Can the athlete's feet fly when sprinting 100 meters?

When the athlete sprinted 100 meters, his feet flew for a while, but he didn't jump up, which was caused by the too fast pace frequency when running at high speed.

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 taking standing, turning and starting between races will also help to improve your speed.

The above training to improve speed should be carried out on good quality pavement, that is, flat, dry and moderate hardness pavement. 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.

Special running exercise

Small step run

Relax your upper body, keep your shoulders straight and swing your arms back and forth naturally.

Relax your hips, knees and ankles. When stepping, your knees lean forward and your hips rotate slightly.

When the knee of the swinging leg swings forward, the thigh of the other leg actively presses down and the forefoot touches the ground. When touching the ground, the knee joint is straight, the heel is raised, and the ankle joint is elastic.

Leg-lifting running

The upper body stands upright or leans forward slightly, and the arms swing back and forth.

The thighs are swinging forward to the level, and the hips on the same side are driven forward slightly. The legs and legs are folded as much as possible, and the heels are close to the hips.

While lifting the leg, the thigh of the other leg actively presses down, and the front side of the straight leg touches the ground. The center of gravity should be raised and cushioned with the ankle joint.

Reverse pedaling

The upper body stands upright or leans forward slightly, and the arms swing naturally.

Swing legs actively swing forward and upward, torso twists, and ipsilateral hips drive thighs to lean forward completely.

While swinging the leg, the thigh of the other leg actively presses down, the forefoot touches the ground, the knee joint and ankle joint are cushioned, and quickly turn to the rear pedal.

When kicking back, swing your legs to send your hips first, and push your knees and ankles back. In the flight phase, the center of gravity is forward, you should relax when flying, and the frequency of legs alternating should be fast.
