Running faster requires excellent sprinting mechanics. In order to run fast times you need to have your sprinting mechanics down to perfection. One of the most important aspects of sprinting is your body posture. Having the proper body posture can make or break your sprinting success. Some people have a natural body posture that allows them to run fast times with ease and others have damaged their technique because of improper training over the years.
Just realize that while sprinting you should not run with the same type of mechanics throughout the race. When you are coming out the blocks in the race, you should have a natural body lean that extends from your toes all the way to the top of your head. You should not be bending from the waist while you’re coming out the blocks.
This natural body lean should last about 15 to 20 m during your sprinting race. When you get to the 20m mark, you should slowly begin to rise up. This will allow you to make the most out of your acceleration and it will also keep you from getting too tired at the end of the race. Try to imagine a plane slowly rising up from the airway strip. You want to rise up from your acceleration phase very gradually.
As you begin to come up remember to keep your head right above your shoulders. This will keep you from leaning forward too much and it will also prevent you from having too much backside mechanics. Just remember to keep your eyes focused at the end of the track and to keep your head right above your shoulders.
