The speed of sprint is technically: the technical links of sprint include starting, accelerating after starting, running on the way and sprinting. Of the four links, running on the way is the most important. ※. The factors that determine the speed are stride and stride frequency, and it is best to have both a higher stride frequency and a larger stride. In terms of quality, sprint requires very high quality such as explosive power, lower limb strength, agility and jumping ability. Therefore, we should not only pay attention to technical exercises, but also pay attention to physical exercises. In terms of equipment, a pair of fitted spikes and comfortable track and field shorts can also achieve twice the result with half the effort. First, technical training: 1, running on the way: 60~80 meters repeated running; 2, 25~30 meters to accelerate running; 3. Start practicing (focusing on quick response exercises); 4, the final sprint: often run at full speed1/kloc-0 ~120 meters, which is an effective way to strengthen speed endurance and sprint in the late 100 meters, but it is bitter and tiring. I hope you can stick to it and get good grades! 5. Be fully prepared 20 minutes before the game, fully open your joints, muscles and ligaments, and run for two 30-50 meters. It is very important to rest for 5-8 minutes before the game, which will effectively improve your sports performance and avoid injury. Remember! ! Remember! ! ! Second, physical exercise: 1, explosive force and lower limb strength training: In the training process, we should pay attention to the close combination of speed and strength. The main methods of training are moderate weight-bearing exercises, such as weight-bearing lift heel, in-situ negative barbell jumping, weight-bearing lunges and so on. While developing rapid strength, we should also carry out weight-bearing exercises to increase muscle strength. The main exercises are: squat with weight, lifting barbells in various ways, etc. And combine running and relaxation exercises.

2. Jumping power training: Developing fast strength and jumping power can effectively develop jumping power. Its main exercises are: 1, general jumping exercises: one-legged jump, stride jump, split-legged jump, frog jump, straight-legged jump and so on. 2. Jumping obstacle exercises: jumping hurdles, jumping deep (that is, jumping down and jumping up, the effect is very obvious and easy to do), touching high. 3. Many equipment in the gym can also improve explosive power and lower limb strength. As for which way is more suitable for you, it depends on your venue and equipment.

It is worth noting that the above-mentioned exercise methods, times and amount of exercise should be arranged reasonably according to your personal or practitioner's physique, step by step. Don't increase the intensity and density of training quickly, causing sports injuries and strain, and get twice the result with half the effort; But if the intensity and density of exercise are not enough, it will not get good results. The above methods are for your reference only. I hope to bring you good grades, improve your grades and get happiness in sports! !
