Fig. 2. Relationship between moment arm and oxygen consumption rate
(
O2) in ml
kg–1 min–1 at 16 km h–1.
Dots are individual participants, the line is the best fit for the theoretical
model y=ax–2+b, where x
is moment arm in cm and y is
O2 in ml
kg–1 min–1 at 16 km h–1
(a=–628.1, b=75.65, r=0.77). This model was
derived from Eqn 7, assuming a
linear spring (n=1). A very similar fit with r=0.76 can be
obtained for the model y=cx–1.5+d, which is
based on the assumption that n=2.
