Speed is obviously an important factor affecting sprint performance. Running at 90 ~ 95% intensity for 20 ~ 60m, 4 ~ 5 times for each group, 3 ~ 6 minutes for each rest, and 2 ~ 3 groups will help to improve your speed. At the same time, changing the starting posture of sprint and adopting standing, turning and moving starting will also help to improve the speed.

Warm weather will help to improve the efficiency of this training. Cold weather is not conducive to this kind of training, but it can be carried out after completing appropriate preparatory activities.

Extended data:

When running from the straight into the corner, the body should consciously lean inward, increase the strength and swing amplitude of the right leg, and correspondingly increase the strength and swing amplitude of the right arm, which is conducive to running from the straight into the corner quickly.

When running in a curve, your body should lean toward the center of the circle. When pushing back, the right leg should use the inside of the forefoot and the left leg should use the outside of the forefoot. The pedaling and swinging direction of curve running should be consistent with the tilting direction of the body to the center of the circle.
