In sprint, the inner eight characters accelerate and the outer eight characters accelerate. How to practice,

The inner eight-character mainly refers to the process of kicking and landing in the interval between starting and accelerating, which is a running method with backward inclination and inward inclination of the foot center. This is a technical action, mainly to practice squatting and start, thus forming a figure-of-eight acceleration. This technical action is not deliberately made, but gradually formed on the basis of strength. So we should strengthen the training of strength and departure!
