We all expect instant changes, but a ripening result requires investment of time. Running your fastest, is not going to bring the "it" to the table, but it requires techniques; and adapting them requires time. One of the easiest tips is -- to throw away the arms every time you swing them backwards, as it can give you a definite speed boost.
It is also a neat trick that you shorten the forward swing as it makes the transition a whole lot quicker. Besides, as irrelevant as this sounds, running slowly actually aids you in becoming a fast runner.
The factors such as giving importance to the heart and lungs actually makes you a much better runner on the track, although it takes time to completely get used to it.
