Sprinting fast is much more than just putting on a pair of sprinting spikes and heading out to the track while moving as quick as possible. Being able to run fast times requires a combination of relaxation, arm swing and leg action. All Olympic sprint champions have mastered the major objectives to a level of perfection. As a beginning sprinter you must seek perfection in every aspect of your sprinting mechanics so your own body might move more efficiently.
The most important part of sprinting that you ought focus on is practicing to remain relaxed while sprinting. Your own sprinting movements must be fluid with no jerky action. You will often discover the slowest sprinters on the track are the ones that often tense up during their races. Your eyes must be focused straight ahead at the finish line and not be focused on your own competitors. Your own jaw must slack a little to prevent your neck from tensing up while you are trying to accelerate your body fast. And remember to breathe while sprinting, this will help keep your own body relaxed and free from oxygen starvation.
While maintaining your total body relaxation while sprinting, just create sure that your own arms are moving through their proper movements. Your hands should not come up higher than your own chin level during the front swing and during the back swing you should cue your hands to place an object in your own back pocket. Moving your arms to the proper position during the back swing allows your own hips to rotate easily and it also allows your own legs to open up your stride length.
An open stride length should be your important focus while moving your legs down the track. In order to keep your stride length open and fluid you must focus on your own feet stepping over the opposite knee during the leg cycle.
