At present, coaches in our country pay more and more attention to the core training in athletes' quality training in their usual training, and they are applying more and more Swiss ball training methods. After training, their core strength, stability of the center of gravity, maintenance of body balance and coordination are all Played a positive role. Through experimental analysis, this article adds Swiss ball training to traditional training, thus enriching the methods and means of traditional core training. Core strength is an indirect influence on the performance of sprinters. This study mainly used experimental methods, mathematical statistics, and logical analysis to perform 4 tests of 50-meter run, run-up touch, standing long jump, and one-minute sit-ups on students in grades 5-6 of Anwai Santiao Primary School.

At present, our coaches pay more and more attention to the core training of athletes' quality training in peacetime training, and apply more and more to the Swiss ball training method, and after training, the core strength, center of gravity stability, maintaining body balance and coordination have played a positive role. Through experimental analysis, the Swiss ball training is added to the traditional training, thus enriching the traditional core training methods and means. The core strength is the indirect influence on the performance of sprinters. This study mainly used experimental method, statistical method, logical analysis method, three primary school students outside the 5-6 grade 50 meters running, running touch high, standing long jump and one minute sitting up 4 tests.

At present, Swiss coaches pay more and more attention to the balance and core strength training. In this paper, through experimental analysis, the Swiss ball training is added to the traditional training, thus enriching the traditional core training methods and means. The core strength has an indirect influence on the performance of sprinters. This study mainly uses the methods of experiment, mathematical statistics and logical analysis to test the students of Grade 5-6 in santiao Primary School of Anwai in four aspects: 50 meter running, run-up and touch height, standing long jump and one minute sit ups.<br>
