Hubei Approach Speed In Long Jump Athletes The Utilization Range Of Research

Long jump is a sport with a long history, it gathers speed, strength, coordination, balance, and the appreciation of the beauty and a suit. Also has a long history tradition. Its core technology-takeoff and technology from the earliest squat type rise up to the development of the middle type, as well as the evolution to the present technology mature, the most suitable for walking type of long jump. Every technology has a big influence to the result. Complete the long jump technique contains run-up, take-off, movement and landing the suspension parts., one of the most important influence on the performance, the largest is the run-up speed and athletes want to get good grades must strive for perfection and a key part of the training. In the progress of science and technology high speed development today, the athletes to performance requirements are higher, constantly promote reform of the long jump technology, continuous exploration and pursuit of better run-up technology, can improve the long jump, promote the development of long jump movement and move forward.This article through the literature material law, questionnaire survey method, mathematical statistics, data analysis, expert interviews and other methods, constantly at home and abroad and browse the famous long jump articles of literature, collecting and long jump athlete of long jump run-up, take-off related information and the data were analyzed. Through to the domestic excellent long jump athletes and hubei region utilization rate of approach speed in long jump run-up speed and comparative analysis of the two aspects as arguments to the scope of this article finally concluded that utilization of approach speed in most conclusions of technology, research meaning and existing problems of the argument. To hubei area20long jump athletes at the same time analysis of test data, analysis the suitable man utilization rate of approach speed in long jump athlete’s effective range. The results showed that:1. The utilization rate of approach speed is too high, which is run at a faster rate than its control range, the moment of recoil force is too big, cause the jump leaps Angle is too small, affect the performance. In circumstances beyond its control run-up speed, athletes in order to accurately upper plate, in the last10m to reduce the speed, impact during the takeoff spe At the same time can make the last two steps and long is too long and stride frequency is low, the stability of the stability of the takeoff and pedals as a negative impact. If not effectively improve the corresponding strength training, not only reduces the level of run-up speed, but also not conducive to the play of vertical velocity after takeoff.2. Through the study of this article found that domestic athlete’s run-up speed utilization range exists, the effective range is between93.5%and95%.3. in the specific stage of the run-up speed increase, due to the improvement of exercise intensity and excitement to break the original technical system, impact performance; Match the run-up speed need to improve the technical system, formed in the run-up speed of spiral technology and performance as a whole. Due to the particular phase jump run-up speed improvements of takeoff leg load increase, the formation of the weakness of the original power carrying capacity, impact performance; Need to improve the power quality of the match the run-up speed system, to achieve the matching speed and load capacity of different levels of ideal mode, and improve performance.4. The phenomenon of the "U" shaped not all players will appear, also is not peculiar to only a small amount of athletes, he can only reflect in a certain level of athletes. Because each player has its specific run-up speed rhythm, can complete the takeoff is largely depends on the run-up rhythm of master, so in the experiment to test the change of the object to carry on the run-up speed, affect the real value of the jump performance. The determination of absolute velocity has a lot of uncertain factors. Athlete’s injury, different motion state, the training week time will affect its absolute speed and the performance, and absolute velocity change of0.1m per second will be1.0%-1.0%of the impact on utilization rate of approach speed, so the absolute velocity measuring volatility will affect curve model. It is worthy of our reflection and improvement in the future research.So we are looking for the maximum utilization rate of approach speed range at the same time also to scientific training, through training to strengthen their various aspects ability, can in the case of high utilization rate of approach, also can have a higher success rate and accuracy, to maximize performance enhancing.
