value,the thigh and trunk angle and speed are the key under the bar,rod and bar reflects the athletes technical movements and ability.General high jumper in the bar when it is difficult to make the body center of gravity in the vertical bar,reasonable combination,this distance is H4 mainly depends on the flight angle and take-off distance therefore,H4 value is not a key to solve the problem under the rod and rod.So in our daily bar training focus will be on the short distance of H3,increase the amplitude of dorsal arch,narrow angle between the thigh and trunk,speeding up the pole speed at the same time,in order to improve the athlete's amcebar techniques and ability.This paper adopts literature data method,expert interview method,experimental method,video analysis,mathematical statistics and other research on liquid bearing arc application technology training platform bar in Fosbury Flop,analysis of the effect of liquid loading arc amcebar techniques and ability training platform of Fosbury,explore liquid the arc loading platform in Fosbury Flop application effect of special technical training in the bar,the advantages and disadvantages of special technical training equipment in the bar the development of Fosbury Flop,improve the science and effectiveness of the training of the bar.Through the summary and analysis,the following conclusions are drawn:1 liquid loading is the traditional sand vest for water vest,and moisture into a plurality of equal parts with stripes,the overall shape is similar to wear life jackets,convenient and comfortable,but also can effectively improve amcebar techniques and ability.In the take-off and process in the bar by the flow of water and liquid loading coat weight,increase body weight,improve the balance ability of the take-off leg support ability and body in the jumping process,but also enhance the ability to adapt to the muscles of the heavy load on the rod;and the rod in the process of accelerating the athletes too the rod speed,reduce H3 value,increase the utilization rate of H2,and decreases the angle of athletes' torso and thigh,increase the athlete back bow range.In this way,it not only improves the technology of athletes,but also improves the ability of passing the pole.2 high level athletes in the arc is four step run-up and take-off run-up arc based on the production of 0.3m and increase the height of the curved platform.The arc isdesigned to make the athletes run-up and take-off in conformity with the technical movement structure,force characteristics and direction of force flop arc run-up and take-off,and increase the height of the tower,just can make athletes in the 4-step 5short distance training in the run-up to bar easily even more than their target height,fully understand complete the action bar space in my sense of the target height.3 liquid loading arc arc run-up training is high,three in one "training means and training high liquid weight training combination",can let the athletes in the short run the bar to make full use of liquid loading clothes to improve bar action,easily cross the target height,at the same time,this training method can not only make professional athletes bar training,also can make the preliminary master non professional athletes Fosbury Flop action bar technique improved the lever action,not the ability to control and run recipients over the pole height limit.4 by means of training high liquid loading curved Fosbury bar high jump training than conventional bar training on athletes special technical improvement and special ability enhancement effect is more obvious,more exercise performance increase.
