Very true! it is illustrated in the video at the
bottom of the page of

http://www.livescience.com/humanbiology/050915_walk_run.html

as "level walk": you keep the Centre of Mass (Centre
of Gravity) on the same plane,eliminating bobbing up
and down, reducing the necessary energy for
locomotion. Actually if you minimise the lateral
displacement of the CoG as well by putting one foot
exactly in front of the other, as accomplished runners
would do,it would move as if it was on a rail and the
effort is reduced even further.This is what we do in
Argentine Tango, but at (usually) reduced
speed......Sliding brings in friction, (resistance
from the floor) and as a consequence requires more
effort.

Cheers,
