The Research Of Swing Arm Strength Training Equipment Of Sprinter Project

Research purposes:Studies have shown only when the specific strength exercises close to meet or exceed specific requirements that the competition can achieve the desired results of training.Coaches are in pursuit of a much more suitable arm force of the training methods,but they do not have the appropriate training equipment.In order to give coaches,athletes with an arm at close to or in line with the technical arm movements under conditions of specific strength training equipment,this study will provide an arm strength training of sprinter project,that is to achieve specific arm strength training which close to or load special technical movement requirements,and also realize the practical implementation of simple structure,low costs and high quality,easy to operate popularize.Research Methods:(1) Literature Information Method;(2) Interview Method;(3) Test Method.Research results:In this study,the swing arm strength training equipment of sprinter project used by the technical program are:it includes the base,a pair of brackets and a pair of load resistance transmission,that is a pair of symmetrical stent fixed at the base of the right and left sides,a pair of symmetrical load resistance transmission mechanism installed in the top two stents,the agency includes round resistance,friction belt,axle,swinging rod and the transmission rod,the axle Installed on the bracket,outer axle end is fixed with the resistance wheel,inner part placed on a post,friction band sets up at resistance round,and installed with a tensioning adjustment device,the lower end of pendulum rod connect with the outer end,on the drive rod transmission-side rod where there is a pair of arms moving simultaneously lever. The project spring arm strength trainer which mentioned above,the load resistance transmission device equipped with load instructions,the device including the dial,pointer and the pointer shaft,Pointer shaft installed on the bracket on its side is fixed with the pointer,the other end fixed with the friction, the dial fixed on the stent.The above-mentioned project sprint arm strength training,and the swing rod Constitute by the plug-in kits and inserted take- over, transmission rod constitute by rod plug and plug in kits,the bottom bar of the plug is fixed with the outer end of the rod plug.The above-mentioned project sprint arm strength training,and has the pedal at the base of the machine,Stent constitute by the first half and the second half of aircraft plug,the first half has a number of pin holes that can plug for the high adjustment bolt.The second half of the shelves has one or two bolt holes.In this study,the innovation of the equipment:it can be able to close and in accordance with the specific action requirements when use of the arm strength training equipment,so that sprinters can conduct the strength training without undermine the technical arm movements.In this study,the working principle of the equipment:adjust height of axle,length of swing rod,two wheel's width of the rod arm moving file,so it can meet the requirements of body shape of practitioners.Practitioners stand on the base of the pedals,Peg-leg the knees,the body lean forward or maintaining straight,the two arms separately move into the both sides of simultaneously baffle arm,the arm bent 90 degrees,with the bottom of the upper arm close to the arm action of the roller shutter sync.Practitioners to do forward and afterward moving of the arm.During the Process,arm will move simultaneously with the transmission pole,swing rod,axle and resistance synchronized round of Sports.It will have the load resistance when the friction of the resistance round rubs with the wheel friction.Load resistance can adjust the size of load resistance by adjusting the tightness of friction belt of the tensioning adjustment device,Load resistance value can display directly through the load device.Research conclusion:(1) in this paper,the swing arm strength training equipment of sprinter project could provide a new training methods to sprinters, and it could meet the requirements of the coaches and athletes when they do practice exercise arm strength.(2)In this paper,the swing arm strength training equipment of sprinter project could enable the sprinter's arm strength close to and in accordance with the special request of action,it can meet the requirements of the arm swing amplitude of the technical movements,reverse movement of Shoulder axis,and the in and out action of the pendulum arm.(3) In this paper,the swing arm strength training equipment of sprinter project could meet the regulation height from 157 centimeters to 190 centimeters of sprinter athletes to do the arm strength training,the range of equipment height:1260mm-1710mm,adjust spacing is 50mm;shoulder width adjustment range:(130+50n) mm-(410+50n) mm,and n=1,2,3,4,5,6,7; swing rod length adjustment range:170mm-250mm,adjust spacing is 20mm;(4) In this paper,the swing arm strength training equipment of sprinter project could meet sprinters needs to do different intensity strength training. The range of the load resistance adjustment is:0-7.9kgf.(5) In this paper,the swing arm strength training equipment of sprinter project has gained the National utility model patents,patent No. ZL200820077097.6.
