Supertraining

Here's an insight from Charlie Francis:

There is a significant difference among athletes, but I have learned to
take a very conservative approach in deciding whether an idiosyncrasy should
be  changed or left alone.In some  athletes, there will be differences in the
way their leg musculature is attached  to the skeleton.  This results in
different lines of pull.
In absolute terms, each of your athletes has differences in body segment
lengths, location of muscle attachments, etc.  If the athlete is running
well, you  assume that the physical idiosyncrasy is not a factor.
If the athlete is able to run fast, smoothly and has no physical
complaints, I would leave the idiosyncrasy in tact.
Ben Johnson’s left knee carries out to the side when he runs.  So what?  If
an idiosyncrasy does not impact on  performance, don’t tamper with it.

Olympic gold medalist Evelyn  Ashford tilts over to the left.  That too, is
not a limiting factor-—for her!"
