The correct way to land on the ground when running is to land on the forefoot and push it back hard to form a "scraping" action. If you touch the ground with your heel when running, you will not only run slowly, but also have a bad influence on your health.

Why can't you run fast with your feet? Because the heel will produce a force opposite to the running direction, which is upward and backward, it takes a long time to push the ground backward (backward) from the heel to the forefoot, which affects the forward horizontal displacement speed, and the running speed will naturally be slow. On the contrary, if you land with the forefoot, the braking force will be much smaller than that of the foot, and the forefoot can be pushed back immediately after landing, thus shortening the time of landing, so you can run faster with the forefoot than the foot. Runners only have nails in the forefoot of their feet, that is, they don't need to follow the ground when running.

Why does it have a bad effect on your health to follow the ground with your feet when running? Because the heel cannot be buffered by the arch of the foot, the vibration is much greater than that of the forefoot, which will make all parts of the body (including the brain and internal organs) vibrate; The calcaneus can also be damaged, leading to periostitis, or the calcaneus fat pad is damaged, causing heel pain. Therefore, it is necessary to master correct sports skills when running, so as to achieve the purpose of exercising and improving sports performance.
