| The long jump is a track and field sport with complex technology.The athletes need to control the body well and complete the action of the take-off link in the high-speed running.The whole process requires the movement of the core area of the body and the stable high-speed conversion and coordination of the coordination between the whole body muscle group to complete together.In the process of long jump,to complete the power of the movement of each link is through the core area of the body of the upper to the lower limbs,the core of the human body is the hub,which forms a connecting link between the preceding and is a bridge between the onset of power transmission,the core body strength training can strengthen the sports to build the complete kinematic chain,improve the stability of the body during takeoff,long jump athletes keep more correct posture to help athletes will better integrate the upper limb and lower limb power condensing,improve the interaction between different muscle groups,avoid because of force to disperse the extra speed in take-off link loss and energy consumption influencing the full play of the take-off technology.This paper mainly through the experiment method,the analytical and statistical methods,data and video will be part of the novel core strength training methods and means to join the long jump athletes core strength training experiment,mainly explores the contents include the following:first,the core strength training for the secondary level man jump athletes in the influence of the aspect in the long jump take-off technology,including speed up the leapfrog,jump time,leaps horizontal velocity and the Angle.Second,the influence of core strength training on the core strength of men’s long jump athletes at the second level.Thirdly,the influence of core strength training on the special quality of second-level male long jump athletes is analyzed through experiments and the following main conclusions are drawn:1,The core strength training compared with the traditional lumbar abdomen training more,pay more attention to development of athletes at the heart of the deep muscles,can the body for athletes and feeling ontology to a new kind of stimulation,thus improve the nervous system to exercise the muscle coordination and control ability of lower limb movement of acceleration and deceleration function,strengthen hip flexibility when motion,acceleration in the process of running with the axis of hip rotation,after the experiment the experimental group athletes 30 metres sprints grades have improved significantly.2,Core strength training is characterized by using equipment make the athlete training the body in the unstable state,compared to the traditional practice waist and abdomen,more motivate athletes nerve center and the whole body muscle group concentrated force,stable core,the experimental group after 12 weeks of core strength training and core strength test data of long jump athletes was obviously higher than that of control group in the long jump athletes,it is concluded that the core strength training means than a single means of waist and abdomen,on improving the core strength athletes more helpful.3,After 12 weeks after experiment of the take-off technology test comparison of movement,the experimental group long jump athletes in the takeoff time,leaps horizontal velocity of the index data changes on a large range higher than that of control group of athletes,this is because the core strength training by addition to the traditional lumbar abdomen training,pay attention to your shoulders,hips,trunk,carried out under the "unstable" interface of training,core layer depth of give attention to two or morethings muscle strength development,improve the body exercise in unstable state when the body core ability to control the body supported by solid conduction of upper and lower limbs strength,It greatly reduces the loss of energy and time caused by the instability of the core area of the body in the take-off process,and improves the timeliness and accuracy of the approach board and take-off,as well as the standard and rationality of the take-off Angle. |
