Short Distance Running
Common sense
Sprinting is running a distance of between 50 m to 400 m distance. therefore a major requirement for short-distance running is speed. Speed in short sprints are the result of a strong and rapid contractions of the muscles are converted into smooth movements smooth and efficient and very necessary for runners to get a high speed.
A short distance runner (sprinter) potential when viewed from the composition or arrangement of the muscle fibers of the percentage of fast muscle fibers (fast twitch) is greater or higher with up to 40 times per second capability in vitro compared with slow muscle fibers (slow twitch) with a capacity up to 10 times per second in vitro. Therefore, a short distance runners were born / talent is not created.
A structural analysis of sprinting performance and the need to improve training and learning should be viewed as a complex combination of processes biomechanics, biomotor, and energetic. Ran a short distance when viewed from the stages run consists of several stages, namely:
- And boost-phase reaction (reaction and drive)
- Stage acceleration (acceleration)
- Tansisi-phase / change (transition)
- Stage maximum speed (maximum speed)
- Speed-maintenance phase (maintenance speed)
- Finish
Sprint goal is to maximize the horizontal velocity, resulting from a push forward. Running speed is determined by the length of step and step frequency (number of steps per time unit). Therefore, a short distance runners should be able to improve one or both.
