The is a skill that must be practised from a young age. The ability to run fast and have it look easy is of the highest importance. The quality of an athlete that can have very fast steps is the first thing that needs to be developed from a young age. Sprinters should not be instructed to run on their toes or to pump their arms high. They should also not move very far forward from the body.
Maximum speed is the most important quality to develop on a regular basis.
This should be done with maximum speed experiences over short distances. A maximum amount may be 3 sets of 3 runs over 60m. The athlete should never do more once they are getting slower within the session eg. If the times over 60m are 8.30, 8.20. Then they should have ended the session after the first obviosly slower run in the session and in the example that was the 8.60.
