Good stride length, bad stride frequency

[sprint1]

From what I understand, getting good frequency and a range of motion that is suitable to the athlete’s power is more important than trying to maintain the length at the expense of decreasing frequency if the athlete is not powerful enough for it. It isn’t possible to change their frequency from 4.1 to 4.8 while maintaining the same length. This is a 17% increase in top speed and will be more than 1 second improvement to their time (closer to 2 seconds). Perhaps shorten the stride length so that the frequency can improve, then as the athlete develops there will increases to both.

Well yeah, you can’t change it immediately, but what about the training necessary to get to that point? That’s mainly what I’m asking.
