1. General NotionsRunning sprints or run a short distance is run, which travels the distance between 50 m up to a distance of 400 m is therefore the main needs to run a short distance is speed. Speed in the short run is the result of a strong and rapid contraction of muscles is converted into a smooth movement of the lancer and the efficient and much needed for the runner to get high speed. A short distance runner (sprinter) potential when viewed from the composition or arrangement of muscle fibers the percentage of muscle fibers is fast (fast twitch) or higher with greater ability to 40 times per second in vitro muscle fibers than with slow (slow twitch) with the ability to 10kali per second in vitro. Therefore a short distance runner was born/bakat is not created. An analysis of the structural achievements of the run a short distance and the need to correct the learning and training should be seen as a complex combination of processes biomekanika, biomotor, and energetic. Run a short distance when viewed from the stages ran consists of several stages, namely:stages of the reaction and impulse (reaction and drives)stages of Acceleration (acceleration)stages of transition/changes (transition)the maximum speed (maximum speed)maintenance phase-velocity (maintenance speed)-finish a run short-haul Destinations is to maximize the horizontal velocity, resulting from a push the Agency forward.Running speed is determined by the length of the step and frequency of steps (number of steps of unity of time). Therefore, a short distance runner should be able to improve one or both.
