Hello, my friend! I am a sports madman. I have been engaged in teaching and training for 20 years. I'm glad to serve you. Your question is: My answer: My tentative suggestion for sprint: 1, Start rhythm practice (explosive): Click click click is continuous and fast (it can be increased by 0. 1 sec -0.2 sec). 2. Reaction speed exercises: different starting sounds (cough, high-five, whistling and other exercises). 3, do more running: 30-40-50-60-80-110 meters. (increase absolute speed) 4. Running on the way (big stride and high frequency) 5. Solve the late sprint: try your best to cross the finish line. (It can be increased by 0.0 1-0.05 seconds) 6. What kind of auxiliary training should I do at ordinary times? Do more special running exercises and practice your skills well, and it will be easy in the future. 7.200-meter running method: the starting speed of the curve should be accelerated along the tangent direction. Don't run with 90-95% full strength when running in corners. The whole body leans inward, with the left hand swinging slightly and the right hand swinging greatly. After the turn, you should accelerate with all your strength, and the high center should stride. 8. Don't try your best to run in a corner, just run with 90-95% strength, and pay attention to the corner running technique. High center of gravity, large stride, high frequency and force 100% are required on the straight. 9. Catch it from the beginning. Pay attention to the rhythm of the start before getting on the runway, be sure to master the rhythm, and then run with a gun. 10, believe in yourself, run at your own pace, don't be disturbed by others (chasing after you), be domineering and keep a cool head. Special reminder: 1, the above methods are temporary to improve grades, and it is best to have long-term systematic training. 2, find a good coach 3, make a systematic plan wish: health! Have fun!
