Fig. 5. The lower support of the body during the downward displacement of the
centre of mass relative to upward displacement is indicated on the ordinate by
a ratio Rint,down/Rint greater than
0.5 at all running speeds (abscissa). Note that Rint is
the cumulative value at the end of the step of the instantaneous
EkEp transduction: data show
that the transduction of Ep into Ek
during the downward displacement is greater than the transduction of
Ek into Ep during the upward
displacement [see Rint(t) curve in
Fig. 7]. Statistics as in
Fig. 2.
