A037: The Influence of Absolute-Speed Training Under Long-Jump inTake-Off Area on Run-Up Performance and Results

<bold>Purpose:</bold> Recently, the IAAF put forward the idea of changing the long jump to the starting area, and the implementation of this rule will inevitably change the training strategy of the long jump event. Compared with pedal take-off, the speed of running under the take-off zone rule has a greater impact on performance. Therefore, this study adopted the measurement methods of take-off zone and take-off board. The take-off zone was to take the take-off position in the area as the starting point for measuring the long jump distance. Compared with the traditional pedal take-off, the difference in the run-up performance and results of absolute speed training under these two take-off methods were analyzed. <bold>Method:</bold> In this study, 16 student-athletes were divided into the area group and the board group by the method of literature, experiment and video analysis. Before and after the intervention, three times a week for eight weeks, the 30-meter run, the 30-meter run between marching, the standing long jump and the long jump were tested. The average speed of the last 5 meters and the last 5-10 meters of the long jump run-up were collected and the differences before and after the experiment were compared. <bold>Results:</bold> (1) Both the 30-meter run and the 30-meter run between the two groups improved, and the standing long jump performance did not change significantly. (2) There were no significant differences in the speed of the last 5-10 meters of the run-up between the two groups, but the speed of the last 5 meters of the board group decreased significantly along with decreased stride length (p &lt; 0.01). (3) The speed of the last 5 meters and the last 5-10 meters in the zone group did not change and the stride length was average. <bold>Discussion:</bold> (1) For the starting area long jump, absolute speed training can improve performance. However, the effect is not satisfactory in the springboard long jump, because the stride length and rhythm change with speed. (2) In the starting board long jump in the speed training at the same time with the run-up rhythm of training to achieve the best results. (3) If the IAAF promotes the starting area long jump, athletes with strong speed will have greater advantage, while "technical" athletes who rely on pedal accuracy may face greater challenges.
