Long Jump Arm Takeoff Effect

With the jumpers continue to improve, increasing awareness of action is to jump off the main aspects of technology, and, this conclusion has been a lot of theory and practice sports confirmed. The Take Off in the buffer by the take-off and kicking legs and swinging with the swing to the effective completion. By consulting the relevant literature and conducted and analyzed and found, at present, domestic and international action on the long jump take-off studies are focused on the take-off leg in the jump phase of the effect and its impact on their scores, and for swinging, especially the upper limb arm off the course in the role of the less, it did not attract enough attention. In fact, the swing arm technology plays a very important role in coordination and cooperation on the lower limbs. Many foreign athletes, all with excellent speed and ahead of the run-up, and also off the pedal with good accurate technology, which achieved excellent long jump to lay a good basis for well-off.However, a good approach and Jumping by a solid technical foundation is a foreshadowing. Both the run-up speed, forward of, or the accuracy of all the pedal off and athletes with upper and lower extremities are inseparable. In general, the lower extremity is occupied oriented role, the foreign athletes have a good technical advantages of lower extremities, many scholars have lower limb technology more deeply. Generally, we believe that in the run-up in the long jump, start, buildup, on the way to run, four links front of the board to speed up that run-up technology is the key to good or bad, so whether in teaching or training, coaches or teachers attach great importance to lower limb technology in order to more directly improve the long jump faster. Upper arm in the teaching and training in technology, the general attention from teachers and even coaches, and teaching methods and training methods are more simple. Therefore, we often see that many students or athletes there is a big problem arm movements. For example, lack of coordination, not positive, the direction is not straight, stiff and so unreasonable technical phenomenon. In fact, such a mistake again significantly influenced the technology players in the run-up or jump in with the upper and lower extremities, upper and lower limbs without perfect coordination of movements, in fact, long jump is very restricted, and the results more or less affected play. Some scholars or experts that:"the faster the arm action, leg action sooner," "The more smooth arm movements, the more stable pace," "run-up speed of arm plus leg swing." As a result, we can see that the technical effect of upper arm on the long jump approach and take-off has a very important fact. Therefore, teachers or coaches in teaching and training should not only attach importance to the Athletes Lower Extremity Technique, and completely ignore the technology, especially the upper arm movements. Incorrect technique can cause upper limb movements are not consistent throughout the technology uncoordinated, and even the formation of the wrong technology movements, such as a large extent influence the accuracy and speed of run-up, serious, it will also affect the long jump in the play.Accordingly this paper, upper arm technology, through the Shaanxi Provincial Sports School track and field team six 18-22 year-old man two long jumpers to three experimental studies:First, the swing arm technology can enhance the athletes in the run-up in the lower extremities after pedal power experiments; Second, Hand palm arm in arm with the palm arm fist half of the frequency difference between the existence of different experiments; third, upper arm technical assistance for improving the running long jump in the frequency of the experiment. Through these three experimental results of this study:1, in order to play the lower extremity leg strength is not simply the maximum use of the supporting leg after kicking. After kicking strength is derived from the overall action, after the pedal arm can increase leg strength, so that the forward to the run-up and speed are of great help.2, the hand arm forearm half-fist shorter distances, and Hand palm arm can improve the run-up speed. Because the arm does not have the palm of your hand palm fist half of the traction. Arm strength and a small range. This will affect the run-up speed of play, because of its lower limbs when the run-up to improve the frequency and stride length is not large.3, experimental data show that athletes with and without arm swing arm, and even arm is good or bad impact on the approach of the step frequency is very large, and the effect of stride frequency is good or bad decision to take off one of the factors.Currently, Long Jumpers speed of ten meters in the run-up has reached the final 10.65-11.25m/ s, high-speed run-up in such a case, if you want the level of achievement in the long jump to a new stage, to further improve athletic performance, challenge to human limits, then kicking off the moment technology is highly placed unified, coordinated force to become the key to the take-off action, and therefore the study arm off in the process of Kinematic Characteristics of action, and the technical details summarized the problem, summarize, a complete, theoretical significance of the research results, to find some things with regularity, the long jump more systematic and complete technology projects to make the training more scientific and relevant, so as to effectively improve training quality, to get more good results and create conditions.
