Has anyone who has researched the biomechanics of the free-style stroke
have any comments concerning the possible effects of amplifying the
magnitude of "hip rotation" in the free-style stroke?

It seems that with increased hip roll, more of the recovery arm/shoulder
will be out of the water and thereforce reduce the drag resistance upon
the system. Additionally, if the arm/shoulder complex is further out of
the water the opposite segemts will be deeper in the water - possibly in
a region of decreased turbulence. Could this technique adjustment result
in a net reduction in drag resistance, thereby increasing stroke power
output if other factors remain unchanged (stroke mechanics etc..)?

Any information is appreciated.
